Dartmouth lies on the east shore of <a href="/facts/Halifax_Harbour/YlnVsHjh">Halifax Harbour</a>, and Halifax is on the west shore. By 1917, "Halifax's inner harbour had become a principal assembly point for merchant convoys leaving for Britain and France."<a class="footnote-ref" id="fnref:5" href="#fn:5">5</a> Halifax and Dartmouth had thrived during times of war; the harbour was one of the British <a href="/facts/Royal_Navy/Xdy8YCH7">Royal Navy</a>'s most important bases in North America, a centre for wartime trade, and a home to <a href="/facts/Privateers/PfeEkF2p">privateers</a> who harried the British Empire's enemies during the <a href="/facts/American_Revolution/zy1F0LxK">American Revolution</a>, the <a href="/facts/Napoleonic_Wars/jo0MdaTD">Napoleonic Wars</a>, and the <a href="/facts/War_of_1812/D94xlnn8">War of 1812</a>.<a class="footnote-ref" id="fnref:6" href="#fn:6">6</a><a class="footnote-ref" id="fnref:7" href="#fn:7">7</a>
The completion of the <a href="/facts/Intercolonial_Railway/5LRfFo3N">Intercolonial Railway</a> and its Deep Water Terminal in 1880 allowed for increased steamship trade and led to accelerated development of the port area,<a class="footnote-ref" id="fnref:8" href="#fn:8">8</a> but Halifax faced an economic downturn in the 1890s as local factories struggled to compete with businesses in central Canada.<a class="footnote-ref" id="fnref:9" href="#fn:9">9</a> The British garrison left the city in late 1905 and early 1906.<a class="footnote-ref" id="fnref:10" href="#fn:10">10</a><a class="footnote-ref" id="fnref:11" href="#fn:11">11</a> The Canadian government took over the <a href="/facts/Royal_Naval_Dockyard,_Halifax/WLgg9aIH">Halifax Dockyard</a> (now <a href="/facts/CFB_Halifax/vrFJExrN">CFB Halifax</a>) from the Royal Navy.<a class="footnote-ref" id="fnref:12" href="#fn:12">12</a> This dockyard later became the command centre of the <a href="/facts/Royal_Canadian_Navy/eSRkBetN">Royal Canadian Navy</a> upon its founding in 1910.<a class="footnote-ref" id="fnref:13" href="#fn:13">13</a>
Just before the <a href="/facts/World_War_I/vITTUanQ">First World War</a>, the Canadian government began a determined, costly effort to develop the harbour and waterfront facilities.<a class="footnote-ref" id="fnref:14" href="#fn:14">14</a> The outbreak of the war brought Halifax back to prominence. As the Royal Canadian Navy had virtually no seaworthy ships of its own, the Royal Navy assumed responsibility for maintaining Atlantic trade routes by re-adopting Halifax as its North American base of operations.<a class="footnote-ref" id="fnref:15" href="#fn:15">15</a> In 1915, management of the harbour fell under the control of the Royal Canadian Navy; by 1917 there was a growing naval fleet in Halifax, including <a href="/facts/Patrol_boat/Kg8FUMs2">patrol ships</a>, <a href="/facts/Tugboat/GJN1wj1d">tugboats</a>, and <a href="/facts/Minesweeper/6xFLcTF2">minesweepers</a>.<a class="footnote-ref" id="fnref:16" href="#fn:16">16</a>
The population of Halifax/Dartmouth had increased to between 60,000 and 65,000 people by 1917.<a class="footnote-ref" id="fnref:17" href="#fn:17">17</a> Convoys carried men, animals, and supplies to the <a href="/facts/European_theatre_of_World_War_I/FHWoxpbY">European theatre of war</a>. The two main points of departure were in Nova Scotia at <a href="/facts/Sydney,_Nova_Scotia/G8nS6l65">Sydney</a>, on <a href="/facts/Cape_Breton_Island/PSAWLQL0">Cape Breton Island</a>, and Halifax.<a class="footnote-ref" id="fnref:18" href="#fn:18">18</a> <a href="/facts/Hospital_ship/ICvc3WGR">Hospital ships</a> brought the wounded to the city, so a new military hospital was constructed.<a class="footnote-ref" id="fnref:19" href="#fn:19">19</a>
The success of <a href="/facts/U-boat_Campaign_(World_War_I)/2Ifsfslj">German U-boat attacks</a> on ships crossing the Atlantic Ocean led the <a href="/facts/Allies_of_World_War_I/HBo9sw1M">Allies</a> to institute a convoy system to reduce losses while transporting goods and soldiers to Europe.<a class="footnote-ref" id="fnref:20" href="#fn:20">20</a> <a href="/facts/Merchant_ships/Pg3Pa3EY">Merchant ships</a> gathered at <a href="/facts/Bedford_Basin/n3M9HkvR">Bedford Basin</a> on the northwestern end of the harbour, which was protected by two sets of <a href="/facts/Anti-submarine_net/d05FG000">anti-submarine nets</a> and guarded by patrol ships of the Royal Canadian Navy.<a class="footnote-ref" id="fnref:21" href="#fn:21">21</a>
The convoys departed under the protection of British <a href="/facts/Cruisers/wtAAm5nb">cruisers</a> and <a href="/facts/Destroyer/bkYL7bI8">destroyers</a>.<a class="footnote-ref" id="fnref:22" href="#fn:22">22</a> A large army <a href="/facts/Garrison/7XAH5arE">garrison</a> protected the city with forts, <a href="/facts/Gun_battery/lf2pfXQv">gun batteries</a>, and anti-submarine nets. These factors drove a major military, industrial, and residential expansion of the city,<a class="footnote-ref" id="fnref:23" href="#fn:23">23</a> and the weight of goods passing through the harbour increased nearly ninefold.<a class="footnote-ref" id="fnref:24" href="#fn:24">24</a> All <a href="/facts/Neutrality_(international_relations)/Ig022QPh">neutral</a> ships bound for ports in North America were required to report to Halifax for inspection.<a class="footnote-ref" id="fnref:25" href="#fn:25">25</a>

<h2 id="disaster">Disaster</h2>

The Norwegian ship <a href="/facts/SS_Imo/hTsnyf0c">SS Imo</a> had sailed from the Netherlands en route to New York to take on relief supplies for Belgium, under the command of Haakon From.<a class="footnote-ref" id="fnref:26" href="#fn:26">26</a> The ship arrived in Halifax on 3 December for neutral inspection and spent two days in Bedford Basin awaiting refuelling supplies.<a class="footnote-ref" id="fnref:27" href="#fn:27">27</a> Though she had been given clearance to leave the port on 5 December, Imo's departure was delayed because her coal load did not arrive until late that afternoon. The loading of fuel was not completed until after the anti-submarine nets had been raised for the night. Therefore, the vessel could not depart until the next morning.<a class="footnote-ref" id="fnref:28" href="#fn:28">28</a><a class="footnote-ref" id="fnref:29" href="#fn:29">29</a>
The French cargo ship <a href="/facts/SS_Mont-Blanc/wDCzYMV8">SS Mont-Blanc</a> arrived from New York late on 5 December, under the command of Aimé Le Medec.<a class="footnote-ref" id="fnref:30" href="#fn:30">30</a> The vessel was fully loaded with the explosives <a href="/facts/Trinitrotoluene/sADUt6nC">TNT</a> and <a href="/facts/Picric_acid/QUCqY6YW">picric acid</a>, the highly flammable fuel <a href="/facts/Benzole/Hy5KXjqc">benzol</a> and <a href="/facts/Guncotton/5NoD5eTm">guncotton</a>.<a class="footnote-ref" id="fnref:31" href="#fn:31">31</a> She intended to join a slow convoy gathering in Bedford Basin readying to depart for Europe but was too late to enter the harbour before the nets were raised.<a class="footnote-ref" id="fnref:32" href="#fn:32">32</a> Ships carrying dangerous cargo were not allowed into the harbour before the war, but the risks posed by German submarines had resulted in a relaxation of regulations.<a class="footnote-ref" id="fnref:33" href="#fn:33">33</a>
Navigating into or out of Bedford Basin required passage through a strait called the Narrows. Ships were expected to keep close to the <a href="/facts/Lateral_mark/KadxIKgp">side of the channel</a> situated on their <a href="/facts/Port_and_starboard/jCqXG8wA">starboard</a> ("right"), and pass oncoming vessels "port to port", that is to keep them on their "left" side.<a class="footnote-ref" id="fnref:34" href="#fn:34">34</a> Ships were restricted to a speed of 5 <a href="/facts/Knot_(unit)/Sho0TF2y">knots</a> (9.3 km/h; 5.8 mph) within the harbour.<a class="footnote-ref" id="fnref:35" href="#fn:35">35</a>

<h3>Collision and fire</h3>

Imo was granted clearance to leave <a href="/facts/Bedford_Basin/n3M9HkvR">Bedford Basin</a> by signals from the guard ship <a href="/facts/CSS_Acadia/wsjGR68u">HMCS Acadia</a> at approximately 7:30 on the morning of 6 December,<a class="footnote-ref" id="fnref:36" href="#fn:36">36</a> with Pilot William Hayes on board. The ship entered the Narrows well above the harbour's speed limit in an attempt to make up for the delay experienced in loading her coal.<a class="footnote-ref" id="fnref:37" href="#fn:37">37</a> Imo met American <a href="/facts/Tramp_trade/m2RWcydq">tramp steamer</a> SS Clara being piloted up the wrong (western) side of the harbour.<a class="footnote-ref" id="fnref:38" href="#fn:38">38</a> The pilots agreed to pass starboard-to-starboard.<a class="footnote-ref" id="fnref:39" href="#fn:39">39</a> Soon afterwards, Imo was forced to head even further towards the Dartmouth shore after passing the <a href="/facts/Tugboat/GJN1wj1d">tugboat</a> <a href="/facts/Stella_Maris_(ship)/S2yLon1X">Stella Maris</a>, which was travelling up the harbour to Bedford Basin near mid-channel. Horatio Brannen, the captain of Stella Maris, saw Imo approaching at excessive speed and ordered his ship closer to the western shore to avoid an accident.<a class="footnote-ref" id="fnref:40" href="#fn:40">40</a><a class="footnote-ref" id="fnref:41" href="#fn:41">41</a><a class="footnote-ref" id="fnref:42" href="#fn:42">42</a>
Francis Mackey, an experienced harbour pilot, had boarded Mont-Blanc on the evening of 5 December 1917; he had asked about "special protections" such as a guard ship, given Mont-Blanc's cargo, but no protections were put in place.<a class="footnote-ref" id="fnref:43" href="#fn:43">43</a> Mont-Blanc started moving at 7:30 am on 6 December and was the second ship to enter the harbour as the anti-submarine net between <a href="/facts/Georges_Island_(Nova_Scotia)/cmNhEBd1">Georges Island</a> and <a href="/facts/Pier_21/PIYVI4x3">Pier 21</a> opened for the morning.<a class="footnote-ref" id="fnref:44" href="#fn:44">44</a> Mont-Blanc headed towards Bedford Basin on the Dartmouth side of the harbour.<a class="footnote-ref" id="fnref:45" href="#fn:45">45</a><a class="footnote-ref" id="fnref:46" href="#fn:46">46</a><a class="footnote-ref" id="fnref:47" href="#fn:47">47</a> Mackey kept his eye on the ferry traffic between Halifax and Dartmouth and other small boats in the area.<a class="footnote-ref" id="fnref:48" href="#fn:48">48</a> He first spotted Imo when she was about 1.21 kilometres (0.75 mi) away and became concerned as her path appeared to be heading towards his ship's starboard side, as if to cut him off. Mackey gave a short blast of his ship's signal whistle to indicate that he had the right of way but was met with two short blasts from Imo, indicating that the approaching vessel would not yield its position.<a class="footnote-ref" id="fnref:49" href="#fn:49">49</a><a class="footnote-ref" id="fnref:50" href="#fn:50">50</a><a class="footnote-ref" id="fnref:51" href="#fn:51">51</a> The captain ordered Mont-Blanc to halt her engines and angle slightly to starboard, closer to the Dartmouth side of the Narrows. He let out another single blast of his whistle, hoping the other vessel would likewise move to starboard but was again met with a double-blast.<a class="footnote-ref" id="fnref:52" href="#fn:52">52</a>
Sailors on nearby ships heard the series of signals and, realizing that a collision was imminent, gathered to watch as Imo bore down on Mont-Blanc.<a class="footnote-ref" id="fnref:53" href="#fn:53">53</a> Both ships had cut their engines by this point, but their momentum carried them towards each other at slow speed. Unable to ground his ship for fear of a shock that would set off his explosive cargo, Mackey ordered Mont-Blanc to steer hard to port (starboard helm) and crossed the bow of Imo in a last-second bid to avoid a collision. The two ships were almost parallel to each other, when Imo suddenly sent out three signal blasts, indicating the ship was reversing its engines. The combination of the cargoless ship's height in the water and the <a href="/facts/Propeller_walk/jaFcaRfS">transverse thrust</a> of her right-hand propeller caused the ship's head to swing into Mont-Blanc. Imo's prow pushed into the No. 1 hold of Mont Blanc, on her starboard side.<a class="footnote-ref" id="fnref:54" href="#fn:54">54</a><a class="footnote-ref" id="fnref:55" href="#fn:55">55</a>
The collision occurred at 8:45 am.<a class="footnote-ref" id="fnref:56" href="#fn:56">56</a> The damage to Mont Blanc was not severe, but barrels of deck cargo toppled and broke open. This flooded the deck with benzol that quickly flowed into the hold. As Imo's engines kicked in, she disengaged, which created sparks inside Mont-Blanc's hull. These ignited the vapours from the benzol. A fire started at the water line and travelled quickly up the side of the ship. Surrounded by thick black smoke, and fearing she would explode almost immediately, the captain ordered the crew to abandon ship.<a class="footnote-ref" id="fnref:57" href="#fn:57">57</a><a class="footnote-ref" id="fnref:58" href="#fn:58">58</a> A growing number of Halifax citizens gathered on the street or stood at the windows of their homes or businesses to watch the spectacular fire.<a class="footnote-ref" id="fnref:59" href="#fn:59">59</a> The frantic crew of Mont-Blanc shouted from their two lifeboats to some of the other vessels that their ship was about to explode, but they could not be heard above the noise and confusion.<a class="footnote-ref" id="fnref:60" href="#fn:60">60</a> As the lifeboats made their way across the harbour to the Dartmouth shore, the abandoned ship continued to drift and beached herself at Pier 6 near the foot of Richmond street.<a class="footnote-ref" id="fnref:61" href="#fn:61">61</a>
Towing two <a href="/facts/Scow/EYBCXlHP">scows</a> at the time of the collision,<a class="footnote-ref" id="fnref:62" href="#fn:62">62</a> Stella Maris responded immediately to the fire, anchoring the barges and steaming back towards Pier 6 to spray the burning ship with their fire hose.<a class="footnote-ref" id="fnref:63" href="#fn:63">63</a> The tug's captain, Horatio H. Brannen, and his crew realized that the fire was too intense for their single hose and backed off from the burning Mont Blanc. They were approached by a <a href="/facts/Whaleboat/z3r1dWAl">whaler</a> from <a href="/facts/HMS_Highflyer_(1898)/3QblogE1">HMS Highflyer</a> and later a steam <a href="/facts/Pinnace_(ship%27s_boat)/f1CDqh2l">pinnace</a> belonging to <a href="/facts/HMS_Niobe_(1897)/jtNpH1rL">HMCS Niobe</a>. Captain Brannen and Albert Mattison of Niobe agreed to secure a line to the French ship's stern so as to pull it away from the pier to avoid setting it on fire. The five-inch (125 mm) <a href="/facts/Hawser/9y0v2ukU">hawser</a> initially produced was deemed too small and orders for a ten-inch (250 mm) hawser came down. It was at this point that the blast occurred.<a class="footnote-ref" id="fnref:64" href="#fn:64">64</a>

<h3>Explosion</h3>

At 9:04:35 am the out-of-control fire on board Mont-Blanc set off her cargo of high explosives.<a class="footnote-ref" id="fnref:65" href="#fn:65">65</a> The ship was completely blown apart and a powerful <a href="/facts/Blast_wave/aDgFJWLm">blast wave</a> radiated away from the explosion initially at more than 1,000 metres (3,300 ft) per second. Temperatures of 5,000 °C (9,000 °F) and pressures of thousands of atmospheres accompanied the moment of detonation at the centre of the explosion.<a class="footnote-ref" id="fnref:66" href="#fn:66">66</a><a class="footnote-ref" id="fnref:67" href="#fn:67">67</a> White-hot shards of iron fell down upon Halifax and Dartmouth.<a class="footnote-ref" id="fnref:68" href="#fn:68">68</a>
A cloud of white smoke rose to at least 3,600 metres (11,800 ft).<a class="footnote-ref" id="fnref:69" href="#fn:69">69</a> The blast was felt as far away as <a href="/facts/Cape_Breton_Island/PSAWLQL0">Cape Breton</a> (207 kilometres or 129 miles) and <a href="/facts/Prince_Edward_Island/lgY4nUa2">Prince Edward Island</a> (180 kilometres or 110 miles).<a class="footnote-ref" id="fnref:70" href="#fn:70">70</a><a class="footnote-ref" id="fnref:71" href="#fn:71">71</a> An area of over 1.6 square kilometres (400 acres) was completely destroyed by the explosion,<a class="footnote-ref" id="fnref:72" href="#fn:72">72</a> and the harbour floor was momentarily exposed by the volume of water that was displaced. A tsunami was formed by water surging in to fill the void;<a class="footnote-ref" id="fnref:73" href="#fn:73">73</a> it rose as high as 18 metres (60 ft) above the high-water mark on the Halifax side of the harbour.<a class="footnote-ref" id="fnref:74" href="#fn:74">74</a> Imo was carried onto the shore at Dartmouth by the tsunami.<a class="footnote-ref" id="fnref:75" href="#fn:75">75</a> The blast killed all but one on the whaler, everyone on the pinnace and 21 of the 26 men on Stella Maris; she ended up on the Dartmouth shore, severely damaged. The captain's son, First Mate Walter Brannen, who had been thrown into the hold by the blast, survived, as did four others.<a class="footnote-ref" id="fnref:76" href="#fn:76">76</a> All but one of Mont-Blanc's crew members survived.<a class="footnote-ref" id="fnref:77" href="#fn:77">77</a>
The blast instantly killed more than 1,600 people and injured an additional 9,000, more than 300 of whom later died.<a class="footnote-ref" id="fnref:78" href="#fn:78">78</a> It destroyed or badly damaged every building within a 2.6-kilometre (1.6 mi) radius, over 12,000 in total.<a class="footnote-ref" id="fnref:79" href="#fn:79">79</a> Hundreds of people who had been watching the fire from their homes were blinded when the blast wave shattered the windows in front of them.<a class="footnote-ref" id="fnref:80" href="#fn:80">80</a> Overturned stoves and lamps started fires throughout Halifax,<a class="footnote-ref" id="fnref:81" href="#fn:81">81</a> particularly in the <a href="/facts/North_End,_Halifax/YkN6cqTD">North End</a>, where entire city blocks burned, trapping residents inside their houses. Firefighter Billy Wells, who was thrown away from the explosion and had his clothes torn from his body, described the devastation survivors faced: "The sight was awful, with people hanging out of windows dead. Some with their heads missing, and some thrown onto the overhead telegraph wires." He was the only member of the eight-man crew of the fire engine Patricia to survive.<a class="footnote-ref" id="fnref:82" href="#fn:82">82</a>
Large brick and stone factories near Pier 6, such as the Acadia Sugar Refinery, disappeared into unrecognizable heaps of rubble, killing most of their workers.<a class="footnote-ref" id="fnref:83" href="#fn:83">83</a> The <a href="/facts/Nova_Scotia_Cotton_Manufacturing_Company/kbmoaQh2">Nova Scotia cotton mill</a> located 1.5 km (0.93 mile) from the blast was destroyed by fire and the collapse of its concrete floors.<a class="footnote-ref" id="fnref:84" href="#fn:84">84</a> The <a href="/facts/Royal_Naval_College_of_Canada/GmYcpnxU">Royal Naval College of Canada</a> building was badly damaged, and several cadets and instructors maimed.<a class="footnote-ref" id="fnref:85" href="#fn:85">85</a> The Richmond Railway Yards and station were destroyed, killing 55 railway workers and destroying and damaging over 500 railway cars. The <a href="/facts/North_Street_Station_(Halifax)/MUlCs0kM">North Street Station</a>, one of the busiest in Canada, was badly damaged.<a class="footnote-ref" id="fnref:86" href="#fn:86">86</a>

The death toll could have been worse had it not been for the self-sacrifice of an Intercolonial Railway dispatcher, <a href="/facts/Vince_Coleman_(train_dispatcher)/42GkmUIX">Patrick Vincent (Vince) Coleman</a>, operating at the railyard about 230 metres (750 ft) from Pier 6, where the explosion occurred. He and his co-worker, William Lovett, learned of the dangerous cargo aboard the burning Mont-Blanc from a sailor and began to flee. Coleman remembered that an incoming passenger train from <a href="/facts/Saint_John,_New_Brunswick/GKg2aueF">Saint John, New Brunswick</a>, was due to arrive at the railyard within minutes. He returned to his post alone and continued to send out urgent telegraph messages to stop the train. Several variations of the message have been reported, among them this from the <a href="/facts/Maritime_Museum_of_the_Atlantic/8gfs9X4a">Maritime Museum of the Atlantic</a>: "Hold up the train. Ammunition ship afire in harbor making for Pier 6 and will explode. Guess this will be my last message. Good-bye boys." Coleman's message was responsible for bringing all incoming trains around Halifax to a halt. It was heard by other stations all along the Intercolonial Railway, helping railway officials to respond immediately.<a class="footnote-ref" id="fnref:87" href="#fn:87">87</a><a class="footnote-ref" id="fnref:88" href="#fn:88">88</a> Passenger Train No. 10, the overnight train from Saint John, is believed to have heeded the warning and stopped a safe distance from the blast at <a href="/facts/Rockingham,_Nova_Scotia/H9mcnh89">Rockingham</a>, saving the lives of about 300 railway passengers. Coleman was killed at his post.<a class="footnote-ref" id="fnref:89" href="#fn:89">89</a>

<h2 id="rescue-efforts">Rescue efforts</h2>

First rescue efforts came from surviving neighbours and co-workers who pulled and dug out victims from buildings. The initial informal response was soon joined by surviving policemen, firefighters and military personnel who began to arrive, as did anyone with a working vehicle; cars, trucks and delivery wagons of all kinds were enlisted to collect the wounded.<a class="footnote-ref" id="fnref:90" href="#fn:90">90</a><a class="footnote-ref" id="fnref:91" href="#fn:91">91</a><a class="footnote-ref" id="fnref:92" href="#fn:92">92</a><a class="footnote-ref" id="fnref:93" href="#fn:93">93</a> A flood of victims soon began to arrive at the city's hospitals, which were quickly overwhelmed.<a class="footnote-ref" id="fnref:94" href="#fn:94">94</a> The new military hospital, Camp Hill, admitted approximately 1,400 victims on 6 December.<a class="footnote-ref" id="fnref:95" href="#fn:95">95</a>
Firefighters were among the first to respond to the disaster, rushing to Mont-Blanc to attempt to extinguish the blaze before the explosion even occurred.<a class="footnote-ref" id="fnref:96" href="#fn:96">96</a> They also played a role after the blast, with fire companies arriving to assist from across Halifax, and by the end of the day from as far away as <a href="/facts/Amherst,_Nova_Scotia/nqEyAUTw">Amherst, Nova Scotia</a>, (200 kilometres or 120 miles) and <a href="/facts/Moncton,_New_Brunswick/l4oNygPl">Moncton, New Brunswick</a>, (260 kilometres or 160 miles) on relief trains.<a class="footnote-ref" id="fnref:97" href="#fn:97">97</a><a class="footnote-ref" id="fnref:98" href="#fn:98">98</a> <a href="/facts/Halifax_Regional_Fire_and_Emergency/PuMJSgJs">Halifax Fire Department</a>'s West Street Station 2 was the first to arrive at Pier 6 with the crew of Patricia, the first motorized fire engine in Canada. In the final moments before the explosion, hoses were being unrolled as the fire spread to the docks. Nine members of the Halifax Fire Department lost their lives performing their duty that day.<a class="footnote-ref" id="fnref:99" href="#fn:99">99</a><a class="footnote-ref" id="fnref:100" href="#fn:100">100</a>
Royal Navy cruisers in port sent some of the first organized rescue parties ashore. HMS Highflyer, along with the <a href="/facts/Armed_merchant_cruiser/5KjaDHf8">armed merchant cruisers</a> HMS Changuinola, HMS Knight Templar and <a href="/facts/HMS_Calgarian/B90Quv3a">HMS Calgarian</a>, sent boats ashore with rescue parties and medical personnel and soon began to take wounded aboard.<a class="footnote-ref" id="fnref:101" href="#fn:101">101</a> A <a href="/facts/United_States_Coast_Guard/6d7SWTP9">US Coast Guard</a> cutter, <a href="/facts/USRC_Morrill/dlkDozBb">USRC Morrill</a>, also sent a rescue party ashore.<a class="footnote-ref" id="fnref:102" href="#fn:102">102</a> Out at sea, the American cruiser <a href="/facts/USS_Tacoma_(CL-20)/89m1MWXJ">USS Tacoma</a> and armed merchant cruiser <a href="/facts/SS_Kronprinz_Wilhelm/njMhJ3Bk">USS Von Steuben</a> (formerly SS Kronprinz Wilhelm) were passing Halifax en route to the United States. Tacoma was rocked so severely by the blast wave that her crew went to <a href="/facts/General_quarters/w8o9hDoq">general quarters</a>.<a class="footnote-ref" id="fnref:103" href="#fn:103">103</a> Spotting the large and rising column of smoke, Tacoma altered course and arrived to assist rescue at 2 pm. Von Steuben arrived a half-hour later.<a class="footnote-ref" id="fnref:104" href="#fn:104">104</a> The American steamship Old Colony, docked in Halifax for repairs, suffered little damage and was quickly converted to serve as a hospital ship, staffed by doctors and orderlies from the British and American navy vessels in the harbour.<a class="footnote-ref" id="fnref:105" href="#fn:105">105</a>
Dazed survivors immediately feared that the explosion was the result of a bomb dropped from a German plane.<a class="footnote-ref" id="fnref:106" href="#fn:106">106</a> Troops at gun batteries and barracks immediately turned out in case the city was under attack, but within an hour switched from defence to rescue roles as the cause and location of the explosion were determined. All available troops were called in from harbour fortifications and barracks to the North End to rescue survivors and provide transport to the city's hospitals, including the two army hospitals in the city.<a class="footnote-ref" id="fnref:107" href="#fn:107">107</a>
Adding to the chaos were fears of a potential second explosion. A cloud of steam shot out of ventilators at the ammunition magazine at Wellington Barracks as naval personnel extinguished a fire by the magazine. The fire was quickly put out; the cloud was seen from blocks away and quickly led to rumours that another explosion was imminent.<a class="footnote-ref" id="fnref:108" href="#fn:108">108</a> Uniformed officers ordered everyone away from the area.<a class="footnote-ref" id="fnref:109" href="#fn:109">109</a> As the rumour spread across the city, many families fled their homes. The confusion hampered efforts for over two hours until fears were dispelled by about noon.<a class="footnote-ref" id="fnref:110" href="#fn:110">110</a><a class="footnote-ref" id="fnref:111" href="#fn:111">111</a> Many rescuers ignored the evacuation, and naval rescue parties continued working uninterrupted at the harbour.<a class="footnote-ref" id="fnref:112" href="#fn:112">112</a><a class="footnote-ref" id="fnref:113" href="#fn:113">113</a>
Surviving railway workers in the railyards at the heart of the disaster carried out rescue work, pulling people from the harbour and from under debris. The overnight train from Saint John was just approaching the city when hit by the blast but was only slightly damaged. It continued into Richmond until the track was blocked by wreckage. Passengers and soldiers aboard used the emergency tools from the train to dig people out of houses and bandaged them with sheets from the sleeping cars. The train was loaded with injured and left the city at 1:30 with a doctor aboard, to evacuate the wounded to <a href="/facts/Truro,_Nova_Scotia/6zjyzTdd">Truro</a>.<a class="footnote-ref" id="fnref:114" href="#fn:114">114</a><a class="footnote-ref" id="fnref:115" href="#fn:115">115</a>
Led by <a href="/facts/Lieutenant_Governor_of_Nova_Scotia/yHkTznu7">Lieutenant Governor</a> <a href="/facts/MacCallum_Grant/dQLo0aLd">MacCallum Grant</a>, leading citizens formed the Halifax Relief Commission at around noon. The committee organized members in charge of organizing medical relief for both Halifax and Dartmouth, supplying transportation, food and shelter, and covering medical and funeral costs for victims.<a class="footnote-ref" id="fnref:116" href="#fn:116">116</a><a class="footnote-ref" id="fnref:117" href="#fn:117">117</a> The commission would continue until 1976, participating in reconstruction and relief efforts and later distributing pensions to survivors.<a class="footnote-ref" id="fnref:118" href="#fn:118">118</a><a class="footnote-ref" id="fnref:119" href="#fn:119">119</a> Men and women turned out to serve as everything from hospital aides to shelter staff, while children contributed to the relief effort by carrying messages from site to site.<a class="footnote-ref" id="fnref:120" href="#fn:120">120</a> Community facilities like the <a href="/facts/YMCA/rfcxcX60">Young Men's Christian Association (YMCA)</a> were rapidly converted to emergency hospital facilities with medical students providing care.<a class="footnote-ref" id="fnref:121" href="#fn:121">121</a>
Rescue trains were dispatched from across Atlantic Canada, as well as the northeastern United States. The first left Truro around 10 am carrying medical personnel and supplies, arrived in Halifax by noon and returned to Truro with the wounded and homeless by 3 pm. The track had become impassable after Rockingham, on the western edge of Bedford Basin. To reach the wounded, rescue personnel had to walk through parts of the devastated city until they reached a point where the military had begun to clear the streets.<a class="footnote-ref" id="fnref:122" href="#fn:122">122</a> By nightfall, a dozen trains had reached Halifax from the Nova Scotian towns of Truro, <a href="/facts/Kentville,_Nova_Scotia/GRmNvf8C">Kentville</a>, Amherst, <a href="/facts/Stellarton,_Nova_Scotia/HyY6fEuf">Stellarton</a>, <a href="/facts/Pictou/GB80Y4kF">Pictou</a>, and <a href="/facts/Sydney,_Nova_Scotia/G8nS6l65">Sydney</a> and from New Brunswick, including the town of <a href="/facts/Sackville,_New_Brunswick/UBaGKmYh">Sackville</a>, and the cities of <a href="/facts/Moncton/l4oNygPl">Moncton</a> and Saint John.<a class="footnote-ref" id="fnref:123" href="#fn:123">123</a><a class="footnote-ref" id="fnref:124" href="#fn:124">124</a>
Relief efforts were hampered the following day by a <a href="/facts/Blizzard/vSKo2dp8">blizzard</a> that blanketed Halifax with 16 inches (41 cm) of heavy snow. Trains en route from other parts of Canada and from the United States were stalled in snowdrifts, and telegraph lines that had been hastily repaired following the explosion were again knocked down. Halifax was isolated by the storm, and while rescue committees were forced to suspend the search for survivors, the storm also aided efforts to put out fires throughout the city.<a class="footnote-ref" id="fnref:125" href="#fn:125">125</a><a class="footnote-ref" id="fnref:126" href="#fn:126">126</a>

<h2 id="destruction-and-loss-of-life">Destruction and loss of life</h2>

The exact number killed by the disaster is unknown. The Halifax Explosion Remembrance Book, an official database of the <a href="/facts/Nova_Scotia_Archives_and_Records_Management/dgcXTFXj">Nova Scotia Archives and Records Management</a>, identified 1,782 victims.<a class="footnote-ref" id="fnref:127" href="#fn:127">127</a> As many as 1,600 people died immediately in the blast, tsunami, and collapse of buildings. The last body, a caretaker killed at the Exhibition Grounds, was not recovered until summer 1919.<a class="footnote-ref" id="fnref:128" href="#fn:128">128</a> An additional 9,000 were injured.<a class="footnote-ref" id="fnref:129" href="#fn:129">129</a> 1,630 homes were destroyed in the explosion and fires, and another 12,000 damaged; roughly 6,000 people were left homeless and 25,000 had insufficient shelter.<a class="footnote-ref" id="fnref:130" href="#fn:130">130</a><a class="footnote-ref" id="fnref:131" href="#fn:131">131</a> The city's industrial sector was in large part gone, with many workers among the casualties and the dockyard heavily damaged.<a class="footnote-ref" id="fnref:132" href="#fn:132">132</a>
A mortuary committee chaired by Alderman R. B. Coldwell was quickly formed at <a href="/facts/Halifax_City_Hall/VpGPPIcH">Halifax City Hall</a> on the morning of the disaster. The Chebucto Road School (now the <a href="/facts/Maritime_Conservatory_of_Performing_Arts/2sCF07yd">Maritime Conservatory of Performing Arts</a>) in <a href="/facts/West_End,_Halifax/WoezxBhA">Halifax's west end</a> was chosen as a central morgue.<a class="footnote-ref" id="fnref:133" href="#fn:133">133</a> A company of the <a href="/facts/Royal_Canadian_Engineers/FJsU3tjx">Royal Canadian Engineers</a> (RCE) repaired and converted the basement of the school to serve as a morgue and classrooms to serve as offices for the Halifax coroner. Trucks and wagons soon began to arrive with bodies.<a class="footnote-ref" id="fnref:134" href="#fn:134">134</a> Arthur S. Barnstead took over from Coldwell as the morgue went into operation and implemented a system based on the one his father, <a href="/facts/John_Henry_Barnstead/LrnFhhGX">John Henry Barnstead</a>, developed to catalogue the dead<a class="footnote-ref" id="fnref:135" href="#fn:135">135</a> in the aftermath of the <a href="/facts/Titanic/loD4esxz">Titanic</a> disaster of 1912.<a class="footnote-ref" id="fnref:136" href="#fn:136">136</a> Many of the wounds inflicted by the blast were permanently debilitating, such as those caused by flying glass or by the flash of the explosion. Thousands of people had stopped to watch the ship burning in the harbour, many from inside buildings, leaving them directly in the path of glass fragments from shattered windows.<a class="footnote-ref" id="fnref:137" href="#fn:137">137</a> According to an article in the <a href="/facts/British_Journal_of_Ophthalmology/Rvo2CF4R">British Journal of Ophthalmology</a>, ophthalmologists responding to the disaster performed 249 <a href="/facts/Enucleation_of_the_eye/lDuVKfsx">enucleations</a>; 16 people had both eyes removed.<a class="footnote-ref" id="fnref:138" href="#fn:138">138</a>
An estimated CA$35 million in damage resulted (CA$696 million today).<a class="footnote-ref" id="fnref:139" href="#fn:139">139</a> About $30 million in financial aid was raised from various sources,<a class="footnote-ref" id="fnref:140" href="#fn:140">140</a> including $18 million from the federal government, over $4 million from the British government, and $750,000 from the Commonwealth of <a href="/facts/Massachusetts/9uumCbFI">Massachusetts</a>.<a class="footnote-ref" id="fnref:141" href="#fn:141">141</a>

<h3>Dartmouth</h3>
Dartmouth was not as densely populated as Halifax and was separated from the blast by the width of the harbour, but still suffered heavy damage. Almost 100 people were estimated to have died on the Dartmouth side. Windows were shattered and many buildings were damaged or destroyed, including the <a href="/facts/Oland_Brewery/0ksP4FWv">Oland Brewery</a> and parts of the Starr Manufacturing Company.<a class="footnote-ref" id="fnref:142" href="#fn:142">142</a> <a href="/facts/Nova_Scotia_Hospital/mjfwT2DW">Nova Scotia Hospital</a> was the only hospital in Dartmouth and many of the victims were treated there.<a class="footnote-ref" id="fnref:143" href="#fn:143">143</a>

<h3>Mi'kmaq settlement</h3>
There were small enclaves of <a href="/facts/Mi%27kmaq/THH8x1Ek">Mi'kmaq</a> in and around the coves of Bedford Basin on the Dartmouth shore. Directly opposite to Pier 9 on the Halifax side sat a community in <a href="/facts/Tufts_Cove,_Nova_Scotia/K2qsdFPt">Tufts Cove</a> which included the Mi'kmaq community of Turtle Grove. In the years and months preceding the explosion, the <a href="/facts/Indigenous_and_Northern_Affairs_Canada/2uUx6Xcu">Department of Indian Affairs</a> had been actively trying to force the Mi'kmaq to give up their land and move to a reserve, but this had not occurred by the time of the explosion.<a class="footnote-ref" id="fnref:144" href="#fn:144">144</a><a class="footnote-ref" id="fnref:145" href="#fn:145">145</a> Turtle Grove was close to the centre of the blast and the physical structures of the settlement were obliterated by the explosion and tsunami.<a class="footnote-ref" id="fnref:146" href="#fn:146">146</a> A precise Mi'kmaq death toll is unknown as the Department of Indian Affairs and census records for the community were incomplete. Nine bodies were recovered from Turtle Grove and there were eleven known survivors.<a class="footnote-ref" id="fnref:147" href="#fn:147">147</a> The Halifax Remembrance Book lists 16 members of the Tufts Cove Community as dead; not all the dead listed as in Tufts Cove were Indigenous.<a class="footnote-ref" id="fnref:148" href="#fn:148">148</a> The Turtle Grove settlement was not rebuilt in the wake of the disaster.<a class="footnote-ref" id="fnref:149" href="#fn:149">149</a> Survivors were housed in a racially segregated building under generally poor conditions and most were eventually dispersed around Nova Scotia.<a class="footnote-ref" id="fnref:150" href="#fn:150">150</a>

<h3>Africville</h3>
The <a href="/facts/Black_people/khyfdI6h">Black</a> community of <a href="/facts/Africville/GgB5uJ1B">Africville</a>, on the southern shores of Bedford Basin adjacent to the <a href="/facts/Halifax_Peninsula/J4xxhA58">Halifax Peninsula</a>, was spared the direct force of the blast by the shadow effect of the raised ground to the south.<a class="footnote-ref" id="fnref:151" href="#fn:151">151</a><a class="footnote-ref" id="fnref:152" href="#fn:152">152</a> However, Africville's small and frail homes were heavily damaged by the explosion.<a class="footnote-ref" id="fnref:153" href="#fn:153">153</a> Families recorded the deaths of five residents.<a class="footnote-ref" id="fnref:154" href="#fn:154">154</a> A combination of persistent racism and a growing conviction that Africville should be demolished to make way for industrial development resulted in the people of Africville receiving no police or fire protection; they had to make do without water mains and sewer lines, despite paying city taxes.<a class="footnote-ref" id="fnref:155" href="#fn:155">155</a> Africville received little of the donated relief funds and none of the progressive reconstruction invested in other parts of the city after the explosion.<a class="footnote-ref" id="fnref:156" href="#fn:156">156</a><a class="footnote-ref" id="fnref:157" href="#fn:157">157</a>

<h2 id="investigation">Investigation</h2>
Many people in Halifax first thought the explosion to be the result of a German attack.<a class="footnote-ref" id="fnref:158" href="#fn:158">158</a> The <a href="/facts/The_Chronicle_Herald/VXm1tWT9">Halifax Herald</a> continued to propagate this belief for some time, reporting, for example, that Germans had mocked victims of the explosion.<a class="footnote-ref" id="fnref:159" href="#fn:159">159</a> While John Johansen, the Norwegian helmsman of Imo, was being treated for serious injuries sustained during the explosion, it was reported to the military police that he had been behaving suspiciously. Johansen was arrested on suspicions of being a German spy when a search turned up a letter on his person, supposedly written in German.<a class="footnote-ref" id="fnref:160" href="#fn:160">160</a> It turned out that the letter was actually written in Norwegian.<a class="footnote-ref" id="fnref:161" href="#fn:161">161</a> Immediately following the explosion, most of the German survivors in Halifax had been rounded up and imprisoned.<a class="footnote-ref" id="fnref:162" href="#fn:162">162</a><a class="footnote-ref" id="fnref:163" href="#fn:163">163</a> Eventually the fear dissipated as the real cause of the explosion became known, although rumours of German involvement persisted.<a class="footnote-ref" id="fnref:164" href="#fn:164">164</a>
A <a href="/facts/Judicial_inquiry/dmg1yN5S">judicial inquiry</a> known as the Wreck Commissioner's Inquiry was formed to investigate the causes of the collision. Proceedings began at the <a href="/facts/Halifax_Court_House/TvKS5rJt">Halifax Court House</a> on 13 December 1917, presided over by Justice <a href="/facts/Arthur_Drysdale/FwLYXUbj">Arthur Drysdale</a>.<a class="footnote-ref" id="fnref:165" href="#fn:165">165</a> The inquiry's report of 4 February 1918 blamed Mont-Blanc's <a href="/facts/Captain_(naval)/EeuMbyo5">captain</a>, Aimé Le Médec, the ship's <a href="/facts/Maritime_pilot/awYfasC4">pilot</a>, Francis Mackey, and Commander F. Evan Wyatt, the Royal Canadian Navy's chief examining officer in charge of the harbour, gates and anti-submarine defences, for causing the collision.<a class="footnote-ref" id="fnref:166" href="#fn:166">166</a> Drysdale agreed with Dominion Wreck Commissioner L. A. Demers' opinion that "it was the Mont-Blanc's responsibility alone to ensure that she avoided a collision at all costs" given her cargo;<a class="footnote-ref" id="fnref:167" href="#fn:167">167</a> he was likely influenced by local opinion, which was strongly anti-French, as well as by the "street fighter" style of argumentation used by Imo lawyer Charles Burchell.<a class="footnote-ref" id="fnref:168" href="#fn:168">168</a> According to Crown counsel W. A. Henry, this was "a great surprise to most people", who had expected the Imo to be blamed for being on the wrong side of the channel.<a class="footnote-ref" id="fnref:169" href="#fn:169">169</a> All three men were charged with <a href="/facts/Manslaughter/NGPBCB66">manslaughter</a> and <a href="/facts/Criminal_negligence/qWfCNmV2">criminal negligence</a> at a preliminary hearing heard by <a href="/facts/Stipendiary_Magistrate/jGqgJbdn">Stipendiary Magistrate</a> Richard A. McLeod, and bound over for trial. A <a href="/facts/Nova_Scotia_Supreme_Court/2cj62Ujy">Nova Scotia Supreme Court</a> justice, <a href="/facts/Benjamin_Russell_(Canadian_politician)/7WnqVFee">Benjamin Russell</a>, found there was no evidence to support these charges. Mackey was discharged on a <a href="/facts/Writ/w3757hnR">writ</a> of <a href="/facts/Habeas_corpus/2tHT81Hd">habeas corpus</a> and the charges dropped. Because the pilot and the captain were arrested on the same warrant, the charges against Le Médec were also dismissed. Commander Wyatt, charged on a separate warrant, was the only one of the three who was indicted.<a class="footnote-ref" id="fnref:170" href="#fn:170">170</a> On 17 April 1918, a jury acquitted Wyatt in a trial that lasted less than a day.<a class="footnote-ref" id="fnref:171" href="#fn:171">171</a>
Drysdale oversaw the first civil litigation trial, in which the owners of the two ships sought damages from each other. His decision (27 April 1918) found Mont-Blanc entirely at fault.<a class="footnote-ref" id="fnref:172" href="#fn:172">172</a> Subsequent appeals to the <a href="/facts/Supreme_Court_of_Canada/RQJKhKzC">Supreme Court of Canada</a> (19 May 1919), and the <a href="/facts/Judicial_Committee_of_the_Privy_Council/X8bCs2mv">Judicial Committee of the Privy Council</a> in London (22 March 1920), determined Mont-Blanc and Imo were equally to blame for navigational errors that led to the collision.<a class="footnote-ref" id="fnref:173" href="#fn:173">173</a><a class="footnote-ref" id="fnref:174" href="#fn:174">174</a><a class="footnote-ref" id="fnref:175" href="#fn:175">175</a> No party was ever convicted for any crime or otherwise successfully prosecuted for any actions that precipitated the disaster.<a class="footnote-ref" id="fnref:176" href="#fn:176">176</a>

<h2 id="reconstruction">Reconstruction</h2>

Efforts began shortly after the explosion to clear debris, repair buildings, and establish temporary housing for survivors left homeless by the explosion. By late January 1918, around 5,000 were still without shelter.<a class="footnote-ref" id="fnref:177" href="#fn:177">177</a> A reconstruction committee under Colonel Robert Low constructed 832 new housing units, which were furnished by the Massachusetts-Halifax Relief Fund.<a class="footnote-ref" id="fnref:178" href="#fn:178">178</a>
Partial train service resumed from a temporary rail terminal in the city's South End on 7 December. Full service resumed on 9 December when tracks were cleared and the <a href="/facts/North_Street_Station_(Halifax)/MUlCs0kM">North Street Station</a> reopened. The <a href="/facts/Canadian_Government_Railways/xEQWf2nE">Canadian Government Railways</a> created a special unit to clear and repair railway yards as well as rebuild railway piers and the Naval Dockyard. Most piers returned to operation by late December and were repaired by January.<a class="footnote-ref" id="fnref:179" href="#fn:179">179</a>
The North End Halifax neighbourhood of Richmond bore the brunt of the explosion.<a class="footnote-ref" id="fnref:180" href="#fn:180">180</a> In 1917, Richmond was considered a working-class neighbourhood and had few paved roads. After the explosion, the Halifax Relief Commission approached the reconstruction of Richmond as an opportunity to improve and modernize the city's North End. English town planner <a href="/facts/Thomas_Adams_(architect)/rDGUVyUY">Thomas Adams</a> and Montreal architectural firm <a href="/facts/Ross_and_Macdonald/htfnNzmg">Ross and Macdonald</a> were recruited to design a new housing plan for Richmond. Adams, inspired by the Victorian <a href="/facts/Garden_city_movement/IflJvEQf">garden city movement</a>, aimed to provide public access to green spaces and to create a low-rise, low-density, and multifunctional urban neighbourhood.<a class="footnote-ref" id="fnref:181" href="#fn:181">181</a><a class="footnote-ref" id="fnref:182" href="#fn:182">182</a>
The planners designed 326 large homes that each faced a tree-lined, paved boulevard.<a class="footnote-ref" id="fnref:183" href="#fn:183">183</a> They specified that the homes be built with a new and innovative fireproof material, blocks of compressed cement called Hydrostone.<a class="footnote-ref" id="fnref:184" href="#fn:184">184</a><a class="footnote-ref" id="fnref:185" href="#fn:185">185</a> The first of these homes was occupied by March 1919,<a class="footnote-ref" id="fnref:186" href="#fn:186">186</a> just a few months before <a href="/facts/Edward_VIII/SFwwJvnW">Prince Edward, Prince of Wales</a>, visited the site on 17 August, touring many of the houses and hearing stories about the impacts of the tragedy and "of the kindness of the people who quickly came to their aid."<a class="footnote-ref" id="fnref:187" href="#fn:187">187</a> Once finished, the <a href="/facts/The_Hydrostone/vK6Fwne7">Hydrostone</a> neighbourhood consisted of homes, businesses, and parks, which helped create a new sense of community in the North End of Halifax. It has now become an upscale neighbourhood and shopping district.<a class="footnote-ref" id="fnref:188" href="#fn:188">188</a> In contrast, the equally poor and underdeveloped area of Africville was not included in reconstruction efforts.<a class="footnote-ref" id="fnref:189" href="#fn:189">189</a>
Every building in the Halifax dockyard required some degree of rebuilding, as did HMCS Niobe and the docks themselves; all of the Royal Canadian Navy's minesweepers and patrol boats were undamaged.<a class="footnote-ref" id="fnref:190" href="#fn:190">190</a> Prime Minister <a href="/facts/Robert_Borden/58HXlvXY">Robert Borden</a> pledged that the government would be "co-operating in every way to reconstruct the Port of Halifax: this was of utmost importance to the Empire".<a class="footnote-ref" id="fnref:191" href="#fn:191">191</a> Captain Symington of USS Tacoma speculated that the port would not be operational for months,<a class="footnote-ref" id="fnref:192" href="#fn:192">192</a> but a convoy departed on 11 December and dockyard operations resumed before Christmas.<a class="footnote-ref" id="fnref:193" href="#fn:193">193</a>

The Halifax Explosion was one of the <a href="/facts/Largest_artificial_non-nuclear_explosions/DXj8nBto">largest artificial non-nuclear explosions</a>. An extensive comparison of 130 major explosions by Halifax historian Jay White in 1994 concluded that it "remains unchallenged in overall magnitude as long as five criteria are considered together: number of casualties, force of blast, radius of devastation, quantity of explosive material, and total value of property destroyed."<a class="footnote-ref" id="fnref:194" href="#fn:194">194</a><a class="footnote-ref" id="fnref:195" href="#fn:195">195</a> For many years afterward, the Halifax Explosion was the standard by which all large blasts were measured. For instance, in its report on the <a href="/facts/Atomic_bombings_of_Hiroshima_and_Nagasaki/fRpj8aJA">atomic bombing of Hiroshima</a>, <a href="/facts/Time_(magazine)/N4FXc99l">Time</a> wrote that the explosive power of the <a href="/facts/Little_Boy/4XAsA7xT">Little Boy</a> bomb was seven times that of the Halifax Explosion.<a class="footnote-ref" id="fnref:196" href="#fn:196">196</a>
The many eye injuries resulting from the disaster led to better understanding of how to care for damaged eyes, and "with the recently formed <a href="/facts/Canadian_National_Institute_for_the_Blind/hSKDGDTe">Canadian National Institute for the Blind</a>, Halifax became internationally known as a centre for care for the blind", according to <a href="/facts/Dalhousie_University/yW96cGcp">Dalhousie University</a> professor Victoria Allen.<a class="footnote-ref" id="fnref:197" href="#fn:197">197</a> The lack of coordinated <a href="/facts/Pediatrics/hnkMfLeg">pediatric</a> care in such a disaster was noted by <a href="/facts/William_E._Ladd/vuWxC7VK">William Ladd</a>, a surgeon from Boston who had arrived to help. His insights from the explosion are generally credited with inspiring him to pioneer the specialty of <a href="/facts/Pediatric_surgery/h4flRUSD">pediatric surgery</a> in North America.<a class="footnote-ref" id="fnref:198" href="#fn:198">198</a><a class="footnote-ref" id="fnref:199" href="#fn:199">199</a> The Halifax Explosion inspired a series of health reforms, including around <a href="/facts/Public_sanitation/NLGqBs2T">public sanitation</a> and <a href="/facts/Maternity_care/vdh9DMEK">maternity care</a>.<a class="footnote-ref" id="fnref:200" href="#fn:200">200</a>

The event was traumatic for the whole surviving community, so the memory was largely suppressed. After the first anniversary, the city stopped commemorating the explosion for decades. The second official commemoration did not take place before the 50th anniversary in 1967, and even after that, the activities stopped again.<a class="footnote-ref" id="fnref:201" href="#fn:201">201</a> Construction began in 1964 on the <a href="/facts/Halifax_North_Memorial_Library/sQ7QMTEk">Halifax North Memorial Library</a>, designed to commemorate the victims of the explosion. The library entrance featured the first monument built to mark the explosion, the <a href="/facts/Halifax_Explosion_Memorial_Sculpture/20aGM7n6">Halifax Explosion Memorial Sculpture</a>, created by artist <a href="/facts/Jordi_Bonet/BhPwFQIp">Jordi Bonet</a>.<a class="footnote-ref" id="fnref:202" href="#fn:202">202</a> The sculpture was dismantled by the Halifax Regional Municipality in 2004.<a class="footnote-ref" id="fnref:203" href="#fn:203">203</a>
The Halifax Explosion Memorial Bells were built in 1985, relocating memorial <a href="/facts/Carillon/PkG1y4qz">carillon</a> bells from a nearby church to a large concrete sculpture on Fort Needham Hill, facing the "ground zero" area of the explosion.<a class="footnote-ref" id="fnref:204" href="#fn:204">204</a> The Bell Tower is the location of an annual civic ceremony every 6 December. A memorial at Halifax Fire Station No. 4 on Lady Hammond Road honours the firefighters killed while responding to the explosion.<a class="footnote-ref" id="fnref:205" href="#fn:205">205</a> Fragments of Mont-Blanc have been mounted as neighbourhood monuments to the explosion at Albro Lake Road in Dartmouth, at Regatta Point, and elsewhere in the area. Simple monuments mark the mass graves of explosion victims at the <a href="/facts/Fairview_Cemetery,_Halifax,_Nova_Scotia/4EbXR6oa">Fairview Lawn Cemetery</a> and the Bayers Road Cemetery.

<a href="/facts/Hugh_MacLennan/aIEF0Lbm">Hugh MacLennan</a>'s novel <a href="/facts/Barometer_Rising/xoDnAR8o">Barometer Rising</a> (1941) is set in Halifax at the time of the explosion and includes a carefully researched description of its impact on the city.<a class="footnote-ref" id="fnref:209" href="#fn:209">209</a><a class="footnote-ref" id="fnref:210" href="#fn:210">210</a> Following in MacLennan's footsteps, journalist <a href="/facts/Robert_MacNeil/7vng45Wt">Robert MacNeil</a> penned <a href="/facts/Burden_of_Desire/LeactVX5">Burden of Desire</a> (1992) and used the explosion as a metaphor for the societal and cultural changes of the day.<a class="footnote-ref" id="fnref:211" href="#fn:211">211</a> MacLennan and MacNeil's use of the romance genre to fictionalize the explosion is similar to the first attempt by <a href="/facts/Lieutenant-Colonel_Frank_McKelvey_Bell/QheRxn5E">Lieutenant-Colonel Frank McKelvey Bell</a>, author of the novella <a href="/facts/A_Romance_of_the_Halifax_Disaster/QheRxn5E">A Romance of the Halifax Disaster</a> (1918).

The response to the explosion from Boston and the appreciation in Halifax cemented ongoing warm <a href="/facts/Boston%E2%80%93Halifax_relations/kL1r38pc">Boston–Halifax relations</a>. In 1918, Halifax sent <a href="/facts/Boston_Christmas_Tree/5WaERYlq">a Christmas tree to Boston</a> in thanks and remembrance for the help that the Boston <a href="/facts/Red_Cross/KcT9EGnA">Red Cross</a> and the Massachusetts Public Safety Committee provided immediately after the disaster.<a class="footnote-ref" id="fnref:215" href="#fn:215">215</a> That gift was revived in 1971 by the <a href="/facts/Lunenburg_County,_Nova_Scotia/7frXQgJl">Lunenburg County</a> Christmas Tree Producers Association, which began an annual donation of a large tree to promote Christmas tree exports as well as acknowledge Boston's support after the explosion. The gift was later taken over by the Nova Scotia government to continue the goodwill gesture and to promote trade and tourism.<a class="footnote-ref" id="fnref:216" href="#fn:216">216</a> The tree is Boston's official Christmas tree and is lit on <a href="/facts/Boston_Common/azSjry1e">Boston Common</a> throughout the holiday season. In deference to its symbolic importance for both cities, the Nova Scotia Department of Natural Resources has specific guidelines for selecting the tree<a class="footnote-ref" id="fnref:217" href="#fn:217">217</a> and has tasked an employee to oversee the selection.<a class="footnote-ref" id="fnref:218" href="#fn:218">218</a>
