Halifax Explosion
On the morning of 6 December 1917, the French cargo ship collided with the Norwegian vessel in the waters of Halifax, Nova Scotia, Canada. The ''Mont-Blanc'', laden with high explosives, caught fire and exploded, devastating the Richmond district of Halifax. 1,782 people were killed, largely in Halifax and Dartmouth, by the blast, debris, fires, or collapsed buildings, and an estimated 9,000 others were injured. The blast was the largest human-made explosion at the time, releasing the equivalent energy of roughly . ''Mont-Blanc'' was under orders from the French government to carry her cargo from New York City via Halifax to Bordeaux, France. At roughly 8:45 am, she collided at low speed, approximately one knot (), with the unladen ''Imo'', chartered by the Commission for Relief in Belgium to pick up a cargo of relief supplies in New York. On the ''Mont-Blanc'', the impact damaged benzol barrels stored on deck, leaking vapours which were ignited by sparks from the ...

Pyrocumulus Cloud
A flammagenitus cloud, also known as a flammagenitus, pyrocumulus cloud, or fire cloud, is a dense Cumulus cloud, cumuliform cloud associated with fire or volcanic eruptions. A flammagenitus is similar dynamically in some ways to a firestorm, and the two phenomena may occur in conjunction with each other. However, either may occur without the other. Formation A flammagenitus cloud is produced by the intense heating of the air from the surface. The intense heat induces Atmospheric convection, convection, which causes the air mass to rise to a point of stability, usually in the presence of moisture. Phenomena such as volcanic eruptions and wildfire, forest fires can induce formation of this cloud, by mechanisms similar to those that form Anthropogenic cloud, homogenitus clouds. The presence of a low-level jet stream can enhance its formation. Condensation of ambient moisture (moisture already present in the atmosphere), as well as moisture evaporated from burnt vegetation or vo ...

Northeastern United States
The Northeastern United States, also referred to as the Northeast, the East Coast, or the American Northeast, is a geographic region of the United States. It is located on the Atlantic coast of North America, with Canada to its north, the Southern United States to its south, and the Midwestern United States to its west. The Northeast is one of the four regions defined by the U.S. Census Bureau for the collection and analysis of statistics.

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CFB Halifax
Canadian Forces Base (CFB) Halifax is Canada's east coast naval base and home port to the Royal Canadian Navy Atlantic fleet, known as Canadian Fleet Atlantic (CANFLTLANT), that forms part of the formation Maritime Forces Atlantic (MARLANT). It is the largest Canadian Forces Base in terms of the number of posted personnel and is formed from an amalgamation of military properties situated around the strategic Halifax Harbour in Nova Scotia. Majesty's Canadian Dockyard (HMC Dockyard Halifax) History HMC Dockyard Halifax was acquired by the Canadian government from the Royal Navy following the withdrawal of British military forces from Canada in 1906.

Royal Naval Dockyard, Halifax
Royal Naval Dockyard, Halifax was a Royal Navy base in Halifax, Nova Scotia. Established in 1759, the Halifax Yard served as the headquarters for the Royal Navy's North American Station for sixty years, starting with the Seven Years' War. The Royal Navy continued to operate the station until it was closed in 1905. The station was sold to Canada in 1907 becoming Her Majesty's Canadian Dockyard, a function it still serves today as part of CFB Halifax. History Halifax Harbour had served as a Royal Navy seasonal base from the founding of the city in 1749, using temporary facilities and a careening beach on Georges Island. The British purchased the property which now contains the Fleet Maintenance Facility Cape Scott for the Naval Yard. This property had belonged to John Gorham (Gorham Point), Captain Ephraim Cook, Philip Durell, Joseph Gerrish and William Nesbitt. (In the summer of 1751, Gorham built the first registered vessel in Halifax, a brig he named Osborn Galley at Go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intercolonial Railway
The Intercolonial Railway of Canada , also referred to as the Intercolonial Railway (ICR), was a historic Canadian railway that operated from 1872 to 1918, when it became part of Canadian National Railways. As the railway was also completely owned and controlled by the Government of Canada, the Intercolonial was also one of Canada's first Crown corporations. Origins The idea of a railway connecting Britain's North American colonies arose as soon as the railway age began in the 1830s. In the decades following the War of 1812 and ever-mindful of the issue of security, the colonies of Upper and Lower Canada (later the Province of Canada after 1840) wished to improve land-based transportation with the Atlantic coast colonies of Nova Scotia and New Brunswick, and to a lesser extent Prince Edward Island and Newfoundland. A railway connection from the Province of Canada to the British colonies on the coast would serve a vital military purpose during the winter months when the waters o ...

War Of 1812
The War of 1812 (18 June 1812 – 17 February 1815) was fought by the United States of America and its indigenous allies against the United Kingdom and its allies in British North America, with limited participation by Spain in Florida. It began when the United States declared war on 18 June 1812 and, although peace terms were agreed upon in the December 1814 Treaty of Ghent, did not officially end until the peace treaty was ratified by Congress on 17 February 1815. Tensions originated in long-standing differences over territorial expansion in North America and British support for Native American tribes who opposed US colonial settlement in the Northwest Territory. These escalated in 1807 after the Royal Navy began enforcing tighter restrictions on American trade with France and press-ganged men they claimed as British subjects, even those with American citizenship certificates. Opinion in the US was split on how to respond, and although majorities in both the House and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Napoleonic Wars
The Napoleonic Wars (1803–1815) were a series of major global conflicts pitting the French Empire and its allies, led by Napoleon I, against a fluctuating array of European states formed into various coalitions. It produced a period of French domination over most of continental Europe. The wars stemmed from the unresolved disputes associated with the French Revolution and the French Revolutionary Wars consisting of the War of the First Coalition (1792–1797) and the War of the Second Coalition (1798–1802). The Napoleonic Wars are often described as five conflicts, each termed after the coalition that fought Napoleon: the Third Coalition (1803–1806), the Fourth (1806–1807), the Fifth (1809), the Sixth (1813–1814), and the Seventh (1815) plus the Peninsular War (1807–1814) and the French invasion of Russia (1812). Napoleon, upon ascending to First Consul of France in 1799, had inherited a republic in chaos; he subsequently created a state with stable financ ...

American Revolution
The American Revolution was an ideological and political revolution that occurred in British America between 1765 and 1791. The Americans in the Thirteen Colonies formed independent states that defeated the British in the American Revolutionary War (1775–1783), gaining independence from the British Crown and establishing the United States of America as the first nation-state founded on Enlightenment principles of liberal democracy. American colonists objected to being taxed by the Parliament of Great Britain, a body in which they had no direct representation. Before the 1760s, Britain's American colonies had enjoyed a high level of autonomy in their internal affairs, which were locally governed by colonial legislatures. During the 1760s, however, the British Parliament passed a number of acts that were intended to bring the American colonies under more direct rule from the British metropole and increasingly intertwine the economies of the colonies with those of Brit ...

Privateers
A privateer is a private person or ship that engages in maritime warfare under a commission of war. Since robbery under arms was a common aspect of seaborne trade, until the early 19th century all merchant ships carried arms. A sovereign or delegated authority issued commissions, also referred to as a letter of marque, during wartime. The commission empowered the holder to carry on all forms of hostility permissible at sea by the usages of war. This included attacking foreign vessels and taking them as prizes, and taking prize crews as prisoners for exchange. Captured ships were subject to condemnation and sale under prize (law), prize law, with the proceeds divided by percentage between the privateer's sponsors, shipowners, captains and crew. A percentage share usually went to the issuer of the commission (i.e. the sovereign). Privateering allowed sovereigns to raise revenue for war by mobilizing privately owned armed ships and sailors to supplement state power. For participants, ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
