The American invasion of Canada in 1775–1776 captured Montreal but failed to take Quebec City, leading to a disastrous retreat. Short enlistments, lack of hard money, smallpox, Canadian resistance, and logistical failures combined to doom the campaign.
A research guide to locating and using contemporary and later maps of the War of 1812, covering published and manuscript maps, archival collections, and research methods.
The United States entered the War of 1812 with a small, poorly funded, and ill-trained regular army, further hampered by defective militia mobilization, aging and inexperienced commanders, and a lack of logistical planning. Chronic neglect during the Jefferson administration, reliance on the militia, and political divisions left the army unprepared for a conflict with Great Britain.
At the Battle of Beaver Dams on June 24, 1813, Kanyen’kehà:ka (Mohawk) warriors from Kahnawake and the Grand River, under British Indian Department officers, ambushed an American column near Thorold, Ontario, forcing its surrender. This victory, achieved largely through Indigenous guerrilla tactics, secured the Niagara frontier for Britain and ignited a lasting debate over who deserved credit for the battle.
During 1812, the United States relied heavily on state militias to fill the ranks of its small regular army. The militia’s constitutional limitations, poor training, and command disputes significantly shaped the early campaigns of the War of 1812, especially along the U.S.-Canadian border.
British–Indigenous alliances during the War of 1812 were strategic military and diplomatic partnerships between the British Empire and various First Nations and Native American groups. These alliances were crucial to the defence of British North America, but their collapse after Tecumseh’s death led to the abandonment of Indigenous territorial claims and facilitated American expansion.
Queenston Heights Battlefield is a National Historic Site in Niagara-on-the-Lake, Ontario, marking the site of the October 13, 1812 Battle of Queenston Heights. The battle, a British victory, was a turning point in the War of 1812 and is notable as the place where Major-General Sir Isaac Brock was killed.
USS Niagara, a 20-gun snow-brig, served as Oliver Hazard Perry’s relief flagship during the Battle of Lake Erie on 10 September 1813. After Perry transferred from the disabled Lawrence, Niagara broke the British line and secured a decisive American victory, ensuring control of Lake Erie.
The United States declared war on Britain on June 18, 1812, after years of maritime impressment, trade restrictions, and perceived British support for Indigenous resistance on the frontier. The decision followed President James Madison’s war message and reflected the competing pressures of honor, expansion, and political division.
British strategy on the Gulf Coast during the War of 1812 aimed at seizing New Orleans and controlling the Mississippi River. The campaign culminated in the Battle of New Orleans on 8 January 1815, a tactical American victory fought after the Treaty of Ghent had been signed.
