War of 1812: A combined force of British regulars, Canadian militia and Mohawks defeat the United States Army in the Battle of the Chateauguay.

The War of 1812 was fought by the United States and its allies against the United Kingdom and its allies in North America. It began when the United States declared war on Britain on 18 June 1812. Although peace terms were agreed upon in the December 1814 Treaty of Ghent, the war did not officially end until the peace treaty was ratified by the United States Congress on 17 February 1815.

British Regulars is a term commonly used to describe the Napoleonic-era British foot soldiers who were known for their distinct red uniform and well-disciplined combat performance. These soldiers were members of the regular army, as compared to irregular military such as private armies or mercenaries.

The Canadian Militia is a historical title for military units raised for the defence of Canada. The term has been used to describe sedentary militia units raised from local communities in Canada; as well as the regular army for the Province of Canada and post-confederated Canada, referred to as the active militias.

The Mohawk, also known by their own name, Kanien'kehá:ka, are an Indigenous people of North America and the easternmost nation of the Haudenosaunee, or Iroquois Confederacy.

The United States Army (USA) is the primary land service branch of the United States Department of Defense. It is designated as the Army of the United States in the United States Constitution. It operates under the authority, direction, and control of the United States secretary of defense. It is one of the six armed forces and one of the eight uniformed services of the United States. The Army is the most senior branch in order of precedence amongst the armed services. It has its roots in the Continental Army, formed on 14 June 1775 to fight against the British for independence during the American Revolutionary War (1775–1783). After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.
