Question: When did the war that the 84th Regiment was first involved in finally end? Passage:The 84th Regiment of Foot (Royal Highland Emigrants) was a British regiment in the American Revolutionary War that was raised to defend present day Ontario, Quebec and Atlantic Canada from the constant land and sea attacks by American Revolutionaries. The 84th Regiment was also involved in offensive action in the Thirteen Colonies; including North Carolina, South Carolina, Georgia, Virginia and what is now Maine, as well as raids upon Lake Champlain and the Mohawk Valley. The regiment consisted of 2,000 men in twenty companies. The 84th Regiment was raised from Scottish soldiers who had served in the Seven Years' War and stayed in North America. As a result, the 84th Regiment had one of the oldest and most experienced officer corps of any regiment in North America. The Scottish Highland regiments were a key element of the British Army in the American Revolution. The 84th Regiment was clothed, armed and accoutred the same as the Black Watch, with Lieutenant Colonel Allan Maclean commanding the first battalion and Major General John Small of Strathardle commanding the second. The two Battalions operated independently of each other and saw little action together.
