The Royal Fusiliers (City of London Regiment) was a line infantry regiment of the British Army in continuous existence for 283 years. It was known as the 7th Regiment of Foot until the Childers Reforms of 1881. It was formed as a fusilier regiment in 1685 by George Legge, 1st Baron Dartmouth, from two companies of the Tower of London guard, and was originally called the Ordnance Regiment, later the Royal Regiment of Fusiliers. The Royal Fusiliers were sent to Canada in April 1773. The regiment was broken up into detachments that served at Montreal, Quebec, Fort Chambly and Fort St Johns. In the face of the American invasion of Canada in 1775/76, the 80 man garrison of Fort Chambly attempted to resist a 400-man Rebel force but ultimately had to surrender, losing its regimental colors as a result. The bulk of the regiment was captured when St John's fell. The men taken prisoner during the defense of Canada were exchanged in British held New York City in December 1776.
