French and Indian War: Robert Rogers and his Rangers surprise French held Fort Sainte Thérèse on the Richelieu River near Lake Champlain. The fort is raided and burned.

Lieutenant-Colonel Robert Rogers was a British Army officer and frontiersman. Born in Methuen, Province of Massachusetts Bay, he fought in King George's War, the French and Indian War and the American Revolutionary War. During the French and Indian War, Rogers raised and commanded Rogers' Rangers, a ranger unit trained for carrying out asymmetric warfare.

Rogers' Rangers was a company of soldiers from the Province of New Hampshire raised by Major Robert Rogers and attached to the British Army during the French and Indian War. The unit was quickly adopted into the New England Colonies army as an independent ranger company. Rogers was inspired by colonial Frontiersman Ranger groups across North America and the teachings of unconventional warfare from Rangers such as Benjamin Church. Rogers trained and commanded his own rapidly deployable light infantry force, which was tasked mainly with reconnaissance and conducting special operations against distant targets. Their tactics were built on earlier Colonial precedents and were codified for the first time by Rogers as his 28 "Rules of Ranging". The tactics proved remarkably effective, and the initial company was expanded into a ranging corps of more than a dozen companies containing as many as 1,200–1,400 men at its peak. The ranger corps became the chief scouting arm of British Crown forces by the late 1750s. The British forces in America valued Rogers' Rangers for their ability to gather intelligence about the enemy. They were disbanded in 1761.

Fort Sainte Thérèse is the name given to three different forts built successively on one site, among a series of fortifications constructed during the 17th century by France along the Richelieu River, in the province of Quebec, in Montérégie.

The Richelieu River is a river of Quebec, Canada, and a major right-bank tributary of the St. Lawrence River. It rises at Lake Champlain, from which it flows northward through Quebec and empties into the St. Lawrence. It was formerly known by the French as the Iroquois River and the Chambly River, and was named for Cardinal Richelieu, the powerful minister under Louis XIII.
