Moses Hazen was a brigadier general in the Continental Army during the American Revolutionary War. Born in the Province of Massachusetts Bay, he saw action in the French and Indian War with Rogers' Rangers. His service included particularly brutal raids, during the Expulsion of the Acadians and the 1759 Battle of Quebec. He was formally commissioned into the British Army, shortly before the war ended, and retired on half-pay outside Montreal, Province of Quebec, where he and Gabriel Christie, another British officer, made extensive land purchases in partnership. During his lifetime he acquired land in Quebec, New Hampshire, Vermont, and New York, but lost most of his Quebec land due to litigation, with Christie and the negative effects of the Revolution.

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 Seven Years' War. The unit was quickly adopted into the British army as an independent ranger company. Robert Rogers trained and commanded the rapidly deployed light infantry force, which was tasked mainly with reconnaissance as well as 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, so much so that the initial company was expanded into a ranging corps of more than a dozen companies. 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.
