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.

The Philadelphia campaign (1777–1778) was a British military campaign during the American Revolutionary War designed to gain control of Philadelphia, the Revolutionary-era capital where the Second Continental Congress convened and formed the Continental Army and appointed George Washington as its commander in 1775, and authored and unanimously adopted the Declaration of Independence the following year, on July 4, 1776, which formalized and escalated the war.
