Lafayette in the Somewhat United States by Sarah Vowell:
Lee had recently been returned to the Continentals at Valley Forge through a prisoner exchange. He was, technically, Washington’s second in command. The two had served together in the French and Indian War. An Englishman hailing from Cheshire, Lee spent nearly twenty years as an officer in His Majesty’s army before retiring and settling in Virginia in 1773. The more experienced Lee had expected the Continental Congress to appoint him commander in chief of the Continental Army back in ’75. He never really got over Washington getting the job instead. In 1776 Washington had one of the Continentals’ Hudson River forts renamed after him, which is how the city of Fort Lee, New Jersey, got its name.
