The Northern theatre of the American Revolutionary War also known as the Northern Department of the Continental Army was a theatre of operations during the American Revolutionary War. It was originally called the New York Department, and consisted of all of New York State. On November 12, 1776, after the British occupation of New York City, the Highlands Department was created out of the Northern Department. The Northern Department then stopped 30 miles south of Albany. After that, it was always referred to as the Northern Department.
