Maryland played a pivotal role in the American Revolution: Maryland was the site of several important battles during the American Revolution, including the Battle of Camden, the Battle of Cowpens, and the Battle of Yorktown. Additionally, Maryland's own soldiers played a crucial role in the war effort, including the famous "Maryland 400" who held off a British attack at the Battle of Long Island in 1776.
