Joseph Warren

Joseph Warren was an American physician who played a leading role in Patriot organizations in Boston during the early days of the American Revolution, eventually serving as President of the revolutionary Massachusetts Provincial Congress. Warren enlisted Paul Revere and William Dawes on April 18, 1775, to leave Boston and spread the alarm that the British garrison in Boston was setting out to raid the town of Concord and arrest rebel leaders John Hancock and Samuel Adams. Warren participated in the Battles of Lexington and Concord the following day, which are commonly considered to be the opening engagements of the American Revolutionary War.
