At the beginning of the American Revolutionary War, on April 19, 1775, a company of minutemen from Acton responded to the call to arms initiated by Paul Revere (who rode with other riders, William Dawes and Samuel Prescott, with Prescott the only one of the three who was able reach Acton itself) and fought at the North Bridge in Concord as part of the Battle of Lexington and Concord. The Acton minutemen were led by Captain Isaac Davis. When a company was needed to lead the advance on the bridge which was defended by the British regulars, Captain Davis was heard to reply, "I haven't a man who is afraid to go."
