D-Day for Revolutionary War reenactors is April 19 -- the Massachusetts state holiday known as Patriots Day. Early that morning, minute men and redcoats will clash on the Lexington town green, re-creating the famous events of April 19, 1775.
See a few of the locations visited by the midnight riders, Paul Revere and William Dawes, and the site of the "shot heard 'round the world" on the historic day that began the American Revolution.
Both doctors, Joseph Warren and Benjamin Church were closely connected to the events of April 18-19, 1775, and thus to the American Revolution as a whole.
