Awakened by musket fire, men assembled at the First Parish Meeting house at 7:00 a.m. They marched down Estabrook trail to juncture of what is now the Isaac Davis trail where they joined with men from the Acton-Sudbury area. Then they moved to the muster site at Buttrick Farm hillside on the west bank of the Concord River near Old North Bridge at 9 a.m. Carlisle men fought and remained with the Acton men as the British retreated back to Arlington, Cambridge, Somerville, and Charlestown. None of the men were killed or wounded and most served one day only.            

Joe Monroe's home was on this site. The story is told that as the troops formed to cross the North Bridge, and the shots of the British killed some, the regular musicians faltered in playing the martial music to lead the volunteers. When the Commander called for assistance, Corporal Joe Monroe quickly stepped forward. He said, "I am so old that I will not matter if I'm killed." He hastily struck up a tune and advanced toward the bridge, followed by the men who no longer hesitated. It is said that Mr. Monroe was the white-haired old man shown in a famous painting of the Concord Flight, and that he was over 89 years of age and lived to be one hundred years old.            

Built by Capt. John Heald, who lived here after the Revolutionary War. He was one of the group of soldiers who went to Fort Ticonderoga.

Cannons were buried in front of the tavern at the base of an old elm tree.

There is an old lane at this spot that leads to the former tavern site.
