Major John Buttrick (20 July 1731—16 May 1791, Concord, Massachusetts) was one of the leaders of the Concord militia during the Battle of Concord on April 19, 1775. Given the usual interpretation of the first stanza of Ralph Waldo Emerson's famous poem "Concord Hymn," Buttrick is the man who fired (the shot heard around the world.)
Buttrick played two notably critical roles in the Battle of Concord. Prior to the battle, the Concord militia and neighboring towns—then outnumbered by about 700 to 250—retreated to a ridge overlooking Concord as its command discussed immediate strategy. Colonel James Barrett surrendered the town of Concord and led the men across its Old North Bridge to a hill about a mile north of town, where they could continue to watch the troop movements of the British and the activities in the center of town. (This step proved fortuitous, as the ranks of troops continued to grow as Minuteman companies and additional militia arriving from the western towns joined them there.)
British Companies from the 4th and 10th Regiments, led by relatively inexperienced commander Captain Walter Laurie, had been stationed to guard their return route of the British troops; one company from the 43rd Regiment remained guarding the bridge itself. Upon seeing smoke rising from the village square, and seeing only a few companies directly below them, Colonel Barrett decided to march back toward the town from their vantage point on Punkatasset Hill to a lower, closer flat hilltop about 300 yards (274 m) from the North Bridge. Five full companies of Minutemen and five more of militia from Acton, Concord, Bedford and Lincoln occupied this hill as more groups of men streamed in, totaling at least 400 against Captain Laurie's light infantry companies, a force totaling 90–95 men.
As the militia advanced, the by now outnumbered British troops retreated from their position near the road to the bridge, yielding the hill to Barrett's men. Barrett ordered the Massachusetts men to form one long line two abreast on the highway leading down to the bridge. At around 10:30 a.m., after further consultation with his fellow officers, Barrett told the men to load their weapons but not to fire unless fired upon, and then ordered them to advance to the bridge. The militia troops approached the bridge in a column of two men abreast, they were led by their officers: Captain Isaac Davis, Major Buttrick of Concord, and Lt. Col. John Robinson of Westford.
