Boston Massacre, 1770, pre-Revolutionary incident growing out of the resentment against the British troops sent to Boston to maintain order and to enforce the Townshend Acts. The troops, constantly tormented by irresponsible gangs, finally (Mar. 5, 1770) fired into a rioting crowd and killed five men—three on the spot, two of wounds later. The funeral of the victims was the occasion for a great patriot demonstration. The British captain, Thomas Preston, and his men were tried for murder, with Robert Treat Paine as prosecutor, John Adams and Josiah Quincy as lawyers for the defense. Preston and six of his men were acquitted; two others were found guilty of manslaughter, punished, and discharged from the army.
