context: Some witnesses among the regulars reported the first shot was fired by a colonial onlooker from behind a hedge or around the corner of a tavern. Some observers reported a mounted British officer firing first. Both sides generally agreed that the initial shot did not come from the men on the ground immediately facing each other. Speculation arose later in Lexington that a man named Solomon Brown fired the first shot from inside the tavern or from behind a wall, but this has been discredited. Some witnesses (on each side) claimed that someone on the other side fired first; however, many more witnesses claimed to not know. Yet another theory is that the first shot was one fired by the British, that killed Asahel Porter, their prisoner who was running away (he had been told to walk away and he would be let go, though he panicked and began to run). Historian David Hackett Fischer has proposed that there may actually have been multiple near-simultaneous shots. Historian Mark Urban claims the British surged forward with bayonets ready in an undisciplined way, provoking a few scattered shots from the militia. In response the British troops, without orders, fired a devastating volley. This lack of discipline among the British troops had a key role in the escalation of violence.

context: The first shots were fired just as the sun was rising at Lexington. Eight militiamen were killed, including Ensign Robert Munroe, their third in command. The British suffered only one casualty. The militia were outnumbered and fell back, and the regulars proceeded on to Concord, where they broke apart into companies to search for the supplies. At the North Bridge in Concord, approximately 400 militiamen engaged 100 regulars from three companies of the King's troops at about 11:00am, resulting in casualties on both sides. The outnumbered regulars fell back from the bridge and rejoined the main body of British forces in Concord.
