in parade-ground formation, on Lexington Common. They were in plain sight (not hiding behind walls), but not blocking the road to Concord. They made a show of political and military determination, but no effort to prevent the march of the Regulars. Many years later, one of the participants recalled Parker's words as being what is now engraved in stone at the site of the battle: "Stand your ground; don't fire unless fired upon, but if they mean to have a war, let it begin here." According to Parker's sworn deposition taken after the battle: Rather than turn left towards Concord, Marine Lieutenant Jesse Adair, at the head of the advance guard, decided on his own to protect the flank of the British column by first turning right and then leading the companies onto the Common itself, in a confused effort to surround and disarm the militia. Major Pitcairn arrived from the rear of the advance force and led his three companies to the left and halted them. The remaining companies under Colonel Smith lay further down the road toward Boston. First shot A British officer (probably Pitcairn, but accounts are uncertain, as it may also have been Lieutenant William Sutherland) then rode forward, waving his sword, and called out for the assembled militia to disperse, and may also have ordered them to "lay down your arms, you damned rebels!" Captain Parker told his men instead to disperse and go home, but, because of the confusion, the yelling all around, and due to the raspiness of Parker's tubercular voice, some did not hear him, some left very slowly, and none laid down their arms. Both Parker and Pitcairn ordered their men to hold fire, but a shot was fired from an unknown source. According to one member of Parker's militia, none of the Americans had discharged their muskets as they faced the oncoming British troops. The British did suffer one casualty, a slight wound, the particulars of which were corroborated by a deposition made by Corporal John Munroe. Munroe stated that: 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
