<P> I...ordered our Militia to meet on the Common in said Lexington to consult what to do, and concluded not to be discovered, nor meddle or make with said Regular Troops (if they should approach) unless they should insult or molest us; and, upon their sudden Approach, I immediately ordered our Militia to disperse, and not to fire:--Immediately said Troops made their appearance and rushed furiously, fired upon, and killed eight of our Party without receiving any Provocation therefor from us . </P> <P> 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 . </P> <P> 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 . </P> <P> (A) t 5 o'clock we arrived (in Lexington), and saw a number of people, I believe between 200 and 300, formed in a common in the middle of town; we still continued advancing, keeping prepared against an attack though without intending to attack them; but on our coming near them they fired on us two shots, upon which our men without any orders, rushed upon them, fired and put them to flight; several of them were killed, we could not tell how many, because they were behind walls and into the woods . We had a man of the 10th light Infantry wounded, nobody else was hurt . We then formed on the Common, but with some difficulty, the men were so wild they could hear no orders; we waited a considerable time there, and at length proceeded our way to Concord . </P>
