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 throng 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.
