<P> The regulars found themselves trapped in a situation where they were both outnumbered and outmaneuvered . Lacking effective leadership and terrified at the superior numbers of the enemy, with their spirit broken, and likely not having experienced combat before, they abandoned their wounded, and fled to the safety of the approaching grenadier companies coming from the town center, isolating Captain Parsons and the companies searching for arms at Barrett's Farm . </P> <P> The colonists were stunned by their success . No one had actually believed either side would shoot to kill the other . Some advanced; many more retreated; and some went home to see to the safety of their homes and families . Colonel Barrett eventually began to recover control . He moved some of the militia back to the hilltop 300 yards (274 m) away and sent Major Buttrick with others across the bridge to a defensive position on a hill behind a stone wall . </P> <P> Lieutenant Colonel Smith heard the exchange of fire from his position in the town moments after he received the request for reinforcements from Laurie . He quickly assembled two companies of grenadiers to lead toward the North Bridge himself . As these troops marched, they met the shattered remnants of the three light infantry companies running towards them . Smith was concerned about the four companies that had been at Barrett's, since their route to town was now unprotected . When he saw the Minutemen in the distance behind their wall, he halted his two companies and moved forward with only his officers to take a closer look . One of the Minutemen behind that wall observed, "If we had fired, I believe we could have killed almost every officer there was in the front, but we had no orders to fire and there wasn't a gun fired ." During a tense standoff lasting about 10 minutes, a mentally ill local man named Elias Brown wandered through both sides selling hard cider . </P> <P> At this point, the detachment of regulars sent to Barrett's farm marched back from their fruitless search of that area . They passed through the now mostly - deserted battlefield, and saw dead and wounded comrades lying on the bridge . There was one who looked to them as if he had been scalped, which angered and shocked the British soldiers . They crossed the bridge and returned to the town by 11: 30 a.m., under the watchful eyes of the colonists, who continued to maintain defensive positions . The regulars continued to search for and destroy colonial military supplies in the town, ate lunch, reassembled for marching, and left Concord after noon . This delay in departure gave colonial militiamen from outlying towns additional time to reach the road back to Boston . </P>
