song would become a popular anthem for the colonial forces. Percy took the land route across Boston Neck and over the Great Bridge, which some quick-thinking colonists had stripped of its planking to delay the British. His men then came upon an absent-minded tutor at Harvard College and asked him which road would take them to Lexington. The Harvard man, apparently oblivious to the reality of what was happening around him, showed him the proper road without thinking. (He was later compelled to leave the country for inadvertently supporting the enemy.) Percy's troops arrived in Lexington at about 2:00 p.m. They could hear gunfire in the distance as they set up their cannon and deployed lines of regulars on high ground with commanding views of the town. Colonel Smith's men approached like a fleeing mob with the full complement of colonial militia in close formation pursuing them. Percy ordered his artillery to open fire at extreme range, dispersing the colonial militiamen. Smith's men collapsed with exhaustion once they reached the safety of Percy's lines. Against the advice of his Master of Ordnance, Percy had left Boston without spare ammunition for his men or for the two artillery pieces they brought with them, thinking the extra wagons would slow him down. Each man in Percy's brigade had only 36 rounds, and each artillery piece was supplied with only a few rounds carried in side-boxes. After Percy had left the city, Gage directed two ammunition wagons guarded by one officer and thirteen men to follow. This convoy was intercepted by a small party of older, veteran militiamen still on the "alarm list", who could not join their militia companies because they were well over 60 years of age. These men rose up in ambush and demanded the surrender of the wagons, but the regulars ignored them and drove their horses on. The old men opened fire, shot the lead horses, killed two sergeants, and wounded the officer. The British survivors ran, and six of them threw their weapons into a pond before they surrendered. Lexington to Menotomy Percy assumed control of the combined forces of about 1,700 men and let them rest, eat, drink, and have their wounds tended at field headquarters (Munroe Tavern) before resuming the march. They set out from Lexington at about 3:30 p.m., in a formation that emphasized defense along the sides and rear of the column. Wounded
