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 regulars rode on the cannon and were forced to hop off when they were fired at by gatherings of militia.
 Percy's men were often surrounded, but they had the tactical advantage of interior lines.
 Percy could shift his units more easily to where they were needed, while the colonial militia were required to move around the outside of his formation.
Percy placed Smith's men in the middle of the column, while the 23rd Regiment's line companies made up the column's rear guard.
Because of information provided by Smith and Pitcairn about how the Americans were attacking, Percy ordered the rear guard to be rotated every mile or so, to allow some of his troops to rest briefly.
Flanking companies were sent to both sides of the road, and a powerful force of Marines acted as the vanguard to clear the road ahead.

During the respite at Lexington, Brigadier General William Heath arrived and took command of the militia.
 Earlier in the day, he had traveled first to Watertown to discuss tactics with Joseph Warren, who had left Boston that morning, and other members of the Massachusetts Committee of Safety.
 Heath and Warren reacted to Percy's artillery and flankers by ordering the militiamen to avoid close formations that would attract cannon fire.
 Instead, they surrounded Percy's marching square with a moving ring of skirmishers at a distance to inflict maximum casualties at minimum risk.

A few mounted militiamen on the road would dismount, fire muskets at the approaching regulars, then remount and gallop ahead to repeat the tactic.
 Unmounted militia would often fire from long range, in the hope of hitting somebody in the main column of soldiers on the road and surviving, since both British and colonials used muskets with an effective combat range of about 50 yards (46 m).
 Infantry units would apply pressure to the sides of the British column.
 When it moved out of range, those units would move around and forward to re-engage the column further down the road.
 Heath sent messengers out to intercept arriving militia units, directing them to appropriate places along the road to engage the regulars.
 Some towns sent supply wagons to assist in feeding and rearming the militia.
 Heath and Warren did lead skirmishers in small actions into battle themselves, but it was the presence of effective leadership that probably had the greatest impact on the success of these tactics.

The fighting grew more intense as Percy's forces crossed from Lexington into Menotomy.
 Fresh militia poured gunfire into the British ranks from a distance, and individual homeowners began to fight from their own property.
 Some homes were also used as sniper positions, turning the situation into a soldier's nightmare: house-to-house fighting.
Jason Russell pleaded for his friends to fight alongside him to defend his house by saying, "An Englishman's home is his castle."
 He stayed and was killed in his doorway.
 His friends, depending on which account is to be believed, either hid in the cellar, or died in the house from bullets and bayonets after shooting at the soldiers who followed them in.
 The Jason Russell House still stands and contains bullet holes from this fight.
 A militia unit that attempted an ambush from Russell's orchard was caught by flankers, and eleven men were killed, some allegedly after they had surrendered.

Percy lost control of his men, and British soldiers began to commit atrocities to repay for the supposed scalping at the North Bridge and for their own casualties at the hands of a distant, often unseen enemy.
Based on the word of Pitcairn and other wounded officers from Smith's command, Percy had learned that the Minutemen were using stone walls, trees and buildings in these more thickly settled towns closer to Boston to hi
