2 o'clock in the morning. Westford Minuteman, Rev. Joseph Thaxter, wrote of his account: In their accounts afterward, British officers and soldiers alike noted their frustration that the colonial militiamen fired at them from behind trees and stone walls, rather than confronting them in large, linear formations in the style of European warfare. This image of the individual colonial farmer, musket in hand and fighting under his own command, has also been fostered in American myth: "Chasing the red-coats down the lane / Then crossing the fields to emerge again / Under the trees at the turn of the road, / And only pausing to fire and load." To the contrary, beginning at the North Bridge and throughout the British retreat, the colonial militias repeatedly operated as coordinated companies, even when dispersed to take advantage of cover. Reflecting on the British experience that day, Earl Percy understood the significance of the American tactics: Percy's rescue General Gage had anticipated that Lt. Col. Smith's expedition might require reinforcement, so Gage drafted orders for reinforcing units to assemble in Boston at 4 a.m. But in his obsession for secrecy, Gage had sent only one copy of the orders to the adjutant of the 1st Brigade, whose servant then left the envelope on a table. Also at about 4 a.m., the British column was within three miles of Lexington, and Lt. Col. Smith now had a clear indication that all element of surprise had been lost and that alarm was spreading throughout the countryside. So he sent a rider back to Boston with a request for reinforcements. At about 5 a.m., the rider reached Boston, and the 1st Brigade was ordered to assemble: the line infantry companies of the 4th, 23rd, and 47th Regiments, and a battalion of Royal Marines, under the command of Earl Percy. Unfortunately for the British, once again only one copy of the orders was sent to each commander, and the order for the Royal Marines was delivered to the desk of Major John Pitcairn, who was already on the Lexington Common with Smith's column at that hour. After these delays, Percy's brigade, about 1,000 strong, left Boston at about 8:45 a.m., headed toward Lexington. Along the way, the story is told, they marched to the tune of "Yankee Doodle" to taunt the inhabitants of the area. By the Battle of Bunker Hill less than two months later, the
