Before the arrival of Pitcairn the British officers who had captured Revere and Dawes returned with them to Lexington, where, commanding Revere to dismount, they let him go. Running off at full speed to the house where Samuel Adams and John Hancock were staying, he recounted what had happened, and then guided them across the fields to a place of safety at Woburn. On their way they heard the guns firing on Lexington Common, and the sound stirred the soul of Adams, who exclaimed with enthusiasm, "Oh, what a glorious morning is this!"

From Lexington, Colonel Smith hastened to Concord, arriving there at seven o'clock in the morning, about six hours after Dr. Prescott had given the alarm. The British could not find the military stores, most of which the people of Concord had hidden, but they cut down the liberty pole, set fire to the court-house, spiked a few cannon, and emptied some barrels of flour.

About 200 of them stood guard at the North Bridge, while a body of minute-men gathered on a hill beyond. When the minute-men had increased to 400 they advanced upon the British, and brought on a fight which resulted in loss of life on each side. Then continuing their advance they crossed the bridge, and forced the British to withdraw into the town.

By noon Colonel Smith could see that by reason of the ever-increasing body of minute-men, swarming into Concord from every direction, it would be unwise to delay his return to Boston. His men had marched eighteen miles with little or no food for fourteen hours, and were tired and hungry.

But when the British started back on their return march, the minute-men followed and began a deadly attack. It was an irregular fight. The minute-men, trained to woodland warfare, slipped from tree to tree, shot down the tired British soldiers, and then retreated only to return and repeat the annoying attack. The wooded country through which they marched favored this kind of fighting.

But even in the open country every stone wall and hill, every house and barn, seemed to the exhausted British troops to bristle with the guns of minute-men. The retreating army pushed wearily forward, fighting as bravely as possible, but on the verge of confusion and panic.

When they reached Lexington Common, at two o'clock, they met 1,200 fresh troops under Lord Percy, whose timely arrival saved the entire force from capture. The dismayed British troops, half-dead with exhaustion, entered the square Lord Percy had formed for their protection, and fell upon the ground, "with their tongues hanging out of their mouths like those of dogs after a chase."
