Revere stopped only to engage a friend to raise the concerted signals, and two friends rowed him across the Charles River five minutes before the sentinels received the order to prevent it. All was still, as suited the hour. The _Somerset_, man-of-war, was winding with the young flood; the waning moon just peered above a clear horizon, while from a couple of lanterns in the tower of the North Church the beacon streamed to the neighboring towns as fast as light could travel. A little beyond Charlestown Neck Revere was intercepted by two British officers on horseback, but being well mounted he turned suddenly and escaped by the road to Medford. In that town he waked the captain and Minute Men, and continued to rouse almost every house on the way to Lexington, making the memorable ride of Paul Revere. The troops had not advanced far when the firing of guns and ringing of bells announced that their expedition had been heralded, and Smith sent back for a reinforcement. Early on the nineteenth of April the message from Warren reached Adams and Hancock, who at once divined the object of the expedition. Revere, therefore, and Dawes, joined by Samuel Prescott, "a high Son of Liberty" from Concord, rode forward, calling up the inhabitants as they passed along, till in Lincoln they fell upon a party of British officers. Revere and Dawes were seized and taken back to Lexington, where they were released, but Prescott leaped over a low stone wall and galloped on for Concord. There, at about two hours after midnight, a peal from the bell of the meeting house brought together the inhabitants of the place, young and old, with their firelocks, ready to make good the resolute words of their town debates. Among the most alert was William Emerson, the minister, with gun in hand, his powder horn and pouch of balls slung over his shoulder. By his sermons and his prayers his flock learned to hold the defense of their liberties a part of their covenant with God. His presence with arms strengthened their sense of duty. From daybreak to sunrise, the summons ran from house to house through Acton. Express messengers and the call of Minute Men spread widely the alarm. How children trembled as they were scared out of sleep by the cries! How women, with heaving breasts, bravely seconded their husbands! How the countrymen, forced suddenly to arm, without guides or counsellors, took instant counsel of their courage! The mighty chorus of voices rose from the scattered farmhouses, and, as it were, from the ashes of the dead. "Come forth, champions of liberty; now free your country; protect your sons and daughters, your wives and homesteads; rescue the houses of the God of your fathers, the franchises handed down from your ancestors." Now all is at stake; the battle is for all.
