1. One lantern hung in the bell-tower of Christ Church in Boston indicated troops would be marching "by land" out Boston Neck.
2. Two lanterns indicated troops would row "by sea" across the Charles River to Cambridge.
On the way to Lexington, Revere "alarmed" the country-side, stopping at each house, and arrived in Lexington around midnight. As he approached the house where Adams and Hancock were staying, a sentry asked that he not make so much noise.
"Noise!" cried Revere, "You'll have noise enough before long. The regulars are coming out!"
After delivering his message, Revere was joined by a second rider, William Dawes, who had been sent on the same errand by a different route. Deciding on their own to continue on to Concord, Massachusetts, where weapons and supplies were hidden, Revere and Dawes were joined by a third rider, Dr. Samuel Prescott.
Soon after, all three were arrested by a British patrol. Prescott escaped almost immediately, and Dawes soon after. Revere was held for some time and then released. Left without a horse, Revere returned to Lexington in time to witness part of the battle on the Lexington Green.
