Dr. Warren had arranged with these two men for this especial work, and so they were ready. Dawes had left home that afternoon, not even confiding to his wife his intention. Immediately after the embarkation he was ready and on his way. He managed to elude the guard at Boston Neck by passing out with some soldiers. His ride was then through Roxbury, Brookline, Brighton, over the Charles River there by bridge into Cambridge, at Harvard Square, and thence directly on to Lexington. So much longer was his route than Revere's, that he did not reach there until half an hour later than Revere did, and then found that Hancock and Adams had been alarmed. The work of William Dawes was efficient over the route he traveled. In Lexington, Revere waited for Dawes, and from there onwards toward Concord they traveled together. It is to be regretted that a more detailed account of the ride of William Dawes cannot be given. But momentary flashes of light reveal his course and his work. Revere left a narrative of his ride, and historians have fallen into the error of supposing him to be the only messenger with the warlike tidings. As we progress with this narrative we shall surmise that William Dawes and Paul Revere were but two out of many, for the exciting news radiated in every direction, and could only have been borne by riders equally as patriotic and fleet as those two.

The previous Sunday evening Paul Revere had been out to Lexington, for a conference with Hancock and Adams, and on his return that same night to Charlestown he had agreed with Col. Conant and some others to display lanterns in the North Church steeple, if the troops should march; one lantern if they went by land, which meant out over Boston Neck, through Roxbury, Brookline, and Brighton, into Harvard Square, Cambridge; and two, if they crossed the Charles River in boats and landed at Lechmere Point in East Cambridge. This arrangement was made because it was surmised that no messenger would be allowed to leave Boston with the news while the troops were leaving.

When Revere left Warren his first duty was to call upon Capt. John Pulling, Jr.,[45] and arrange for the signal lanterns. Then he went to his home in North Square for his boots and surtout, and from there to where his boat was moored beneath a cob-wharf, near the present Craigie Bridge, in the north part of the town. Two friends accompanied him, Joshua Bentley and Thomas Richardson.[46]

Their point of starting was not far from the then Charlestown Ferry, the boats of which were drawn up nightly at nine o'clock. Out in the Charles River was anchored the Somerset, a British man-of-war. It was young flood, and the moon was rising.[47] Fearing that the noise of the oars in the oar-locks might alarm the sentry, Revere despatched one of his companions for something to muffle them with, who soon returned with a petticoat, yet warm from the body of a fair daughter of Liberty who was glad to contribute to the cause.[48] Rowing out into the river and passing to the eastward of the Somerset they looked back and there shining from the tall steeple of Christ Church, the Old North, were two signal lanterns.

Far up into the valleys of the Mystic and the Charles, those twinkling rays gleamed, and their meaning picked up wherever it fell, was carried still farther to the remoter hamlets and villages beyond the hills.

When Capt. Pulling left Paul Revere he proceeded at once to the home of the sexton of Christ Church, Robert Newman, who lived on Salem St., opposite Bennett St. Pulling was vestryman of the church and when he demanded the keys of Newman they were handed to him without question. Pulling proceeded to the church, climbed the belfry stairs, hung two lighted lanterns out of the highest little window, forty-two feet above the sidewalk,[49] descended and made his exit through a window, and so escaped unnoticed.

These lanterns were seen by all who looked, and quickly British soldiers sought out the sexton and placed him under arrest. His denial of any knowledge as to who displayed the lanterns was believed, and he was released. Pulling, disguised as a sailor, escaped from Boston in a fishing vessel, landed in Nantucket, and did not return until after the siege.[50]

Revere and his two companions reached the Charlestown shore in safety. Their landing place was near the old battery at Gage's Wharf, not far from No. 85 of the present Water St., near City Square. They were met by Col. Conant and several others, who reported that the lanterns had been seen and interpreted. While Revere was waiting for his horse, which was furnished by Deacon Larkin, Richard Devens, one of the Committee of Safety, came and told Revere that as he came down the road from Lexington after sundown that evening, he met ten British officers, all well mounted and armed, going up the road.
