When I got to Dr. Warren's house, I found he had sent an express by land to Lexington -- a Mr. William Dawes.
The Sunday before, by desire of Dr. Warren, I had been to Lexington, to Messrs. Hancock and Adams, who were at the Rev. Mr. Clark's.
I returned at night through Charlestown; there I agreed with a Colonel Conant and some other gentlemen, that if the British went out by water, we would show two lanthorns in the North Church steeple and if by land, one as a signal; for we were apprehensive it would be difficult to cross the Charles River, or get over Boston Neck.
I left Dr. Warren, called upon a friend, and desired him to make the signals. I then went home, took my boots and surtout, went to the north part of the town, where I kept a boat; two friends rowed me across Charles River a little to the eastward where the Somerset man-of-war lay. It was then young flood, the ship
was winding, and the moon rising.
They landed me on the Charlestown side. When I got into town, I met Colonel Conant and several others; they said they had seen our signals. I told them what was acting, and went to get me a horse; I got a horse of Deacon Larkin."
