The unnamed friend climbs up the steeple and soon sets up two signal lanterns, informing Revere that the British are coming by sea.

Though he admitted the book made little impact,[5] it was written for his best friend, Charles Sumner, an activist abolitionist politician with whom he would continue to share common cause on the issues of slavery and the Union.
