B. 1751 When Paul Revere and William Dawes left Lexington on their way to Concord, they were joined by Samuel Prescott - a young doctor from Concord. Prescott was a member of the Sons of Liberty, a natural choice for an anti-British night-time ride. Prescott was in Lexington that night to visit his fiancée - I assume that's who we saw run off. He was intending to return home late - a happy coincidence for Revere and Dawes. Prescott knew the area well, so when the three men were stopped by British troops, it was Prescott who managed to elude his pursuers and reach Concord to sound the alarm.
