Paul Revere and William Dawes were detained by a British Army patrol nearby during the "Midnight Ride" to Concord of April 18. Samuel Prescott, who was also riding with them, escaped by jumping his horse over a wall and into the woods. Prescott emerged at the Hartwell Tavern, awakened Ephraim and informed him of the pending arrival of the British soldiers. Ephraim sent his black slave, Violet, down the road to alert his son and his family. Mary then relayed the message to Captain William Smith. The minutemen received the notice in time, and arrived at Old North Bridge before their enemy. Prescott made it to Concord.
