On February 22, 1775, General Thomas Gage issued orders to Brown and De Berniere to travel outside of Boston and make a map of the roads and landmarks. It is believed that this is the map they made, which was subsequently used to plan and carry out the British expedition that led to the Battle of Lexington and the Battle of Concord. Of note, the village of Lexington is not on the map, but is below Lincoln, in the area where it says, “Eight Miles to Lincoln” on the map.
