The British objective at the North Bridge in Concord was to destroy American military supplies, which they believed were stored there.

On April 19, 1775, British forces moved forward to capture resources they perceived as a challenge to their authority over the colonies. In response, colonial militias were notified and assembled to oppose them. Upon reaching the North Bridge, the British encountered fierce resistance from the militia, resulting in casualties for the British and marking a pivotal moment in the conflict that signaled the beginning of open rebellion.
