During the battles of Lexington and Concord on April 19, 1775, the British forces suffered significant casualties, totaling 73 dead and 174 wounded.

The losses sustained by the military force were significant, particularly given the well-trained and well-equipped nature of the British troops. These skirmishes underscored the determined resistance of the American militia, who employed guerrilla tactics to challenge the British forces. The substantial casualty figures not only indicated the ferocity of the conflict but also helped to rally colonial support for independence, representing a pivotal moment in the American Revolutionary War.
