The outcomes at Lexington and Concord had a profound impact on future military strategies, encouraging the use of unconventional warfare among the colonial forces.

The early clashes demonstrated that conventional British tactics, which relied on linear formations and open-field battles, could be successfully challenged by guerrilla warfare. Colonial militias started using ambushes, hit-and-run tactics, and their familiarity with the local landscape to outsmart British forces. This change enabled smaller, less formally trained groups to interfere with British operations and achieve considerable psychological benefits. As the Revolutionary War advanced, these unconventional methods became a key component of the colonists' strategy, greatly impacting the overall trajectory of the conflict.
