Colonial forces communicated during the battles of Lexington and Concord primarily through couriers and messengers.

This system allowed them to rapidly disseminate crucial information about British troop movements and coordinate responses among different militias. Local leaders relied on trusted individuals to carry messages across towns and communities, ensuring that militias could prepare for the impending conflict. Notable figures like Paul Revere famously rode to warn colonists of the British advance, exemplifying the importance of swift communication in rallying support and organizing resistance against British forces, which proved vital in the early stages of the American Revolution.
