In April 1775, tensions between British colonists in the Province of Massachusetts Bay and the royal governor, General Thomas Gage, boiled over into war. When General Gage dispatched troops to Concord to search for military supplies the colonists had stored there, alarms were raised, and colonists and soldiers clashed in Lexington and Concord on April 19. Militia companies continued to arrive in the days following, and the British troops were besieged in Boston.
