What is the standard name for the April 19, 1775 opening engagement of the American Revolutionary War in Massachusetts?

The April 19, 1775 opening engagement of the American Revolutionary War is known as the Battles of Lexington and Concord.

British troops marched from Boston toward Concord to seize colonial military supplies and to capture Patriot leaders John Hancock and Samuel Adams. Colonial riders, including Paul Revere, helped spread the warning that British regulars were advancing.

The first clash occurred at Lexington, where Massachusetts militia met the British force. Fighting then continued at Concord, including a confrontation at the North Bridge, before the British column began its return to Boston under sustained attacks from colonial militia.

The name refers to two connected Massachusetts locations rather than a single battle at one site. The fighting transformed political resistance into open warfare and began the Boston campaign of the Revolution.
