Which battle is considered the first of the American Revolution where colonial forces were initially forced to retreat but later regrouped?

The Battle of Lexington and Concord is recognized as the first conflict of the American Revolution. On April 19, 1775, British troops aimed to seize colonial military supplies stored in Concord. The colonial militia initially faced a surprise attack at Lexington, where they were forced to retreat. However, they regrouped and mounted a successful resistance against the British as they advanced to Concord. This ability to regroup and push back marked a significant turning point, igniting the Revolutionary War and demonstrating the determination of the colonial forces.

The other battles listed, while significant in the overall context of the American Revolution, do not fit the description provided. The Battle of Bunker Hill occurred later, in June 1775, and although it showcased colonial resilience, it was not the first battle. The Battle of Yorktown, in 1781, was the decisive victory that effectively ended the war, while the Battle of Saratoga in 1777 marked a turning point in favor of the Americans by securing French support.
