During which battle did the Colonial Army besiege the British with the aid of the French Army in October 1781?

The Colonial Army besieged the British at the Battle of Yorktown in October 1781 with significant support from the French Army. This battle was a crucial turning point in the American Revolutionary War, as it marked the last major military engagement of the conflict. The collaboration between American and French forces was vital for the success of the siege, effectively trapping British General Cornwallis and his troops on the Yorktown peninsula, limiting their escape routes by land and blocking them by sea. This strategic partnership not only showcased the growing alliance between the United States and France but also underscored the importance of international support in achieving American independence.

By successfully surrounding the British forces and launching coordinated attacks, the American and French troops were able to force Cornwallis to surrender on October 19, 1781, which led to diplomatic negotiations and ultimately the end of the war, reinforcing the determinative impact of the Battle of Yorktown in the struggle for independence.
