His expertise significantly improved the effectiveness of the American forces. Steuben introduced a standardized system of training and drill, which included the use of the bayonet and proper formations. His efforts contributed to the success of the Continental Army, particularly during key battles such as Yorktown, ultimately aiding in the fight for American independence.
