Final answer:
The American victories in the Battle of Saratoga and the Battle of Yorktown were significant Eastern victories during the American Revolutionary War. Saratoga was the turning point that secured French support, while Yorktown marked the end of the war with the British surrender.
Step-by-step explanation:
During the American Revolutionary War, the American forces won significant victories in the East. Specifically, they achieved victory in the Battle of Saratoga and the Battle of Yorktown. The Battle of Saratoga comprised two significant fights in 1777. Initially, the British were victorious under General Burgoyne's command; however, the tables turned when American forces rallied, pushing Burgoyne back, leading to a British retreat.
This inspiring American triumph encouraged other nations, particularly France, to form alliances with the revolutionaries. The Battle of Yorktown, on the other hand, concluded with the ultimate surrender of British forces in 1781, effectively ending the war. The turning point of the war is often attributed to the victory at Saratoga, as it resulted in increased morale among the American forces and secured French support both financially and in terms of military aid. French assistance included the provision of gunpowder, money, soldiers, and naval forces, significantly aiding the American cause.
The French also sent military leaders such as the Marquis de Lafayette, who became an essential figure in the war effort. The support from France was instrumental in challenging British dominance, ultimately leading to the successful bid for American independence.
