Explanation:

First of all, we have to understand the context of war, the arrival of American forces and their actions,

In the first place, the war was mature by the time Americans got involved in the war. They started by economic procedures and then reinforced their actions with military intervenience. In the second place, the American army arrived when the war had 3 years old. They didn't replace Britain or French armies, they reinforced heir forces to strike harder and were a definitive impulse that they needed.
