Answer:
The answer is below
Step-by-step explanation:
The cooperation from European allies was crucial in American victory in the Revolution against Great Britain.
This can be seen on the part of France, which aside from supplying the Continental Army things like gunpowder, cannons, clothing, and shoes generally, also assisted to strengthen the continental army at the final battle of Yorktown in 1781.
The Spanish as well having officially declared war on Britain in 1779 ultimately attacked British forts in places like Florida, Alabama, and Mississippi.
Similarly, the Netherlands provided financial loans to the United States to fight Great Britain.
All these alliances stretched the power of Great Britain in fighting on many fronts at the same time, thereby reducing their powers and eventually led to the victory of American Colonists.
