The reasons the colonists won the Revolutionary War include:
B: They understood the local geography - The colonists had a better knowledge of the terrain, which helped them in battles.
E: France and Spain provided support - Both France and Spain offered crucial military support, supplies, and resources to the colonists, significantly aiding their efforts against the British.
A (they had more and better supplies) and D (they had more experienced soldiers and officers) are generally not considered accurate statements regarding the advantages the colonists had compared to British forces.
C (they relied heavily on the Native Americans for support) is also not entirely accurate, as Native American tribes had varying allegiances, and their support was not uniform or decisive for the colonial cause.
In summary, the key factors leading to the colonists' victory were their understanding of the local geography and the support from France and Spain.
