Answer:
One effect of the battles fought on the western frontier during the American Revolution was that bitterness and spitefulness between white colonists and Native Americans increased drastically.
Step-by-step explanation:
When the white colonists increased their exploitation, native Americans were far from friendly with their hosts. They were tired of being exploited, their land was taken from them and were forced to pay for the natural resources they once enjoyed freely.
The anger that was felt by the Native Americans was unimaginable. They had lost their homeland, the aggression was very well deserved towards the white colonists.
