Most indigenous people did not participate directly in the war, except for warriors and bands associated with four of the Iroquois tribes in New York and Pennsylvania which allied with the British. The British did have other allies, especially in the upper Midwest. They provided indigenous people with funding and weapons to attack Continental Army outposts. Some indigenous people tried to remain neutral, seeing little value in joining what they perceived to be a "white man's war", and fearing reprisals from whichever side they opposed. The Oneida and Tuscarora tribes among the Iroquois of central and western New York supported the American cause. The British provided arms to indigenous people who were led by Loyalists in war parties to raid frontier settlements from the Carolinas to New York. These war parties managed to kill many settlers on the frontier, especially in Pennsylvania and New York's Mohawk Valley.
