Well it was a trap and they did kill all the troops. Pretty sure that meets the definition of a massacre.
Some people want to put all 'white' colored people on one side, and 'indians' on the other side.
These people don't care about history or facts.
so group of people ' a ' like to go murder , rape and torture people ' b ' ,
People ' b ' aren't vicious enough or numericaly strong enough to defend themselves from 'a'
Then one day people 'c' come on the scene, they are migrating the same as all the other groups of people have, everyone here migrated from somewhere else.
People 'c' are strong and concerned about being fair to their neighbors, so people 'b' join into a treaty seeking, amount other things, military protection.
People 'a' also joined into the peace treaty, then, broke the treaty themselves,
they broke their own peace treaty with other tribes, their own tribe, and the usa, then spent the rest of their lives claiming that they were cheated
