The failure of the US army to complete it's true objective (to capture Pancho VIlla), as well as garner support from the locals, and the failure of being an effective fighting force, saw that the US military was extremely unprepared and needed a re-work. This was especially true and the restructure direly needed in the rising tide of World War I.
This was put partially in place by declaring peace in the early days which allowed for the production of military hardware, as well as the slow process of training new troops, which was further sped up with the US inclusion into the world war militarily.
The battle in which the Native Americans attempted to resist the armed forces for the last time took place on 29th December 1890 in South Dakota near the Wounded Knee Creed.
It was the Masacre of Wounded Knee, also refered as the Battle of the Wounded Knee.
