In the battle of Palo Duro Canyon many hundreds of Indian horses were killed by the US Calvary and later around World War I the bones of the Indian horses were removed why?

In the Battle of Palo Duro Canyon, many Indian horses were killed by the US Cavalry to disrupt the supply lines and mobility of the Native American tribes. Later, around World War I, the bones of these horses were removed to clear the area for military training purposes and to utilize the land for more practical uses. This action reflected a broader trend of repurposing lands previously associated with Native American conflicts for military and agricultural development in the United States.
