"The Indians kept increasing in numbers until it was estimated that we were fighting from 800 to 1,000 of them"

This quote by Buffalo Bill is referring to a battle in between Native Americans and the United States armed force. It is likely that the battle belonged to the Indian Wars, which were a series of disputes between the United States government and Native American tribes in the 19th century. The quote suggests that the Native Americans were greatly outnumbered by the United States military, as Buffalo Bill approximates that there were 800 to 1,000 of them. This suggests that the US military had a much bigger force, and that the Native Americans were at a downside. The quote also suggests that the Native Americans were able to increase their numbers throughout the fight, which might have been because of reinforcements or a rallying of forces. This could have signified resilience and decision on the part of the Native Americans, as they had the ability to increase their numbers regardless of the odds being against them.
