What does Black Hawk's statement suggest about Native Americans' level of trust toward the federal government?

This famous Native American Indian Chief, had led his warriors to victory during war times as well as politically. His famous quote "You have taken me prisoner with all my warriors. I am much grieved, for I expected to hold out much longer

and give you more trouble before I surrendered." depicts that his trust cannot be gained quickly because of the political crisis he had with the treaty at the time.
