Why did chief Joseph take the nez perce to Canada rather than fight the army troops?

Chief Joseph chose to lead the Nez Perce to Canada rather than confront the U.S. Army due to a desire to protect his people from further bloodshed and suffering. He believed that fleeing to Canada would offer them a chance for safety and freedom, as they sought to escape forced removal from their ancestral lands. Fighting would likely result in heavy casualties and a devastating loss for his tribe, and he hoped to find refuge with other indigenous groups in Canada. Ultimately, his decision reflected a strategic choice to preserve the lives and dignity of his people.
