The reason why the U.S. government asked the Five Tribes for a peace conference at Fort Smith in 1865 was to ask the tribes to repudiate their treaties with the Confederacy (B), as it was informed to the tribal delegates that the treaties signed with the Union before the Civil War were no longer valid and they had to negotiate new ones with the United States. The conference did not go well because the tribal delegates refused the new treaty stipulations and disagreements between loyalists and secessionists Native Americans hampered negotiations.
