That summer, while the Union celebrated its victory, the plains were in turmoil. The Santa Fé and Overland trails were closed, and virtually every plains tribe was at war with the United States. As federal troops began to re-occupy their posts in Texas, the Great Plains and Indian Territory, government commissioners met with the plains tribes in October on the Little Arkansas River near Wichita to arrange a peace. The Little Arkansas Treaty gave the Comanches and Kiowa western Oklahoma, the entire Texas Panhandle, and promised annuities of $15 per person for forty years.
