text_A: At the outbreak of the American Civil War, "Opothleyahola" refused to form an alliance with the Confederacy, in contrast to many other tribes, including many of the Lower Creeks. Runaway slaves, free blacks, Chickasaw and Seminole Indians began gathering at Opothleyahola's plantation, where they hoped to remain neutral in the conflict between the North and South. On August 15, 1861, Opothleyahola and tribal chief "Micco Hutko" contacted President Abraham Lincoln to request help for the Union loyalists. On September 10, they received a positive response, stating the United States government would assist them. The letter directed Opothleyahola to move his people to Fort Row in Wilson County, Kansas, where they would receive asylum and aid. They became known as Loyalists, and many were members of the traditional Snake band in the latter part of the century.
text_B: Might the Confederacy have counted on all the Lower Creek tribes to help them in their fighting?
