Sheridan's campaigns

After the Civil War, all of the Indians were assigned to reservations, and the reservations were under the control of the Interior Department. Control of the Great Plains fell under the Army's Department of the Missouri, an administrative area of over 1,000,000 mi encompassing all land between the Mississippi River and the Rocky Mountains. Maj. Gen. Winfield S. Hancock had led the department in 1866 but had mishandled his campaign, resulting in Sioux and Cheyenne raids that attacked mail stagecoaches, burned the stations, and killed the employees. They also raped, killed, and kidnapped settlers on the frontier.

Philip Sheridan was the military governor of Louisiana and Texas in 1866, but President Johnson removed him from that post, claiming that he was ruling over the area with absolute tyranny and insubordination. Shortly after, Hancock was removed as head of the Department of the Missouri and Sheridan replaced him in August 1867. He was ordered to pacify the plains and take control of the Indians there, and he immediately called General Custer back to command of the 7th Cavalry; Hancock had suspended him.

The Department of Missouri was in poor shape upon Sheridan's arrival. Commissioners from the government had signed a peace treaty in October 1867 with the Comanche, Kiowa, Kiowa Apache, Cheyenne, and Arapaho which offered them reservation land to live on along with food and supplies, but Congress failed to pass it. The promised supplies from the government were not reaching the Indians and they were beginning to starve, numbering an estimated 6,000. Sheridan had only 2,600 men at the time to control them and to defend against any raids or attacks, and only 1,200 of his men were mounted. These men were also under-supplied and stationed at forts that were in poor condition. They were also mostly unproven units that replaced retired veterans from the Civil War.

Sheridan attempted to improve the conditions of the military outpost and the Indians on the plains through a peace-oriented strategy. Toward the beginning of his command, members of the Cheyenne and Arapaho followed him on his t

ravels from Fort Larned to Fort Dodge where he spoke to them. They brought their problems to him and explained how the promised supplies were not being delivered. In response, Sheridan gave them a generous supply of rations. Shortly after, the Saline Valley settlements were attacked by Indians, and that was followed by other violent raids and kidnappings in the region. Sheridan wanted to respond in force but was constrained by the government's peace policy and the lack of well-supplied mounted troops. He could not deploy official military units, so he commissioned a group of 47 frontiersmen and sharpshooters called Solomon's Avengers. They investigated the raids near Arickaree Creek and were attacked by Indians on September 17, 1868. The Avengers were under siege for eight days by some 700 Indian warriors, but they were able to keep them at bay until military units arrived to help. The Avengers lost six men and another 15 were wounded. Sherman finally gave Sheridan authority to respond in force to these threats.

Sheridan believed that his soldiers would be unable to chase the horses of the Indians during the summer months, so he used them as a defensive force the remainder of September and October. His forces were better fed and clothed than the Indians and they could launch a campaign in the winter months. His winter campaign of 1868 started with the 19th Kansas Volunteers from Custer's 7th Cavalry, along with five battalions of infantry under Major John H. Page setting out from Fort Dodge on November 5. A few days later, a force moved from Fort Bascom to Fort Cobb consisting of units of the 5th Cavalry Regiment and two companies of infantry, where they met up with units from the 3rd Cavalry leaving from Fort Lyon. Sheridan directed the opening month of the campaign from Camp Supply. The Units from the 5th and 3rd Cavalry met at Fort Cobb without any sign of the 19th Kansas, but they had a lead on a band of Indians nearby and Custer led a force after them.

Custer's force attacked the Cheyenne Indians and Black Kettle in the Battle of Washita River, and an estimated 100 Indians were killed and 50 taken prisoner. Custer lost 21 men killed and 13 men wounded, and a unit went missing under Major Elliott's command. Custer shot 675 ponies that were vital for the Indians' survival on the plains. Immediately following the battle, Sheridan received backlash from Washington politicians who defended Black Kettle as a peace-loving Indian. This began the controversy as to whether the event was best described as a military victory or as a massacre, a discussion which endures among historians to this day.

Following Washita, Sheridan oversaw the refitting of the 19th Kansas and personally led them down the Washita River toward the Wichita Mountains. He met with Custer along the Washita River and they searched for Major Elliott's missing unit. They found the bodies of the missing unit and the bodies of Mrs. Blynn and her child who had been taken by Indians the previous summer near Fort Lyon. The defeat at Washita had scared many of the tribes and Sheridan was able to round up the majority of the Kiowa and Comanche people at Fort Cobb in December and transport them to reservations. He began negotiations with Chief Little Robe of the Cheyenne and with Yellow Bear about living on the reservations. Sheridan then began the construction of Camp Sill, later called Fort Sill, named after General Sill who died at Stone River.

Sheridan was called back to Washington following the election of President Grant. He was informed of his promotion to lieutenant general of the army and reassigned from the department. Sheridan protested and was allowed to stay in Missouri with the rank of lieutenant general. The last remnants of Indian resistance came from Tall Bull Dog soldiers and elements of the Sioux and Northern Cheyenne tribes. The 5th Cavalry from Fort McPherson were sent to handle the situation on the Platte River in Nebraska. In May, the two forces collided at Summit Springs and the Indians were pursued out of the region. This brought an end to Sheridan's campaign, as the Indians had successfully been removed from the Platte and Arkansas and the majority of those in Kansas had been settled onto reservations. Sheridan left in 1869 to take command of the Army and was replaced by Major General Schofield.
