Later that year, on September 19, Grant's army defeated Confederates at the Battle of Iuka, then successfully defended Corinth, inflicting heavy casualties. On October 25, Grant assumed command of the District of the Tennessee. In November, after Lincoln's preliminary Emancipation Proclamation, Grant ordered units under his command to incorporate former slaves into the Union Army, giving them clothes, shelter, and wages for their services. Grant held western Tennessee with almost 40,000 men.
