pits at the base of Missionary Ridge. However, once they achieved their objective, four divisions (one led by Philip H. Sheridan) stormed up the ridge and routed the Confederate center. When Grant angrily asked who had ordered those troops up the ridge both Thomas and Gordon Granger, a corps commander in the army, responded they did not know. Granger then added, "Once those boys get started, all hell can't stop 'em." After Grant's victory at Chattanooga earned him promotion to general-in-chief of the U.S. Army, Maj. Gen. William T. Sherman assumed command of Grant's Military Division of the Mississippi, which controlled all Union armies in the West. He created an "army group" of the Army of the Cumberland, the Army of the Tennessee, and the Army of the Ohio and marched towards Atlanta in May 1864. On the way to Atlanta they fought in many battles and skirmishes including the Battle of Kennesaw Mountain. In September, Atlanta fell to Sherman's army group. When Confederate general John B. Hood moved north from Atlanta, Sherman chose not to follow him and instead dispatched some of the Army of the Cumberland (IV Corps and Provisional Detachment) and the Army of the Ohio (XXIII Corps) after him. Thomas finally met Hood at the Battle of Nashville and crushed him, thus bringing to an end any significant military actions for the Army of the Cumberland. Other elements of the Army of the Cumberland (the XIV and XX Corps) marched to the sea and north through the Carolinas with Sherman, under the command of Maj. Gen. Henry W. Slocum. These forces became the Union's Army of Georgia and participated in the Grand Review of the Armies in Washington, D.C., before President Andrew Johnson in 1865.
