Casualties for the Battle of Lookout Mountain were relatively light by the standards of the Civil War: 408 Union, 1,251 Confederate (including 1,064 captured or missing). Sylvanus Cadwallader, a war reporter accompanying Grant's army, wrote that it was more like a magnificent skirmish, than a major battle. General Grant, whose focus was on the northern end of Missionary Ridge—and who was usually partial to the achievements of his key subordinates in the Western armies—later denigrated Hooker's achievement, writing in his memoirs, The battle of Lookout Mountain is one of the romances of the war. There was no such battle and no action even worthy to be called the battle on Lookout Mountain. It is all poetry. Nevertheless, the action was important in assuring control of the Tennessee River and the railroad into Chattanooga and endangering the entire Confederate line on Missionary Ridge. Brig. Gen. Montgomery C. Meigs, quartermaster general of the Union Army, observing the fog-shrouded action from Orchard Knob, was the first writer to name it the Battle Above the Clouds.
