Battle Above the Clouds
a battle of the Civil War. The reference is to the storming of Lookout Mountain March 24, 1863. It was part of the general battle of Chattanooga. The Federals, under "Fighting Joe" Hooker, advanced up the northern slope of the mountain. All day the mists hid the valley below; and in the afternoon the clouds settled down so thick that the rattle of artillery ceased an hour for very darkness. Hence the name of "Battle Above the Clouds."
