Taken from the article Civil War Bands and their Music.
Performing under fire became commonplace for bands under the command of General Philip H. Sheridan. Sheridan loved music and took a personal interest in his bands. This was shown in the equipment, mounts, and uniforms he accorded his bandsmen. To pay for these privileges, his bands performed at the front during battle playing the liveliest airs in their repertory.
At Dinwiddie Court House, Sheridan massed all his musicians on the firing line with the order to "play the gayest tunes in their books .... Play them loud and keep on playing them, and never mind if a bullet goes through a trombone, or even a trombonist, now and then." General Sheridan paid tribute to Army bands when he remarked, "Music has done its share, and more than its share, in winning this war."
