Native American Sharpshooters in the Civil War-They neither spoke nor moaned, but suffered and died, mute in their agony. 
More than three thousand Native men were enlisted in the Federal army. The Confederates enlisted many more in Missouri, Arkansas, and Texas. In the Federal army the men were used as advance sharpshooters and rendered meritorious service. This photograph shows some of the wounded Native American sharpshooters on Marye’s Heights after the second battle of Fredericksburg. A hospital orderly is attending to the wants of the man on the left, and the wounds of the others have been dressed. In the entry of John L. Marye’s handsome mansion close by lay a group of four Indian sharpshooters, each with the loss of a limb—of an arm at the shoulder, of a leg at the knee, or with an amputation at the thigh. They neither spoke nor moaned, but suffered and died, mute in their agony.
