Pegram's battery and the Eighteenth and Twenty-second South Carolina lost 278 men killed and wounded. But the men on the right and left rallied in the face of this great explosion of 8,000 pounds of powder, and instead of the capture of the crest in the rear of Johnson's line and the fall of Petersburg, Burnside sustained defeat and heavy loss.

Shepard; the Fourteenth, Maj. James H. Johnson; the Seventeenth and Twenty-third, Col. Horace Ready; the Twenty-fifth
