Camp photograph of the 13th Illinois Infantry, also known as “Fremont’s Grey Hounds,” at Helena, Arkansas; while the photograph is undated, the 13th Illinois was camped at Helena from July through December 1862. The trees in the background indicate the photograph may have been taken that fall. The 13th Illinois left Helena to participate in the attack on Chickasaw Bayou, north of Vicksburg, Mississippi that December. The unsuccessful assault resulted in heavy losses, including the regiment’s colonel, John B. Wyman.
