What is calvary shells?

Calvary shells are small, cylindrical metal containers that were used during the American Civil War to transport musket ammunition. These shells were typically made of brass or copper and were designed to be worn on a soldier's waist belt or thrown over his shoulder, allowing quick and easy access to ammunition during battle. Some calvary shells were also equipped with a hook or loop that allowed them to be attached to a horse's saddle for cavalry soldiers. Calvary shells were a popular and practical accessory for soldiers, and many examples can still be found in museums and collections today.
