US Navy 24-Pounder Dahlgren Boat Howitzer at Shiloh

US Navy 24-Pounder Dahlgren Boat Howitzer Number 656 is displayed at Shiloh National Military Park. (Many thanks to James Murray for sharing these photos with us!) It was cast in 1864 by Ames. As manufactured it weighed 1305 pounds. This boat howitzer has a portion of its hammer still in place - and a something (a projectile?) lodged in the tube.
