The Saga of Col. Ulric Dahlgren's Leg-- Part 2: In A Cornerstone

At the time of his wounding, Ulric Dahlhren was a 20-year-old cavalry officer leading a charge through the streets of Hagerstown, Maryland,  when a Confederate shot  struck his right ankle and passed through his foot.  Three days later, he got home to Washington, but a fever set in and surgeons had to amputate his leg  just below the knee.

His father was John Dahlgren, who had recently been commandant of the Washington Navy Yard (but now commanded the South Atlantic Blockading Squadron trying to take Charleston, S.C.)  A new gun foundry was being built at the Yard.  The day after the amputation, an ambulance took the leg to the yard, and a Marine honor guard escorted it to the foundry where the building's cornerstone was about to be laid.

The leg was placed in a box, draped with an American flag and sealed inside the cornerstone.
