I was just reading about the sinking of the CSS Albemarle during the civil war. After the vessel was sunk, it was then raised again by the Union Navy. Although the vessel sunk in shallow water with the upper parts of the ship still above water, the hull was badly damaged from a spar torpedo attack. That got me wondering: how would they have raised the ship without modern cranes and stuff on other ships and how did they get it back to land to fix it?
