How Seydlitz's crew brought a wrecked battlecruiser home

Seydlitz returned from Jutland with so little buoyancy remaining that a large wave could have prevented her from reaching harbour. Her crew removed weight and kept the pumps running until the badly damaged battlecruiser was alongside. Once the pumps stopped, she settled immediately. Getting her home preserved a ship that Germany could eventually repair, although she could contribute nothing while that work continued.
