Truant's torpedo caused major midships flooding and disabled Karlsruhe's engines and electrical generators, including much of the power needed to control the incoming water. Placing machinery low inside the hull offered protection during surface action, but primary and backup generators shared the same flooding vulnerability. In this interpretation, the loss of institutional memory after the Treaty of Versailles left German designers relearning damage-control lessons. Karlsruhe remained afloat for roughly two hours before an escort removed her crew and fired two torpedoes to scuttle her. An official report argued that a forward pump retained power and that towing might have been possible. The large inflow of water, limited subdivision, and worsening stability nevertheless provide grounds for defending the decision to abandon her.

Karlsruhe's flooded generators and the scuttling decision
Karlsruhe lost engines, generators, and pumping capacity after one torpedo hit, leaving a disputed choice between towing the damaged cruiser and scuttling her.
