Ah, there's the nickname... my memory works great sometimes. He was shot in an open car, as you noted, seriously (indeed, fatally) wounded, and the attackers had fled. The locals refused to help him, and he did ask. That detail is probably what sent Der Effer to the boiling point. Everyone in the town was killed, and I think the whole place was burned down. The commandos were trained by the British, having been smuggled out and smuggled back for the attack.
