I think there is absolutey an argument that good decorum would have provided a nearby surface vessel to assist with rescue. But not being nice in a war isn't the same as a war crime. And expanding the notion of war criminality to cover even breaches of decorum fundamentally waters down a term that has already started being seen as meaningless because people want to make it apply to any act of war.
