Off the thread sorry Neil.
My Mothers brother Ted was chief Engineer in the engine room on Atlantic crossings torpedoed twice.
On the first abandon ship he went down to rescue his mate Sparky who was trapped under a girder, chest deep water made it lighter and they were both out before it went down.
On the second it was an oil tankard listing badly after torpedoes and again the abandon thip went out and he went down and filled opposing tanks with water to right it, and it came hone,
No medals of course but the guy below deck saved a life and a ship !
