According to Kemp in his book HM Submarines, two VCs were earned in the Med. when a British sub (Thrasher I think) surfaced to find two DCs on the deck. The first Leutenant and a Chief Petty Officer volunteered to to get them off. The first could be just rolled over the side. The second was caught between the pressure hull and the outer skin. The two men had to slip inside the space and push/pull the thing out. They were squeezed at full stretch and apparently the DC made some very alarming noises has they got it out. The officer then noted down the details on the outside of it before disposing of it. Took about 20 mins as I recall, and all the time off an enemy shore. Had the enemy shown up, the captain would have to crash dive, drowning the men.
I think they'd have preferred the SH3 version of it disappearing by magic!
