I'm not saying you're wrong, but I've not read any reports of an unexploded torpedo punching through the hull. Must have happened sometimes I suppose.

More common in the reading I've done is the air flask rupturing. The dud torpedo broke apart as the result of the impact, and it would appear like a low order detonation, but was just the torpedo rupturing. One of the V-boats for instance had this happen at Midway when she fired on a carrier, Kaga? The flask was then used as a life preserver by the carrier's crew, meaning this attack did more to save the Japanese than to harm them.

I've been reading through the Japanese convoy log Donner sent me, and surprisingly there were indeed flooding incidents caused by dud torpedoes. So far I've encountered only one that actually sank from that. Of course one is more than enough to get my attention.

At the other extreme I've found one incident in which a perfectly normal 9,815-ton cargo ship took six torpedoes and five hours to sink!

That's the one. Couldn't remember the name so I left it out.

Do you guys know of any specifics on attacks where an unexploded torpedo sank a ship? Which sub was involved, which target? Or date maybe?

I have that info at home. I'll try to post it tomorrow.

From the book Submarine Diary by C. Mendenhall.

"..in late 1943 Hallibut sank a ship simply because wo dud torpedoes punched 21"inch holes in the side of a freighter.."

I am currently reading above book and when reading this about Hallibut I used that info the check the book "US Submarine Attacks During WWII" by John D. Alden. But unfortunately it did not any ships sunk in 1943 by Hallibut with duds :-(

I'm temporarily unable to access any of my files, but I definitely did set aside the info from one ship that sank from a dud and two more who barely escaped that fate.

Sometime in the future I will post it. It's real.
