While surfing the web for submarine information I ran into information on the sinking of the ship SS Wilhelm Gustoff. I was a bit surprised that this was the largest loss of life in a maritime disaster and has had very little press related to it.
The submarine responsible for the sinking was the Russian S-13, which I believe was a type XXI. Has anyone researched this incident? Also is anyone aware of english books on the topic. There appears to be agreat deal of mystery related to the sub and ship.
