Random Pearl Harbor stuff...

This has nothing to do with the island hopping, but i just read an article on the Pearl Harbor attack from the Japanese perspective. Apperantly Japan did not only have airplanes during the attack. There were 5 submarines that were not detected by radar that sunk ships from underneath. Throughout the course of time, four out of the five Imperial subs have been discovered, but one was not! If you look into it, there is a screenshot that you can find( note it will take some time) of the last, missing submarine. I thought it was interesting so if you are bored, look it up. This is one of the subs.
