I decided upon the Osaka area as a place to have a look at first. After skirting round a very tempting convoy in the mouth of the area I scouted around all the ports but didn't find anything until Kobe. I came upon heaven itself. Outside the bay were a Kongo class, Ise class and another Shokaku carrier.
Shokaku:
When I edged closer to line up for the Shokaku I discovered more inside the harbour area itself. There was another Shokaku and a Hiryu carrier inside!
Shokaku #1 going down:
I then headed in to the harbour and lined up all my tubes for the two carriers...
Shokaku #2 going down!
Hiryu is added to the list!
I then circled round the north end of the harbour and lined up for what would be a pain in the back side of a ship, the Ise.
Two torpedoes went flying and made good hits.
Didn't sink,

so another was let loose...
Shallow waters are a pain!
I circled round to fire my last torpedo and that finally finished her off!
Once I've returned to base, I fully expect a Life Presidency and the Japs to surrender within a day.
