I took command of the USS Drum and on my first patrol I sank the Hiyo NW of Truk. The funny thing was that it only had one escort!
On my third patrol, I sank the Shokaku as it was sailing towards Bungo. The interesting part, No escorts!
It was pretty cool. I hit something important with my second torp and there were tons of secondary explosions and boy, did that carrier go down quick.
I'm running the latest version of TMO and RSRD.
I was just surprised that both CVs had no escorts.
