Surface Surprise. Good tactic against light escorts.

Yeah...the mods have absolutely no bearing on patrol grid allocation. It tends to happen randomly and that's just one of many reasons I use SH3Commander (to enable me to change the grid)

I found a list of all HMS Storm's surface actions in uboat.net. The surface action I was talking about is the noted under the 23th July entry. Note the two escort ships sunk by the british submarine in that battle:

Also note that Lt. Young conducted an attack against one U-boat sent to resupply the monsun boats based at Penang (The action is described in the book, but it's not said that it was a german U-boat, I didn't know this)

Is there any indication of what types the two patrol vessels were? How were they armed.

An interesting discrepency. I'm not saying it means anything, as I have found many different reports that don't always match other reports; as I say, it's just interesting:

14 April 1944:
Indian Ocean. Arrives at Port Blair, Andaman Islands. Unloads. [1]

Author's Note:
[1] Some sources claim W-7 was attacked by Royal Navy (Volunteer Reserve) LtCdr Edward Young’s submarine HMS STORM and sank at 11-34N, 93-08E.

Also, looking at various ship sinking lists, I've found 3 other Kiso Marus, one sunk by US aircraft, one sunk by USS Bonefish and the third sunk by USS Tinosa. I'm trying to find out why so many ships had the same name.
