One Unlucky I-boat

[Atilla60]

June 18. 1942 (PBEM, me as Japanese)

It's been awhile since my subs achieved anything noteworthy. So I decided to revise their patrol zones in general.

In the vicinity of <classified>, I found I-160 patrolling at an remarkably low speed. Upon inspecting the boat, I was astonished to realize that it had some serious damages:
Sys 43
Flt 12 (5)
Eng 8 (2)
+ Deck gun destroyed

What puzzles me is, that in this particular patrol zone, there had been no activity whatsoever, not at any point.
I therefore decided to do a little detective work (thank god for WitpTracker and Combatreporter [:)])
It turned out that whatever happened, it happened on turn 171 (May 25. 1942). Almost a month ago - game time.
Scanning through the OP report for that day left me confused. On a lower level, but still.
The only thing mentioned in the report, indicating something (ASW?) is this line:

a Japanese SS is reported HIT

No name, no location - hooray for IJN communications [:D]

Now, I'm 99.9% confident that at no point during the combat replay, was there any messages, suggesting activity in that particular area. No sub attack, no ASW combat, no reports on accidents aboard. Nothing, nada, zip.
Otherwise I would have been aware of the boat's condition, as I always, with no exceptions, check a TF if it has been spotted or, as in this case (probably), subject for an ASW attack.

Anyway, for now I'm filing this under "Stuff that happens", but I would like to hear if any of you guys have similar experiences.

Besides, this is not the first time I-160 is in trouble. I remember, and Tracker supports, that earlier in 1942, during the Sumatra invasion, I-160 was heavily damaged while on a mine laying mission Off Soerabaja. Also in this case there's no mentioning in the OP report of what happened.
It was the same skipper though (Nav 70 - Agr 66).
Scratching my head..... Can an aggressive commander provoke accidents?

Any thoughts?

Guess an enemy ASW plane spotted it and attacked, no combat replay on those... I think that's it.

Probably Air ASW. You should get in the habit of going to your ship list screen and filtering out all other ships but subs and then click on the flotation tab. The ones with the most damage will move to the top. Do this at least every other turn. (I do it every turn). A lot of subs can get damaged and you won't notice it. This way you can find the ones that need to be sent home.

maybe, if it was too far away from a coast to get damaged by LBA Air ASW, could be a lucky shot by a kingfinisher aboard an allied cruiser that was simply passing by...rare but happens

I have also had subs damaged like this. sometimes i wonder if its the obcure "marine obstacle"! that is mentioned in the rules but could also be a fp as mentioned above.

My guess it is was spotted and hit by naval search.

Naval search.

Thanks for the feedback guys.

I gave it a good night's sleep and have landed on the same conclusion as seems to be the consensus here, air ASW.
Considering that the turn in question was run with the latest official patch, and the distance to the nearest Allied airbase (10-12), I'd say a TF passing by.
So until proven otherwise, the commander is off the hook. [:)]

I'm definitely making this my first thing to do each turn from now on. Thanks for the heads up.

Note that naval search is different from air asw.
