Encountered a Japanese task force outside Manila, with a cruiser and a couple of Kongo battleships.
Must've been spotted while diving by the lead destroyers, so I began diving, I was well deep and beneath the thermal by the time they were over me, but they still found me despite this. I had to take my boat, a Sargo class, well past 250ft (test depth), right down to 490ft, just shy of 500 before they lost me on sonar, and before I reached that depth I took some light damage and was rattled a bit by a few close cans.
Managed to evade the three destroyers and slip past, began rising upto PD and took shadow maneuvers against the lead Kongo. Got in right close upto PD at a distance of 800yrds.....given there was no time for proper speed calcs, I took a best guess and let loose all four forward torps, only for them all to miss and sail past the props of the Kongo as it accelerated away!!!!!, that or my quick map calculation of the AOB was a bit off, but i'm much more certain I fluffed the speed guess.
Can't believe it, to go through all that, all those angry depth charges, to come SO CLOSE to sinking my second battleship potentially in my entire SH career history (1, 2, 3 and 4), to fluff it on the speed guess!!!!
Was a heck of a thing though, yet I quit the game in disgust straight after those torps miss. I don't react well to such things!
EDIT: For the record, in my entire SH gaming career, through all of them (bar 5, don't like 5 at all) I have only sunk ONE battleship. And it was in SH4 in another game.....i've never sunk a carrier either. Pretty sad to admit that, after playing the SH series for so long!!
