Pariscope depth evasion works!

I was near the sub base above scapa flow when I was forced under by some nosy escort. I went silent and he passed but as soon as I surfaced I was 300 meters from another one that came in undetected! To late to dive again before he spotted me I made a break for it and took a few light hits as I dived again beneith the waves.
He closed quickly and laid a salvo of DC's that I thought would be my end but, He laid them to deep and I was only forced to the surface from their detonations. Well again i took light hits while my sub resettled to Pariscope depth.

I tried all the tricks but with only 14 meters below me at periscope depth i had few options. I went as low as i could, I used bursts of speed after each pass to try and get some distance to no avail. His sonar would find me every time. Finally he straddled my boat and did some heavy damage. So I took her off silent running and had a repair team hitting the problem at full force while I bought a little time by using flank speed to distance myself before his next run. I noticed that every run he was dropping his cans to go off a little deeper than I was so, I after I repaired I went shallow. Just then I noticed another destroyer showed up to the party!

I figured at Periscope depth I could blow ballast and save the crew if nothing else.
Then something odd happened. Even know he was at fairly close range and coming at my port side almost 90 degrees he lost me and began to circle looking for me. He went right over my port bow just missing the conning tower and he never dropped a can.
slipping away at two knots many times he was so close he passed right over my stern but he didnt dop any cans! He was pinging like mad but never picked up my scent. Both destroyer circled wildly looking for their easy kill dropping randomly as I just gave up evading and headed due east w/ silent running. i sliped away easily to 1,500 meters than sat for 9 hours until it was dark enough to surface and run for it. In the end I made it and the point is no matter what depth I was at or what angle that destroyer always pinged me and did a run.
But as soon as I was near the surface he went blind. That matches w/ what many U-boat capitans claimed to have done to avoid ASDIC. Also note that the seas were very rough during this and I doubt it would have worked as well in nice weather.
