I just kept moving away, the others also came but concentrated on an area a good way behind me.
I was on the free cam watching them DC an area I wasn't in, there were in the end 7 DD's plus at one stage an aircraft also bombed an area a good way from me.
The DD's eventually gave up and left the area, I surfaced when it was safe I never scored a hit but in a way I felt I did for evading all those hunters and got the crew home safe.

This leads me to a question, this was the first time I deployed decoys, so how far do they go to lead a DD to ignore you, how do they work?
I've seen them in modern sub movies but this is WW2 and in the sim they worked in this case anyway.

Edited to add:
I was in the Porpoise sub and the Japanese DD's seemed to be a few various types.

in SH4, a decoy will create a noise field over a given area at whatever depth you released it for a specific length of time. early in the war the area is smaller and the duration is less than later in the war.

in your story above, you did exactly what you are supposed to do: release a decoy, go a bit deeper, change course 90 degrees, and, of course, slow down.
