A bit of a problem

[manucapo]

ok ive got myself into a big problem, i was between borneo and java
and those are really shallow waters, and i get this report of a task force heading right for me (not for me , in my direction)
so i was in very shallow water and right infront of the task force, it was preety big
the biggest ive seen yet, they where going in two lines,
and i was right in the midlle ,
i waited, raised my periscope, worked out the bearing and speed on a heavy cruiser, and fired all my 4 torpedoes (im a class s), i hit 3 of them and it goes down
but now im trapped in shallow water right in the middle of an enemy task force








so what do you guys say i should do, try to sneak out at 1-3 speed, run flank speed for the next deep water, wich is not very far away,
or sink to the bottom and stay there.
id like to know what you guys think
