What sort of toys they had?

Not necessarily. I have discovered that occasionally the escorts randomly ping just to check if anything is around, and even though your hydraphone man starts saying we've been detected, it is not necessarily so. Unless the escort starts making a run on you, you may still be undetected and safe.

If an escort is closing on you, you must fire from further than 300 metres away. The torpedo must run 300 metres in order to arm; if you fire at 300 metres on a destroyer that is closing on you, the torpedo will arrive at the destroyer before it has run 300 metres, due to the closure rate.

You've probably come across the 'Creeping attack' tactic..

3 or more scorts attack you in sequence.

a) One ship sits a distance from you, locking you in it's ping bracket.
b) One other ship has passed and slowing down to take up a)'s position.
c) The third ship is coming in for the attack, by getting location information from a)

To counter this 'mass' attack I used to...
Sit at the hydrophone the whole time.
You just avoided b) so you have him 'on view'
a) is moving slow enough to be heard on hydrophone. Keep his bearing - you need this.
c) you can also hear, and as he starts to speed up, you flank speed towards a).. YES - flank speed towards a)

What this does.. if you time it right, you'll pass under a) just before c) gets on top of you. This creates a bit of an AI dilema for a) and c).
a) cannot drop DCs as it's moving to slowly and will blow itself up
c) cannot continue the chase or drop DC's as it will ram a) and also blow both of themselves up.

This leaves a) and c) literally stationary and out of position for valuable minutes. Now you head directly away from b)'s projected position in silent mode/speed once again.

This can go on for hours, but I eventually had the two ships ram each other. and the 3rd gave up the chase. Depth used was maximum and no less.
