Number one, nets and ropes over the side on the double. Make sure those in the water know there is a sub below them and look sharpish.
Engine room, all stop. Be ready to move on my order.
Depth chargers, stand ready.
Signals, alert convoy..

Yeah, that is what I thought, too.
Or just wait until the Sub moved away, attack, and take care of the survivors later after dropping them some life vests.

Why he had to attack right away in this situation is a bit odd, given a destroyer was able to maintain contact quite well when moving slowly. And especially given that a destroyer was able to detect the depths a U- Boat was operating in and as such would have been able to make a good judgement if to stop or move away.
A destryoers job, after all, was not to "sink" a sub in the first place, that was the hunter/killer groups task, but to force it to depths and as such make it impossible to catch up to the convoy for an attack.

In that this destroyer was already successfull.
