Surface Mission 4, American in the gold edition - How?
 

Ok I admit I am a bit of a noob at this as I am stumbling on such an early mission. It is in the corvette and I have to sink two german subs. I sometimes get one, then the other one surfaces and sinks me, or they both sink me at the beginning or I dont get either of them with the depth charges and they both surface and sink me.

How the hell do I do this? Especially the sub hunting bit, its so hard? :damn:
