To be honest ppk,you did pretty much what most of us would have done,and any attack you can sail away from is a sucess,you survived

thats the problem with the wars progression and the allies advantages,getting into good positions for convoy attacks starts to get really hard,frustrating and alot of the time down to sheer luck...and most of the time ,as you observed,pointless

there ability to detect you is so good that to have even an earthly's chance of sucess you really have to push yourself(and your crews) life expectancy to the limit,and I'm afraid for alot of the time for very little reward.I'm a big chicken Kaleun and I'm not prepared to take those chances so I get a big old TypeIX boot and go farther out to sea looking for single merchie's to sink,that way I might,MIGHT just make it to the end of the show!
