New Career
Leutnant z. S. Robert Buck commanding U-154, type IXC.
Short patrol. I wish we could get a radar warning set that would warn us before the aircraft are right on top of us! One lucky hit and we nearly drowned! Boys at the pen are fixing her up right now, and the officers and warrant officers are off gaining some qualifications. We gotta get the performance of this pig up or she's gonna get blown clean out of the water!
