No, I didn't really understand that.
Suffice it to say that since I'm already fudging history as it is, we'll just have to say that the good people of AG Weser got her ready on schedule and my veteran crew managed to learn the Type IXC in less than a month. They er, trained on another one, or something. Yeah, that's the ticket! (The reason I took U-126 is that she's not one of the well-known boats and therefore I can more or less write her history, as opposed to Kptlt. Bauer.)
Meh, I'll not make these mistakes again when it comes time for the GWX career.
Thanks for your help---I appreciate it. I may have learned a few things from this.
