Its Novemeber 1939 and i just started my campaign. Im in my 2nd patrol just west of ireland and i run tino my first convoy. Lots of ships and 2 escorts, a flower corvette and another little destroyer. I took a look at the flower corvette and it has hedgehogs?? Looks like it has radar too?? Now.. Reading "Hitlers Uboat War" i know that none of these advancements were ready in 1939, or maybe i ran into the expreimental corvette??? Anyway this is really weird. I expected to run into an auxilary ship escorting convoys in 1939. Oh well.. Guess ill have to fight thru it..
