A Question about GWX 3.0 Radio Messages

[Joefour]

Hi All,

I'm running GWX 3.0, it's February, 1940. I'm SW of Ireland, merrily sinking all of the soft targets I come across. I get a series of several messages from BDU ordering me and a couple of other boats to station ourselves in several different locations near the western approaches to the Channel, and to expect the Ark Royal to come through somewhere in the area. I ignored these messages because I wasn't sure (even though supplied with Long. and Lat.), exactly where they wanted me to be. When I finally expended all my torps and came home, I got awarded the Knight's Cross! Obviously the brass were not too irritated with me for ignoring orders. I also tend to maintain radio silence while I'm out there wreaking havoc with Winston's ships.
My question is for future reference: If I had figured out the correct area to be in as given by the radio messages and actually had gone there, would I have had a chance at getting the Ark Royal in my sights? When the messages came in, no markers or anything like that showed up on the tactical map, par exemple, "task force headed east at 12 Kts." or "Neutral warship in zone such-and-such heading SW, fast".
Any ideas? Has anyone else experienced something similar? I'd love to be able to fire off a salvo at a target like that some time.
