1st campaign, 1st mission
 

I am to patrol AN51 it is Sept. 1st 1939. Two days later, Sept. 3rd at around 10am, I see a contact in my nav map, which I am tracking to intercept. But I have not receive orders from BdU yet to start operations?! Do I need to wait for the message, or can I get a go at it?

Shadow it.....orders will come soon enough!

Yeah, they come sometime that day. No need to worry. Unless of course he's a neutral. I think most of that first day they only mention attacking British.
