Where should I dock?

[The_Blockade_Runner]

Running GWX 2.O, First flotilla type VII b, it was July 1940 and France had just fallen,I was south of Ireland and didn't want to make the trip back up around England to Kiel to resupply when I knew the base would be moving soon. So I resupplied in Vigo Spain, I was awarded the renown for the patrol but coud not award medals or promotions because I was not in base. So after I resupplied a month passes by in the Spanish port before the next patrol. I headed off to the BE grid to make trouble. Now its September 1940 and my fuel is good but I need to resupply ammo, Attacked the same convoy 2x with good results. The problem is my orders under briefing still tell me to return to Kiel. And Ive never recieved a radio message saying the base was change to brest/ Only that a new base was available in brest. I want to dock in Brest but I don't want to miss out on recieving medals again. What should I do?
