Wow, 4 battleships for Germany. That sounds so cool, but I agree with Young Grasshopper, it sounds like you have left yourself very weak in other areas. Still, I would love to see Germany with 4 battleships. Of course, I have always been partial to the Bismarck.
As for attacking England, how much of your Luftwaffe do you still have. With 6 transports you could hit England with 12 land units against Britains 15 infantry. If you still have a lot of Luftwaffe to counter the 6 RAF planes, you could probably take England. However, Captainhook is also right, Russia is probably getting ready to invade you. Hope you got enough men to repel them.
