Can you break off a couple infantry and artillery to capture all the other Russian territory? Then he has to come out and fight. If you have Leningrad and Stalingrad you’re doing pretty good. If you get enough of his territory you may be able to keep him bottled up for quite a small investment.
So in the manual it states that defending carriers planes are considered to be defending in the air. It also states that units trapped on a damaged carrier cannot participate. I was always under the assumption that when a sub attacks a loaded carrier that… 1) if it only scores one hit and damages carrier then the planes are trapped until it can get back to a friendly naval base 2) If it scores two hits then carrier and all cargo are lost since they don’t participate in battle against subs w/o a destroyer present. If this is not the case then it seems to me that there is no way for cargo to get trapped on a carrier?
My most recent Europe game saw Denmark being vital for the US to take and hold Norway, while the German’s had 4 transports in sz115 (Novgorod). Britain was able to take Denmark and West Germany. Then the US took Norway, and blocked the German navy with a DD at 114 so that the German’s could not conduct an amphibious landing. This worked to secure the Norway Major factory at a cost of only 3 US DDs over 3 turns (I sent my land units to Denmark instead of Norway to help the British hold it). Which then permitted the combined allied surface fleet to sail towards the Mediterranean and convoy Italy.
