Actually, England will always lose because Germany has enough there to stop 4 American Transports, 4 British Transports and assorted air and naval support they may or may not have from winning.
Germany will only have to leave more defensive power in W. Europe to stop America from taking it. However, why would you want to do that??? It’s West Europe, not Berlin or South Europe, so no real lose to Germany if it falls to America, especially considering the force that wins will be very minimal at best.
Meanwhile, you have almost assuredly destroyed enemy fighters and decimated both countries’ armies that attacked you, for a portion of your own army. Oh sure, you’re size will be much smaller, but then again, BOTH of their sizes will be as well!
So, assuming a normal game, you have the following:
W. Europe defends with 20 infantry, 7 armor, 1 fighter, AA Gun
England attacks with 12 Infantry, 2 Artillery, 2 Armor, 2 Fighters, Bomber, Battleship
Germany wins with 10 Infantry, 7 Armor, Fighter, AA Gun remaining
America attacks this with 8 Infantry, 3 Artillery, 5 Armor, 3 Fighters, Bomber, Battleship using all 8 of their transports from the 4 by 4 system they had
America wins with 1 armor, 2 fighters and a bomber.
Germany, has now pulled apart the transport system, it will take TWO turns to get that system up again plus England has depleted it’s Karelian stack to weaken the Germans enough to allow America the chance (67% chance) to win in W. Europe. Germany’s out no land because 1 armor is not going to protect W. Europe for squat against a determined German, however, now there’s nothing left to attack it but British forces. Germany should be in more then good enough position to defend against 6 transports of British guys, especially now that England has no air force left.
So what has the extra transports gotten the allies?
Germany down 105 IPC in Ground and Air Forces
England down 89 IPC in Ground and Air Forces
America down 66 IPC in Ground and Air Forces (not counting the tank that lives to defend another day)
And, America is completely out of the game for two full game turns while they set up the transport system again.
105 IPC for 155 IPC and a stronger strategic position on the board all because I didn’t waste my resources on extra transports and didn’t set myself up to win at all costs over a piece of land I could allow the allies to take for a solitary turn and reclaim before I needed to collect my taxes that year? Sounds like an awesome deal to me!
