Germany collects 30 IPCs + 9 IPCs for France + 19 IPCs for pillaging Paris + 1 IPC for Bulgaria + 2 IPCs for Finland + 5 IPCs for not being at war with USSR + 5 IPCs for holding Denmark and Norway, for a total of 71 IPCs.
UK1
UK at this point can either vacate Scotland, or try to defend it. Either way, this sealion will still work. If UK defends Scotland, it will be less units defending London in turn 3.
Optimal thing for UK to do to defend London is to build 9 inf, and move all units in Scotland to London and move the fighter from Gibraltar to London.
Also, since Sealion is obvious, the UK player might move the fighter from Malta to Gibraltar and the tac bomber from sz 98 to Gibraltar, to defend London in G3. Italy can do something about this.
I1
Italy builds whatever
Key point: Italy should still have 1 tra and 1 cru in sz 95, which can be used to bombard and attack the 2 UK planes in Gibraltar (if UK landed them there in UK1), leaving a little less defence for London. Italy might just have a tra left in sz 97 to help out, especially if UK didn’t use the Malta fighter and sz 98 tac bomber to attack the ships in sz 97.
G2
Buy 9 tra (63 IPCs) and 1 destroyer (8 IPCs).
Attack Scotland with battleship, cruiser and 2 tac bombers to land on AC along with a transport 3 inf and 3 tanks from Berlin. If UK player has 3 fighters in Scotland and scrambles them, UK will probably lose them vs 2 tac bombers, 1 AC, 1 battleship and 1 cruiser. If UK does lose them, it will make taking over London way easier on round 3. Lose the tac bombers first in the sea battle if there is a scramble.
But let’s say the UK player left Scotland open, so Ger takes it with 3 inf and 3 tanks.
Important!
Germany does a strategic bombing raid of London! Use the 2 bombers and 3-4 fighters in Belgium. If UK uses some of its fighters as interceptors, it might lose 1, which would be good for less defense of London. Don’t forget, all the antiaircraft guns in London don’t count on a strategic bombing raid of the factory! They only defend the combat units! Thus 2 bombers and say 2 fighters should survive, with London being bombed for an average of 9 IPCs (die roll +2, according to 2nd ed. rules).
Non-combat a couple of planes to Western Germany to protect (via scramble) the new German naval units, which will be placed in sz 113.
Non-combat any remaining tanks in France to Western Germany. Move 1 art from Normandy to Belgium.
UK2
UK, having collected 28 IPCs + 1 IPC saved + 5 IPCs for having all of its European territories, minus 9 IPCs to repair the factory, should have 25 IPCs to spend, the wise purchase being 8 inf.
Thus London will be being defended by 1 bomber, 9 + 8 + 4 = 21 inf, 1 mech inf, 2 French inf, 4 UK fighters and 1 French fighter.
G3
Germany builds all inf to defend against USSR, who can attack in round 4.
Charge! Ger attacks London with 3 inf, 3 tanks from Scotland, and 5 tanks, 4 art and 9 inf from Berlin and 1 art and 1 inf from Western Germany using 9 tra from sz 113 and 1 tra from off Scotland. Ger also attacks London with 3 inf from Western Germany and 1 art from Belgium, with the remaining 2 tra from off Scotland. Ger also attacks with 6 planes, 1 of them being a bomber (if all 5 antiaircraft from the UK are in London then chances are 1 bomber will survive) Also bombard with battleship and cruiser.
So
UK has 1 bomber with a defence of 1
UK has 24 units at 2 for a defence of 48
5 units at 4 for a defence of 20
UK has a total defence of 69
Ger has 10 inf at 1 for an attack of 10
12 units at 2 for an attack of 24
8 tanks at 3 for an attack of 24
1 bomber at 4 for an attack of 4
Ger has a total attack of 62
According to my calculations, Germany should win the battle with 1 tank.
If you use “low-luck” (as I think it’s called), this is a guaranteed win.
On G4 Germany can build all tanks with the loot from London and go after Russia while blocking the US from taking back London with what’s left of the navy.
