Planes against France are not needed.
As Germany if you do not get rid of the 3 UK FTR’s in UK on turn 1, then there will be no Sea Lion.
With your attack, Uk will have 3 FTR’s, 2 INF, plus 50/50 1 INF and 1 ARM from Quebec, plus 9 INF it builds in UK=12INF, 3FTR’s defending Sea Lion…possibly add an extra INF and ARM. Assuming you built 2 TRS with Germany…giving you 3 total you can have: 3INF, 3ARM, BB, probably 5 aircraft(minus 1 from your SZ110 attack, and minus one from AA when you make the attack on UK.
Round 1:
UK: 12INF at 2, 3FTR’s at 4(lets say no TRS from Quebec)…should be 6 hits vs Germany(3INF, 2ARM, 1FTR).
vs
Germany: 3INF at 1, 3ARM at 3, 1BB at 4(once), 1 Bomber, 2 TAC’s, 2 FTR’s…should be about 6 hits(just short, but I’ll give it to you(UK loses 6 INF).
Round2:
UK: 6INF at 2, 3 FTR’s at 4…should be 4 hits(all German air gone if you want to take UK).
vs
Germany: 1ARM at 3, 1Bomber at 4, 1TAC at 4, 1 TAC at 3, 1FTR at 3…should be about 3 hits(UK loses 3 INF)
Round3:
UK: 3INF at 2, 3 FTR’s at 4…should be 3 hits(Last German unit gone, Sea Lion fails)
vs
Germany 1ARM at 3…maybe UK loses 1INF.
Sea Lion fails, and thats without your 50/50 attack on the DD/TRS off of Quebec. Not good.
