hi,
ANY landings in france in 1943 are doomed...
germany was just way to strong to be defeated in 1943 in this way
the things about "shermans superior to german tanks", well, in 1943 the shermans that fought german tanks had vastly superior numbers, the shermans are not equal to german MarkIV... cause the markIV kill the sherman at any range but the sherman do not the same with the markIV... the StugIIIG is superior to the sherman, too.
only the numbers make the difference.
in 1943 the allies do not have air superiority in this areas...
in southern france they are NOT in italy - a sideshow for the germans, but in the most important area next to northern france/lowlands... so no chance...
the germans have the better troops (in quality - green american troops are just cannon fodder - esp. if we take the armored divisions, they are no real enemy). more planes (achiving air superiority in this area, if needed) and better logistics.
the allies have worse planes (compared to 1944), less ships with worse flak (again, compared to 1944), and less supply/troops
also, the germans subs are still a possible danger to the allies (again this is total different in 1944)
italy NOT being invaded is no enemy to germany... why should it be... italy only surrendered to the allies because they invaded. they exactly waited untill enough troops had been on italian soil to surrender...
with the clusterfuck in southern france the wallies cannot invade in italy, they loose to much troops and equipment to do.
