Only around 2% of the British Army was involved in the invasion.

Weather or something similar causing the invasion to fail is possible, though unlikely - far more possible is it preventing it at all.

There was significant concern over this - it caused it to be delayed at least once. There was only a minuscule window for it every month, when the tides were right. Anytime past early fall, and the weather in the Atlantic changing likely would have put it off until the next spring.

If the invasion had failed, they simply would have either done it again, or moved the troops to Italy. More likely, they just invade southern France as per otl, with a minor invasion in the north later on.

For the Germans, the likely result of a failed invasion in the west would be them pulling troops from the area eastward, to slow down the Soviets.... making invasion in the west easier. The German offensives against the Allies will be used in similar moves against the Soviets instead. Bet on them having a bit more success in what was their last offensives in that region otl, and the war lasting longer.

Probably means a slowing of moves against Japan, as there would be a slight shortage of landing craft for a temporary period.

Bet on about the same amount of land being under Soviet control, maybe a bit less.
