Imaigine if D-day/Operation Overlord failed, that the germans managed to repel the invesion of Normandy.
What would the allies do them? Would the prepare a new operation, and where would it be? Or would the allies decide to push up from Italy? And how much time it would take them to preform the operation? Because preparing Operation Overlord took a lot of time, supplies were transported from the US to UK, and the u-boats failed ot stop them the first time but maybe they would have intercepted the convoys the next time. Though the allies were already aware how to defend from the "wolf pack", and much or less by 1944 the battle of the Atlantic was already at its end and it was going bad for the german u-boats.
Most importantly if the allies did not landed on Normandy if the attack was repeled from the germans would that affect the Eastern Front, the Soviet advance toward Germany?

the russians would have pushed on irregardless of weather overlord failed or not, stalin would no doubt be pissed as he was eager for a new front to open so as to divert german manpower to the west. russians would have had a harder time but probably still break their way through to berlin. americans and british would have continued pushing through italy and may have instead swiced to using it as the way into germany instead.

it is very hard to say if weather the allies would have launched another attack on northen europe since if overlord failed then the losses would have been catastrophic in the number of men and materials lost

Since a new invasion would have taken a long time, the war would have ground on slowly, Russians closing in from the east and the US continuing fron Italy, preparing for a new Normandy. The trump card would have been a year later, however, when the US got The Bomb. The first few would have been used in Germany rather than Japan. That would have been the end game.

ah thats true, by the time they would have been ready for a new invasion the A-bomb would have been ready and would have then used that.

Tend to agree with Skiz's fair assessment too; in any case, with or without A-bomb, the III Reich was already doomed; its fall may have required a little more time (probably some months); nothing more that that.

Their only trump card at that point was their excellent jet fighter, the ME 262, but allied bombing of oil facilities had rendered the jets fuel-less and the Germans were towing the few that flew from hanger to airstrip with ox teams.

Yeah, I think they would have switched their resources to Italy.
They possibly may have tried again eventually in the south of France I think.

The A Bomb would have been used on the Germans first, not Japanese. Allies probably would have tried to keep pushing up through Italy. Germany was going to lose either way, I guess the only difference would be which countries are communist and which countries aren't at the end of the war. It's hard to tell whether or not it would have effected the advance of the USSR because either Hitler could have had troops tied up in France repelling the invasion which could speed up the Soviets, or Hitler could feel more secure about his western side and focus on the east and the allies in Italy if he assumes the allies won't invade again, which is also hard to say. A very big amount of questions with this one.

Anything that made the US and Britain get into Germany later would have given the Soviets more momentum, which would have been bad for Europe after the war. At the time of D Day and the invasion, there was sentiment (both on the American side and the German side) that the US should team up with German remnants to turn eastward and stop the USSR, but Eisenhower resisted that.

The allies would never choose the momment in "gambler" way, as Hitler did. Is obvious they were prepared for a ventual repulse, and had a B plan. The proper invasion force was only the peak of the iceberg. The logistic system(platforms, fleet, british harbours, reserves in men and materials...) beyound the beaches represented more than 80% of the efforts. in the best case, germans would been able to reject the first wave of invasion-they couldn't been able to affect logistic system. So, with an intact logistic system, and enough reserves, probably allies would continued few weeks with heavy bombardment of the french shores, which would transformed the land into a bunch of ramble bariers, germans free. Then, a new invasion would followed.
