If D-Day had been postponed in June and again in July, what was the plan?

I watched the TV movie about Eisenhower starring Tom Sellick. They needed a full moon, calm weather and low tide. Moon and tide coincided once per month and weather was of course unpredictable. Severe storms had moved in on June 5 but they got a brief break in the weather landed on June 6.

In the movie they are discussing that if they dont go in June, the next window is July and if July is missed there may not be enough time to gain a foothold before winter. (I guess assuming an August invasion). Also the longer they had this huge army waiting around the more of a chance of the Germans figuring out their plans.

If there had been no break in the weather on June 6, and lets say its horrible weather again in July, what were the plans? Wait till 1945? A last ditch launch in August under bad conditions? It was also a morale issue with hundreds of thousands of soldiers confined to barracks waiting to go. They couldn't have stretched that out another year. What was Plan B?

 

Moved to the "what if" section

 

What ifs galore these last two weeks.

 

In 1944 the Germans were still losing the war. They were being driven out of Russia and the Allies had a strong foothold in Italy. There are numerous factors to consider, but regardless, the Third Reich was still going to crumble. This would have taken longer, but with the development of the Atom Bomb and the determined push by the Soviet Army, who knows.

The downside, as there would have been many, was that without the two fronts, the Germans would have pulled divisions in waiting along the Atlantic Wall and other regions and resupplied the Eastern Front to slow the advance of the Soviets. Although Germany's end was near, this would have called for a complete reallocation of allied troops and material and an alternative calculation of invasion. This would have taken time. The Soviets would have borne the brunt of this failure, but by sheer numbers would have continued their push, although slowly, into German occupied territory. The war would have dragged on.

I still believe that the Allies would have landed in southern France even without the invasion, this would have diverted some Axis troops, but not anywhere near what Normandy attracted. In addition, the first nuclear test, Trinity, took place on July 16. This may have been an option as well. Without the secured beachhead in Normandy, I believe the bomb may have been a foregone conclusion. The bomb may have been Part B.

I'm interested into what paths this thread will take.

 

Operation Bagration would still have destroyed Army Group Center, and there was never any coming back from that, even if they'd stripped the West free.

An estimated 400.000 casualties (Killed, Wounded, Missing, and Captured).

 

Ah the concept of "deep battle." Heard much of the term when researching. Do you think the concept could have been used with as much success with other nations? Not a huge military strategist but I feel enormity of forces is a prerequisite.
