did the slow start of DDay help it out

I was a show on Agent Garbo, Juan Pujols, who helped convince Hitler that there would be a second invasion. I thought that the fact that the invasion was behind schedule also helped convince Hitler that a second invasion was coming and so he cancelled Rommel's orders to send the 2 SS PZ divisions to Normandy

 

That is Operation Fortitude you are talking about. Its aim was to deceive OKW and OB-West that Normandy landings were a deceptin and real landings would be done to Pas de Calais by fictional 1st US Army Group.

 

You mean 2 Panzer Division.
They were in reserve in the Somme area.

2 SS Panzer Division were miles & miles away on 6th June.
Took them weeks to get to Normandy.

well, anyway, it took Hitler a month to release the 15th Army from Calais. Some parts were released earlier but that seems to me Hitler expected the other invasion until early July. And I am sure his staff tried to convince him this was the real deal in Normandy.

 

You could probably make the argument that delay enabled the Allies enough time to secure beachhead.

 

The invasion itself was really just a decoy to get German attention away from the eastern front. It really didn't matter what happened in Normandy, Bagration was what was important. The western allies could have kept their casualties much lower if they actually trusted the USSR. But I think they finally started to smell the reek of Stalin and what post war Europe was going to be like.

 

I think the French, Dutch, Belgians, and former West Germans at least are glad that Normandy wasn't a failure...

In that sense, it mattered a lot.

 

I get what your saying, but I disagree. Yes, Churchhill, Stalin, and most of the fighting alliances in Europe were clamoring for the Western front to be established, but I don't buy that it was just a diversionary tactic. That's a grand fighting force to be thrown at the beaches and dropped behind enemy lines to just expect "to keep the Germans busy."

 

The invasions of Sicily and mainland Italy were large invasions in regards to troops and materiel, and the reinforcements that poured in after. Since it was a new front of battle established in mainland Western Europe and Germany had to bring large amounts of troops in, why wasn't Stalin satisfied with the Italian front? It was technically a second front.
