Yes. Eisenhower was a logistics guy. D-Day was a triumph of logistics. The Allies built up enough resources to force a win before attempting the invasion. They were willing to wait because of the failures of Dunkirk and Dieppe. Those operations didn't have enough resources behind them.

We're under fire! Yeah - under fire!! Those five thousand ships the Allies couldn't possibly have, as you say - they've got 'em! Yeah, they've got 'em!! - Major Werner Pluskat, June 6, 1944.
