Oy Vey.
June 5 was scrubbed due to bad weather. The next available window after June 6 due to tides etc was too far away.
You would have had to go if the sea conditions were right, but the weather prevented flying. Otherwise Op-Sec would have been compromised.
Bad weather = ducks walking on both sides of the ditch.
Now we have a ground pounders war with 0 air support for either side, but a stinking HUGE artillery platform off shore.
Doable, but with major casualties above what was experienced, which was still under the high commands estimates.
Get the Paras loaded ASAP, send them in as infantry via boat with support weapons, now you have a formidable force for defence or offensive manouvering.
Prioritise AT off the beaches, chuck your pre load plan out the window and adapt to the situation within 24 hours with a shift of focus. Use heavy bombers who will hopefully be able to fly through the weather, to saturate targets inland with better visability, marshalling points, known barracks, stores, railways etc to isolate the area.
The whole of Europe can't be socked in the whole time.
Move, Adapt, Win. The breakfast of champions.
