Shore Bombardment Effectiveness?

[MartinL]

Hi
After a visit to the Normandy beaches last year one thing that suprised me was the the vast scale of the operation i think from pegasus bridge in the east to Utah beach in the west i drove about 60 miles.
The only visable bombardment damage was at colville battery (2nd and 3 rd photo are a naval shell ,was told at time ship name but fogott) the first photo shows even the biggest bunkers are no match to an raf 10,000 lb tallboy)


I have lots of photos of of very large bunkers howsing german 6 " guns completelly broken by bombing and was suprised to find very little evidence of naval bombardment. 1 reason for this might be that the batteries were a mile or so inland so wowld only be visable from the grownd so need spotting hence the arial attack, were the nature of the turain of coast which would be spotabble, so shellable from sea is verry sandy , some places the sand penetrates 1/2 km inland, so the shelling evidense would disapere quickly ???
