I’ve saved your link for further reading...it’s hard to read the difficulties these men faced....it’s written that 40% of the loss of our guys came in the first 30 minutes....and I can believe that...the Germans gave it all immediately, just as they determined to do as they believed whatever happened there would likely determine their end or not.
At Omaha beach none of the German strongpoints had been taken out by the pre-invasion bombardment. The bombers had dropped their loads farther inland and the naval guns hadn’t found them either. For the first few hours Omaha beach was a shooting gallery. Everything that landed was piling up near the shore. The sea literally turned red at the shoreline.
Around 9 am our destroyers came up within a thousand yards of the shore, trained their guns on the bluffs and blasted them for half an hour.
