This is belated. Today is the anniversary of D Day plus one. From the noted military historian SLA Marshall published 16 years after the invasion:
Able Company has planned to wade ashore in three files from each boat, center file going first, then flank files peeling off to right and left. The first men out try to do it but are ripped apart before they can make five yards. Even the lightly wounded die by drowning, doomed by the waterlogging of their overloaded packs. From Boat No. 1, all hands jump off in water over their heads. Most of them are carried down. Ten or so survivors get around the boat and clutch at its sides in an attempt to stay afloat. The same thing happens to the section in Boat No. 4. Half of its people are lost to the fire or tide before anyone gets ashore. All order has vanished from Able Company before it has fired a shot.
