Many were terribly sick during D-Day, for sure. The army issued sea-sickness pills before the attack. Still the ride was so terrible many threw up during the crossing, and were already very weak before they got out on the beach. Saving Private Ryan had this kind of scenes iirc. And reportedly yet many more suffered side-effects and got killed because they had trouble staying awake.
