On June 6, 1944, D-Day, planes with thousands of paratroopers cross the English Channel to France, where they come under heavy fire. None of the men land where they expected to, and many lose their weapons and supplies in the drop. Winters links up with solitary soldiers, and they set off to find their units. Winters is later chosen to lead an attack on a fortified German artillery position; the mission is successful, but Winters, now acting company commander, loses his first man.
