The members of the 101st Airborne are in training at Camp Toccoa, Georgia. After finishing their training, the men ship out to Uppottery, England. They practice their jumps, do field exercises, and find out that their first combat experience will be Normandy.
The members of the 101st Airborne drop into Normandy on D-Day. The drops are a huge failure, and the members of Easy Company are separated. Winters finds some members of his company and leads them to an American camp. He is then put in charge of the company when it becomes obvious that their commander did not survive the jump. Easy Company is then sent to take out a German artillery position that is giving the troops on Utah Beach some problems.
After finally regrouping in Angoville-au-Plain, Easy Company is sent to take the town of Carentan, which is essential so that the United States can bring its tanks off the beaches. After struggling to take the city, the men of Easy Company along with several others are forced to prepare for the imminent German counterattack.
A group of replacement paratroopers join Easy Company just before the company is set to jump into Holland for Operation Market Garden. When Easy gets to Eindhoven, they meet no resistance, instead meeting locals who are happy to see them. But when they are patrolling a nearby town, they are ambushed and "Bull" is left behind.
Winters led a daring mission at a Dutch dike and is promoted to Battalion. Winters does not like being stuck behind a desk and is concerned about the leadership of the three companies he is now in charge of. News reaches of a massive German attack in the Ardennes Forest and Easy Company is sent to defend the Allied lines, while short on supplies and ammunition, and without winter gear.
Easy Company is in the forest just outside of Bastogne, Belgium. The company fights off frostbite, hunger and the occasional German attack. Medic Eugene Roe meets a Belgian nurse who he becomes friends with while trying to keep the men of Easy Company alive.
Lt. Dike has been put in charge of Easy Company, but he is a terrible leader. He is constantly leaving the frontline and going off to random places whenever he is needed. The soldiers begin to wonder if he will be able to lead them when they are told they will have to take the nearby town of Foy.
Easy is in a town called Haguenau, near the German border. Winters is ordered to send a group of men across the river on a nighttime raid to take German prisoners.
Easy finally gets into Germany and is met with little resistance. While on a patrol, the members of Easy discover and abandonned concentration camp. The German guards have left, but all the prisoners are still in the camp.
Easy enters Berchtesgaden, to capture the "Eagle's Nest", a mountain mansion that was built by the Nazi party for Hitler. After going to the mansion and taking many of Hitler's belongings, the men are given some down time. With Hitler having commited suicide the war in Europe is over. The men of Easy celebrate, but soon they are told that all of the members without enough points to go home will be sent Japan.
