Through various hundreds of “clichés d’époque”, the journey of this American division that landed in Provence in August 1944 after a long campaign in Italy, leads us just to the heart of Germany, where this military unit is the first to enter the concentration camps of Dachau. This American division had formerly freed a part of Southern France, and then went back up the valley of the Rhone up to the Vosges. As its squads are made up of numerous native american soldiers, the 45th division has achieved copious honours during the three hard battles which could be compared to the battle of Normandy that took over the spotlight the following years.
