This book is the only one in French that recounts the history of the 3rd Infantry Division of the United States Army, from its creation to the present day. This large active unit is also known as the "Marne Division" because of its exploits in 1918. Between the two world wars, it remained in the order of battle despite the Great Depression of 1929.

After the United States entered the war in 1941, the 3rd Division was among the first to be engaged against the Axis powers in North Africa, and distinguished itself on every battlefield: Sicily and then Italy, the Allied landings in Provence, the Vosges-Alsace campaign during the winter of 1944-1945, and until the surrender of Nazi Germany. The history of this division is linked to the books already published by Sophia Histoire & Collections on the 36th and 45th American divisions.
