When the United States entered World War I in 1917, it sent the American Expeditionary Force to relieve the worn and beleaguered Allied Forces. On September 20, 1917, Congress approved the creation of the Second Division of the American Expeditionary Force. A hybrid Marine/Army unit, it was conceived and ultimately formed overseas, primarily from units in France. Giving themselves the nickname "Second to None," the Second Division effectively stopped the German drive on Paris in June 1918, becoming the first American unit to fight the enemy in a major engagement and revitalizing the Allied war effort.

This volume details the fighting experiences of the Second Division, from its creation in the fall of 1917 through 1919. The book follows the unit from training in Toulon through the major campaigns including Chateau Thierry, Soissons, Blanc Mont and Meuse Argonne and records the experiences of the men who served. Appendices provide information regarding the pedigree of the division and its units; a syllabi of the Second Division's experiences; and a list of major awards received by Second Division personnel. Detailed maps and period photographs are also included.
