Infanterie-Regiment 66 fought in most of the great battles on the western front: Mons, Le Cateau, the Marne, Arras, the Somme, the French offensive on the Chemin des Dames, the Kaiserschlacht in March 1918, the German offensive on the Chemin des Dames, the Second Marne, and the Siegfried Line. It continually demonstrated the highest levels of tactical skill.

This is an exceptional text written by a soldier and academic, Dr. Otto Korfes, who served as an officer in the regiment and then became an historian in the Reichsarchiv, the repository of the German Army's Great War documents. Korfes consulted the regimental war diaries and after action reports, as well as making extensive use of first-hand accounts. The book includes 23 tactical sketches and dozens of pencil drawings by the great German war artist, Döbrich-Streglitz.
