Combat chronicle

The Lehr Infantry Regiment joined the Guards Fusilier Regiment in the new 6th Guards Infantry Brigade as part of the 3rd Guards Division in the Guards Reserve Corps.^[4] It remained with the 3rd Guards Division throughout the war, even after the Division was triangularized in May 1915.^[5]

The Guards Reserve Corps was assigned to the 2nd Army as part of the right wing of the forces that invaded France and Belgium as part of the Schlieffen Plan offensive in August 1914. It participated in the capture of Namur and was immediately transferred to the Eastern Front to join the 8th Army in time to participate in the First Battle of the Masurian Lakes. It then fought in the Battle of Łódź. It continued fighting in the Carpathians and Galicia and then participated in the Gorlice-Tarnów Offensive.

The Regiment returned to the Western Front with its Division in April 1916 and entered the trenches in the Champagne region. In July 1916 it fought in the Battle of the Somme. At the beginning of September 1916, the division was again sent to the Eastern Front, returning in November. In 1917 it participated in the Battle of Arras and the Battle of Passchendaele. It then fought against the Allied tank attack in November 1917 in the Battle of Cambrai. In 1918, it fought in the German spring offensive. During the subsequent Allied offensives and counteroffensives, the division faced the French and Americans at Aisne-Marne and in the Meuse-Argonne Offensive.^[6] The division was rated as one of the best German divisions by Allied intelligence.^[7]

By the end of the war, the Regiment was still with the 3rd Guards Division, XXV Reserve Corps, 3rd Army, Heeresgruppe^[f] Deutscher Kronprinz on the Western Front.^[8]
