The 115th Infantry Division initially fought on the Western Front in World War I, entering the line in the Artois in April 1915, fighting in the Second Battle of Artois, and then moving to the Aisne region. On July 30, the division left the line and was transported to the Eastern Front, arriving in August and entering the line in the siege of Kovno. It participated in the Gorlice-Tarnów Offensive and was in the line until November 1916, when it went to the Romanian Front. It fought on the Romanian front into late 1917, and then remained in Romania for several months after the armistice on that front. In April 1918, the division was transported back to the Western Front. After a period in reserve and on the Belgian/Dutch border, it entered combat in June 1916 in the Champagne region. It remained in the Champagne, Verdun and Woëvre regions and then fought against the Meuse-Argonne Offensive. Allied intelligence rated the division as third class.
