Map of the site where the Battle of Vauquois took place. The extensive tunnel system in the area is depicted. This battle took place during World War I from 1914-1918. The small village of Vauquois, France, was strategically located on a hill that gave a commanding view of the surrounding area. Control of the hill was contested throughout the entirety of the war. This conflict led to one of the most extensive tunneling operations during the war. The American unit that fought at Vauquois during the Meuse-Argonne Offensive was the 35th National Guard Unit, made up of solders from Missouri, Kansas, and Illinois. The 36th and 90th National Guard Units, from Texas, were also involved in the offensive. There is no text on the map. The topography is marked in meters.
