The World War I Montsec American Monument is located on the isolated hill of Montsec (Thiaucourt), France. This majestic monument, commemorating the achievements of the American soldiers who fought in this region in 1917 and 1918, dominates the landscape for miles around. It commemorates reduction of the St. Mihiel Salient by the U.S. First Army, September 12-16, 1918, and operations of the U.S. Second Army, November 9-11. It also honors combat services of other U.S. divisions in this region and in Alsace and Lorraine. Names of nearby villages liberated by American troops are carved upon the outside frieze.
