Château-Thierry, FRANCE - WWI Battle Ruins:  Château-Thierry is a French commune situated in the department of the Aisne, in the administrative region of Hauts-de-France and in the historic Province of Champagne.  Aisne is named after the river Aisne.  The Battle of Château-Thierry was fought on 31 May 1918 and was one of the first actions of the American Expeditionary Forces (AEF) under General John J. Pershing. It was a battle in World War I as part of the Second Battle of the Marne, initially prompted by a German Spring Offensive. German and local actions at Château-Thierry recommenced on 31 May to 22 July 1918, against the AEF, an American Expeditionary Force, consisting of troops from both the United States Army and Marine Corps units. These units were the newest troops on the front in France and just barely out of training.  The AEF counter-offensive combat action at Château-Thierry was relatively brief starting on 18 July 1918 and lasting for less than a week and was part of the allied effort to push back the recent German advance. American forces had linked up with their French allies at the Marne River on 3 June 1918 and had forced the Germans back across the river. This set the stage for the action at Château-Thierry and at the Battle of Belleau Wood. However, the later action raged for another three weeks.  This Divided Back Era (1907-15) postcard is in good condition, but shows some soiling.
