By 1918 Christy Mathewson was two years removed from his final pitch in the big leagues and was serving as manager of the Cincinnati Reds when late in the season he enlisted in the United States Army for World War I. As the players he managed reeled off a six-game winning streak to conclude the 1918 season Mathewson was stationed in Washington DC. Just a few days after the conclusion of the season the future Hall of Fame hurler would receive his orders that he would be deployed to France as part of the Chemical Warfare Service Gas and Flame Division. It was in this capacity that Mathewson was exposed to poison gas during an unfortunate training accident; the lung damaged hastened his demise as he died from tuberculosis in 1925. Presented here are five original documents related directly to Mathewson's deployment: 1) Confidential Orders from the War Department: Dated September 6 1918 ordering Mathewson to proceed to Hoboken NJ and report to the Commanding General at the Port of Embarkation to be transported to France. 2) Western Union Telegram from acting general P.C. Harris communicating the orders ostensibly to Mathewson's commanding officer in Washington DF dated September 6 1918. 3) Confidential Orders from the American Expeditionary Forces related to Mathewson's travel to Blois France dated September 23 1918. 4) Christy Mathewson's Transfer of Property form dated September 26 1918 detailing the military equipment being given to Captain Mathewson (consisting primarily of the standard model 1910 military pack haversack meat can untensils helmet etc) signed by Ernest Levy and marked as received. The area where Mathewson should have signed is crossed off. 5) Special Military Travel Orders dated February 1 1919 advising (among other things) that "Capt. Christopher Mathewson C.W.S. whose services are no longer required in the A.E.F. will proceed to Headquarters Base Station No. 5 reporting upon arrival to the Commanding General for return to the United States." Each piece is printed on either extremely lightweight paper or onion skin with a variety of small tears paper loss wrinkles and folds consistent with their age and being folded and stored in a pocket - in some cases in the possession of Mathewson himself as he traveled throughout France in late 1918. What appears to have been less than five months stationed in France was ultimately life-changing for Mathewson; his tragic accident surely shortened his life and resulted in his passing from tuberculosis j
