This website contains the history of the 267th Field Artillery Battalion, which was attached to the Third Army and served in the European Theater of Operation during World War II.  Formed in March 1943, the Battalion landed in Normandy 1 September 1944 and served in four campaigns.  Armed with 240mm howitzers, its men fired the largest mobile gun in the U.S. Army's arsenal during the Campaign for Northern France.  It was one of only fifteen 240mm howitzer battalions.  With the Battle of the Bulge, the 267th was reassigned from artillery to the Third Army's Provost Marshall, where its troops engaged in prisoner handling and guarding areas as assigned.  

The Battalion was ordered to the Pacific to participate in the invasion of Japan, but that order was cancelled with the end of the War in September 1945.  The 267th returned to the U.S. on 11 February 1946 and was inactivated the following day at Camp Kilmer NJ.  It was authorized four battle streamers including: Northern France, Rhineland, Ardennes-Alsace and Central Europe.  In the European Theater of Operation the Battalion had two men wounded and none killed.  Three officers received the Air Medal.  Four officers and forty-eight enlisted men received Bronze Star Medals, and two enlisted men received Purple Heart Medals.  

In March 1955, the Battalion was reactivated as the 267th Armored Field Artillery Battalion  and armed with 155mm self-propelled Howitzers.  It deployed to Babenhausen Germany on 1 April 1956 and was inactivated on 1 December 1957 in Germany.
