The camp was opened in October 1939 as Oflag IX-A to house POWs from the British Royal Air Force and the French Armée de l'Air. The camp was renamed Oflag IX-A/H (Hauptlager, "Main camp") in June 1940, after Oflag IX-C at Rotenburg an der Fulda became a sub-camp (Zweiglager) designated Oflag IX-A/Z.
The camp was closed in February 1941, but reopened in July when it was used for housing RAF and British Army officers. On 3 September 1941 three RAF officers, Dominic Bruce, Peter Tunstall and Eustace Newborn, escaped disguised as members of a "Swiss Commission". They were escorted to the main gate by another prisoner, John Milner, dressed in a German officer's uniform that had been found in an apparently forgotten set of attic rooms. They passed through the gate and then, wearing faked Luftwaffe uniforms, headed to an airfield near Kassel intending to steal a Ju 52, which Newborn had flown before the war, and fly home. Unfortunately, there were no suitable aircraft, so they decided to head to France and contact an escape line. After ten days, they arrived at Frankenberg, but were challenged by soldiers suspicious of their uniforms. Speaking little German, they were soon identified as escapees and arrested. Returned to Spangenberg, the three were each sentenced to fifty-three days in solitary.
The Germans marched the prisoners east on March 29 1945. The Americans liberated the camp's inmates at Lengefeld unterm Stein on 4 April. Spangenberg Castle was destroyed by American bombs after Oflag IX A/H had left.
