Oflag IV-A was a World War II German POW camp for officers located in the 15th-century Burg Hohnstein, in Hohnstein, Saxony.

[1] As a Schutzhaftlager ("protective custody camp"),[2] it held political prisoners, mostly members of the Communist Party, who were forced to work in a nearby quarry.

[1] The camp was reopened on 1 October 1939 to house Polish generals and their staffs captured during the German September 1939 offensive.

By September 1940 the prisoners at the camp were mainly French, with 100 officers up the rank of colonel, and 28 generals.

[3] By the end of October 1940 all these prisoners had been transferred to other camps, and the castle was then used to accommodate evacuee children from Hamburg and Berlin.
