During the last two world wars, war prisoners were allowed, under certain conditions, to write to their families, but these letters were censured. The censors may have had the posibility to make their own postmarks and a few illustrated them with stags, trees, armorials, haidresser´s instruments etc.
Of course we don´t know the reasons why they chose such or such motif and one must be cautions in interpreting their meaning. We know of a postmark representing a beehive and three others showing a bee.
Worldwar I (1914-1918)
Osnabrück camp: a camp for
commisioned officers. Two kinds of pre-printed envelopes wearing the
same consorship postmark showing a little red beehive.
Radstadt camp: Reserve Lazarett 4 - the postmark shows a bee inside a green triangle.
Worldwar II (1939-1945)
OFLAG XI/A (Osterrode): this camp was opened on 28.08.1939 and closed on 04.04.1944 to be transfered to Wladinir Wolynsk in Ukrain where it became the disciplinarian OFLAG no. 365.
STALAG VI/F - all censorship marks are illustrated (1 to 13). No. 9 shows a bee.
