a postcard system of communication to the uk (via the red cross) and the channel islands (via german “feldpost” addressed to the “kanal inseln”) started in october 1942. internees were allowed three lettersheets and four postcards a month. lettersheets could contain as many words as could be fit on the page, very different to ordinary pow's. each main camp had its censors, with wurzach using biberach censors. laufen produced printed christmas postcards with a drawing of the outside of the schloss (1943) and in the vaulted canteen (1944). trunks of clothing and goods, left in the islands arrived in the camps, fairly intact. individual parcels up to 5 kg in weight could be sent to camps post free, however tobacco in them tended to vanish. the red cross also supplied some clothing.
