Rare letter on official stationery from a prisoner at the Sachsenhausen-Oranienburg Nazi concentration camp. This letter is from Bohumil Nypl, born on November 5, 1887, prisoner number 40782, Block 48. Nypl was an educator and a resistance fighter who arrested by the Gestapo on September 3, 1940. He was imprisoned in Jihlava, Wroclaw, then the Oranienburg and Bergen-Belsen concentration camps. Nypl died during the camp evacuation in March 1945. On November 21, 1943, Nypl wrote to his family (in part): ‘…On the 17th, came the package that was sent on the 13th…everything is in the best condition. Thank you very much!… Your sister should have given her child a playmate a long time ago, now it is already too late…My sister is paying for wealth with her health…And we? We are both becoming thick in spite of the reciprocal longing that is exhausting us and is draining our strength. Peculiar. At the time undesired weight loss cure turned into the opposite in our case…’. Mailing folds. The envelope bears the official stamp of the camp.
