Hi All, I am in the process of typing up my Grandfather's POW diary. Thought this might help as there is not too much info on the various work groups off the main camps. I have put in brackets possible current Polish place names, or corrections as the diary is hard to read in places. XXI.B Schubin (Szubin) XXI.B.H.21 Janowitz (Janowice) XXI.B.H Thure (Tur) XXI.B.H.35 Dobrezelin (Dobrzelin) XXI.A Schildburg (Ostrzeszów) XXI.CZ Crates (Gratz) XX.B Wilenburg XX.B.256 Kalwe XX.B Marianburg XX.B.354 Backerburg XX.B Marianburg XX.B.5.3 Deatch Eyleau (Ilawa) XX.B Wilenburg XX.B.995 Marianburg XX.B.873 Elbin(g) (Elblag) II.E Schwerin Hope this helps! Any differences or additions, will be happy to include.
