 In June 1943 it was placed under the administrative control of Stalag VIII-B Lamsdorf and was renamed Stalag IV-B/Z.In November 1943 there was another reorganization, Lamsdorf was renamed "Stalag 344", and a large number of prisoners were transferred to Teschen, which became Stalag VIII-B.Because of these organizational and number changes there is considerable confusion in accounts of prisoners, even in official German records.
