In 1943 Endre Bajcsy-Zsilinszky advised the Regent to appoint János Kiss to Defence Minister, but Horthy chose Lajos Csatay instead. Lt. Gen. Kiss was the member of the Military Tribunal organized to investigate the Újvidék massacre. After the occupation of Hungary by Nazi German forces he gave a military plan to Horthy, in which he urged the Hungarian Army to join forces with the National Liberation Army of Tito.
