The route proceeded by rail through Neunburg vorm Wald, Weiden in der Oberpfalz, Pfreimd, Nabburg, and Schwarzenfeld, where, on 19 or 20 April, about 750 of the Jewish prisoners were stranded after another aerial attack disabled the locomotive. The SS murdered any prisoners who were unable to continue the march on foot. After the liberation, 140 corpses were found in a nearby field; some of the victims had been killed in the air raid, while others had been murdered. One prisoner testified that "The SS men joked and laughed during the shooting... the prisoners were led in groups of 15–20, they had to lie on the ground and were shot in the nape". The survivors were divided into columns 100-strong and marched through heavy rain and mud. Many were ill with fever, but anyone unable to keep up was shot on the spot. At Neukirchen-Balbini, the death march joined up with the larger one of non-Jewish prisoners. Another group of Jewish evacuees continued towards Theresienstadt, arriving in early May.
