[1] Police captain Domenico Avitabile was the first Italian commandant of the concentration camp, succeeded by Mario Taglialatela.

It now fell under the jurisdiction of the German Commander in Chief of the Security Police, Wilhelm Harster, who was based in Verona, while the Campo Vecchio remained under Italian control.

SS-Untersturmführer Karl Friedrich Titho was appointed as commander of the German part of the camp, with SS-Hauptscharführer Hans Haage as his deputy, while the guards consisted of 40 Italians, later reinforced by five Ukrainians.

It was during this period that the first two trains left on 19 and 22 February 1944, intended for Anglo-Libyan prisoners heading to Bergen-Belsen and Auschwitz, with the camp still under Italian control.

[1] During Titho's time as camp commander at Fossoli di Carpi, 67 prisoners were executed in the Cibeno massacre as a reprisal for a partisan attack on German soldiers at Genoa.

On 12 July 1944 70 prisoners were selected on the pretext of being taken to Germany and their names read out by Titho, moved on trucks to a local shooting range and 67 of them executed, while three managed to escape.
