of Yugoslavia, and established the Serbian National Bank to replace it. From the outset, the Aćimović government lacked any semblance of power. It was effectively a low-grade and basic instrument of the German military occupation regime, which performed administrative duties within the occupied territory on behalf of the Germans. The three main tasks of the Aćimović administration were to secure the acquiescence of the population to the German occupation, help restore services, and "identify and remove undesirables from public services". This included Jews, Roma and "unreliable" Serbs. The Commissioner Government was capable of handling routine administrative tasks and maintaining law and order in a peacetime situation only, and was closely controlled by Turner and Neuhausen. Neuhausen was effectively an economic dictator, and had complete control over the economy of the occupied territory and finances of the puppet administration, to one end – maximising the contribution they made to the German war effort. This was demonstrated in the fixing of wages and prices; officially the responsibility of Letica's finance department, they were actually set by Neuhausen's staff. Also in May, Förster ordered the Aćimović administration to investigate the causes of the invasion. The inquiry concluded that the Yugoslav government had "recklessly brushed off the peaceful intentions of the Third Reich and provoked the war". One of the first tasks of the administration involved carrying out Turner's orders for the registration of all Jews and Romani people in the occupied territory and implementation of severe restrictions on their activities. These were aimed at bringing the occupied territory into line with the rest of Nazi-occupied Europe, and included the wearing of yellow armbands, the introduction of forced labour and curfews, and restricted access to food. Turner explicitly stated that "[t]he Serbian Authorities [ie the Commissioner Government] are responsible for the implementation of all measures contained in the order". By this means, the Commissioner Government took part, albeit under German orders, in the "registration, marking, pauperisation, and social exclusion of the Jewish community". Aćimović's Interior Ministry included a section dedicated to implementing anti-Jewish and anti-Roma laws, but the primary means for the carrying out of such tasks was the 3,000-strong Serbian gendarmerie, which was based on elements of the former Yugoslav gendarmerie units remaining in the territory, the and regiments. It had been formed on 17 April on Förster's orders, and its acting head was Colonel Jovan Trišić. The gendarmerie was also responsible for
