designed to annihilate the guerrillas in place or drive them into strong Italian blocking forces to be brought up to the Italian side of the demarcation line. Planned for mid-January 1942, the operation would have the advantage of cold weather, inconvenient for the Germans but disastrous for the guerrillas, who lacked proper clothing and equipment for operations in the snow. Also, the 342d Division would be available, just prior to its departure for Russia.
Well planned and typical of antiguerrilla measures of the period, the operation was conducted from 15 to 26 January, with the 342d and 718th Infantry Divisions, as well as Croatian national forces, participating. guerrillas were estimated at 4,000, concentrated about Sarajevo and Visegrad and the area to the north. Meeting strong resistance, the Germans suffered a total of 25 dead, 131 wounded, and almost 300 cases of frostbite, against 521 guerrilla dead and 1,331 captured. Booty included 855 rifles, 22 machine guns, 4 field pieces, 600 head of livestock, and 33 draft animals. A tactical success, the operation failed to achieve its purpose when the Italian forces against which the guerrillas were to be driven did not arrive in time to prevent the escape of large numbers of the guerrillas into the Italian zone of interest in Croatia.
Reports from German commanders who had participated indicated that the Croatian troops could perform satisfactorily only when integrated with German units, and that the Croat officers and noncommissioned officers lacked training and tactical ability. The escape of entire guerrilla units also made obvious the need for a combined command, with authority over all German, Italian, Croatian, and other forces participating. On one occasion, during the operation, Italian airmen bombed a German-held village, whereupon the Germans requested Italian air support be withdrawn. Another mistake was the assignment of Ustascha troops to areas populated mainly by Serbs. Finally, the understrength German divisions (two regiments of infantry rather than the normal three) in the "700 series" in the southeast lacked personnel and staying power for sustained operations against strong guerrilla forces.
Sharp fighting at Valjevo in February caused the Germans almost 500 casualties, as against over 3,500 guerrillas killed in action or shot in reprisal. Lacking troops, it was obvious that General Kuntze would require the assistance of the Italians and Croatians if his meager forces in Croatia were to quell the disorders in the German zone of interest.
A trip to Hitler's headquarters and to Italy was instrumental in securing approval for a combined German-Italian-Croatian operation to clear east Bosnia. General Bader, now commanding all German forces and the administrative area in Serbia, was named task force commander, under operational control of the Italian Second Army for
