In turn, the Chetniks maintained control over the countryside and kept it free of Partisans, drawing on Italian stocks for arms and ammunition.
This general rising cost the Montenegrins dearly—15,000 dead and wounded and an additional 10,000 of the sparse mountain population shipped off to forced labor. The arrangement with the Chetniks also set the pattern for the Italian occupation—troops seldom moved out of the garrison towns, and then only along the main roads and in strength, accompanied by armored vehicles and often under air cover.
One other major countermeasure by the Italian occupation forces against the irregulars was undertaken in July of 1942 when Generale di Corpo D'Armata (Lieutenant General) Mario Robotti launched a drive against the Partisans in Slovenia. Committing 7 army divisions, 2 Blackshirt battalions, and Slovene auxiliaries, General Robotti managed to surround the enemy. Several thousand casualties were inflicted on the Partisans, and the survivors were routed. The Partisan movement in Slovenia in this operation suffered a setback from which it did not recover for months.
Guerrilla activities against the Germans in Yugoslavia commenced shortly after the cessation of formal hostilities. However, in the beginning, open resistance to the German forces was on a smaller scale than in the Italian-occupied areas, and the guerrillas conducted themselves more cautiously. With the departure, by late June 1941, of the bulk of the combat troops for Operation BARBAROSSA, the WB Southeast reported an increasing number of sabotage incidents. Road and railroad bridges were blown; telephone and telegraph lines were cut; trains derailed; German military vehicles, traveling either alone or in convoy, fired on or destroyed; and isolated detachments guarding industrial and military installations attacked. During July and August there were also daily attacks on Serbian police posts to obtain weapons and on villages to obtain food. Standing crops were burned, banks robbed, and a general state of uncertainty and unrest created.
A number of small-scale operations by the 704th, 714th, 717th, and 718th Infantry Divisions, dispersed over Serbia and the German zone of interest in Croatia, resulted in a large number of casualties and arrests, but accomplished little in effectively curbing the guerrilla movement. Nor did the shooting of hostages or burning of homes of suspects and whole communities suspected of sheltering the guerrillas achieve the desired results. By 5 September the WB Southeast realized that the situation could not be mastered with the forces at hand and ordered the 125th Infantry Regiment (Separate) from the Salonika area to Belgrade.
It was now obvious that a strong, well-organized, and adequately armed revolt was underway in northwestern Serbia, and that the
