Operation Kopaonik began on 11 October 1942 when the 1st battalion advanced toward Chetnik forces in Kriva Reka from
Kosovska Mitrovica, the 2nd battalion advanced from
Raška and parts of the 3rd battalion advanced from
Novi Pazar. On 12 October 1942 the Axis troops completely encircled the village of
Kriva Reka. They stormed into this village as they were informed that the headquarters of
Rasina Corps of Keserović and Chetniks under his command were in the village. Keserović was informed about the attack of Axis forces and successfully retreated units of his detachment. Himmler was pleased with the Prince Eugen Division and visited it for three days as soon as Operation Kopaonik ended. After the operation was finished, on 18 October Himmler arrived to Kraljevo and celebrated birthday of
Prince Eugene of Savoy together with members of SS Division that bore his name. In his order issued for this operation on 5 October 1942, the commander of Axis forces in this operation, Arthur Phleps, ordered to his units to consider entire population of the region as rebel sympathizers. When Axis forces failed to capture and destroy Chetniks in Kriva Reka, they punished the village and burned all houses in the village. The Axis troops captured civilians who lived in the village and took them to the village church and blow it up. There were 46 men, women and children who were killed in the destroyed church. The number of murdered civilians in Kriva Reka was more than 300. The total number of civilians murdered during this operation is 690. During the second half of October 1942 Prinz Eugen Division attacked Mihailovićs Chetniks in
Gornji Milanovac and
Čačak. At that time, General Mihailović was with his Supreme Command in
Montenegro, which was under Italian occupation. From the beginning of 1943, General Mihailović prepared his units for the supports of Allied landing on the
Adriatic coast. General Mihailović hoped that the Western Alliance would open the Second Front in the Balkans. == Aftermath and legacy ==
