	According to post-war Yugoslav sources, the Partisan Rasina detachment and the Chetniks' commander Keserovic agreed to attack Kruševac together, on 23 September 1941. On 24 September, Keserović's Chetnik detachment attacked German troops in the Kruševac district, killing 23 soldiers. The fighting between attacking rebels and the Axis garrison had lasted for four days when Kosta Pećanac personally, with a large force of his Black Chetniks, came to release the Axis garrison. The post-war Yugoslav sources blamed Keserović for the failure of the attack on Kruševac. These sources accuse Kesrović of attacking German garrison earlier than agreed and of halting the attack when Partisan communist forces joined the attack. At the end of September, Chetniks and Partisans published a printed flyer against Kosta Pećanac and signed it "People's Liberation Movement of Chetniks and Partisans" ().
