In June 1941 Račić arrived on mountain Cer near Šabac where he designated the place for the headquarters of Yugoslav Army soldiers under his command. During the Summer of 1941 he organized several military units under his command, first the Cer company commanded by the Leutenant Ratko Teodosijević who came from Ravna Gora together with Račić. Then he established the Čokešina company, the Mačva company, the Machine gun company commanded by Leutenant Voja Tufegdžić. The newly established Prnjavor company was composed of Serb refugees who escaped from Croatian Ustaše genocide and was a unit within Chetnik Cer Detachment. The Chetnik detachment was military unit of the operational Royal Yugoslav Army and the commanding officers were active and reserve Yugoslav officers determined to struggle against the enemy using guerilla Chetnik methods. Two Chetnik detachments participated in the Capture of Banja Koviljača conducted 1–6 September 1941: the Jadar Detachment and the Cer Detachment under command of Račić. The commander of the operation was Nikola Radovanović, a lieutenant general. They were quickly transported from Prnjavor through Loznica and Trbušnica to Mount Gučevo above Banja Koviljača where Račić, commander of the Cer detachment, was informed of the intention of the Jadar Detachment of 3,000 men to attack Banja Koviljača. On 21 September 1941 the Cer Chetnik Detachment commanded by Račić conducted attacks on Šabac. Račić was commander of all forces attacking Šabac, the Chetniks, the Partisans and detachment of Pećanac Chetniks commanded by Budimir Cerski. Even after the first conflicts between Partisans and Chetniks began in September 1941, Račić was praised by official communist organ "Borba" as one of the "good" Chetniks who struggled against the occupying forces alongside communist forces. On 4 October 1941 there was the first "peaceful contact" between rebels in Serbia and German ocupying forces when Captain Račić sent a letter to commander of the 10th Company of the 699 German Infantry Regiment in Šabac.
Communist invasion of Serbia
On 7 May Račić and other officers from HQ of Cer Corps participated on the meeting with representatives of Nedić regime and officers of Serbian State Guard in Monastery Radovašnica to discuss how to protect Serbia from Communist terror. Račić emphasized that the main task of his unit is to protect Serbia from communists. Račić proposed that Germans should provide his unit with 100 machine guns and 1,000 guns, but this proposal was futile because Germans did not provided him with requested arms, and situation on the field remained as it was. In 1944 when strong communist Partisan forces invaded Serbia from Bosnia, Račić was appointed as commander of all operations of the Yugoslav Army in the Fatherland in Serbia. The group of Chetnik Corps under his command and group of Corps under command of Dragutin Keserović accepted the main blow of communist attack during the Battle for Serbia. On 23 July 1944 the communist controlled forces attacked Nova Varoš and captured it. This was the signal for Tito to order urgent movement of Partisan Operational groups of Divisions into Serbia with main goal to destroy military forces and political organization of nationalists. The main blow of communist controlled forces across Kopaonik was received only by Chetnik units.
Failed attempt to gain German support for unification of all anti-communist forces in Serbia
When Račić realized that Chetniks will not be able to resist communist forces, he proposed to Draža Mihailović on 10 August to approach to negotiate with Germans. When Mihailović approved his proposal, Račić organized a meeting with German representatives headed by Rittmeister Von Vrede in Topola on 11 August. Račić proposed the Germans to organize unified anti-communist front of Serb national forces composed of Chetniks, Serbian State Guard and Ljotićevci, insisting that Chetniks will not wear German uniforms and Mihailović remain illegal. The meeting did not have any results because the German representatives were not authorized to make important decisions. Probably on 15 August 1944 Mihailović met General Milan Nedić on the meeting organized on initiative and insisting of Račić, although Mihailović reluctantly agreed to attend it. The meeting was organized late at night in village Ražana and no written records exist from this meeting. In his later testimonies Nedić stated that he explained Mihailović that Germans will soon leave Serbia and that strong communist forces will occupy Serbia, so he proposes to unite all national forces to defend it. Mihailović agreed with Nedić and explained that he have enough men to defend Serbia but not enough arms and ammunition. Nedić promised to try to get support from Germans and approached to Hermann Neubacher who supported the idea but failed to gain Hitlers approval for it, because Hitler insisted that his support to Serbia could endanger Croatia.
Retreat to Bosnia
On 21 October 1941 in Ivanjica Račić organized a conference of all commanders of the Chetnik Corps and Grops of Corps to decide about their further actions. They decided to join the Chetnik command in Bosnia based on the unrealistic hope that Allies will invade Adriatic coast. Račić was killed in Autumn 1945 near Krupanj as an outlaw.
Legacy
In 1998 potporučnik of the Yugoslav Army in the Fatherland Dušan Trbojević who was officer in Cer Corps commanded by Račić published his memoires about this military unit and Račić during World War II:
