[1][2] In August 1941, following orders from the Chetnik Supreme Command of Draža Mihailović, Boško Todorović and Veselin Misita gathered men to go to Bosnia because the Chetniks had been ordered to avoid fighting the occupying Axis forces in German occupied territory of Serbia, but to fight against the fascist Ustaše in the Independent State of Croatia, of which Bosnia was a part.
[3] The historian Marko Attila Hoare states that Todorović and Jezdimir Dangić arrived in eastern Bosnia in mid-August 1941 on the orders of Mihailović, to take over control of the revolt on his behalf.
[8] A slightly different account is given by the historian Branko Latas, who states that on 2 September 1941, Todorović crossed the Drina river and went into eastern Bosnia together with several officers.
[12] On 16 November, Chetnik and Partisan representatives met at Vlasenica in an attempt to resolve tensions that had arisen due to the outbreak of fighting between the two forces in the neighbouring German-occupied territory of Serbia.
During the conference, Todorović worked to avoid a break between the two forces, while other Chetnik leaders like Dangić wanted to bring the conflict to a head.
The members of the commission were the commander of the Romanija Partisan Detachment, Slaviša Vajner-Čiča, the Chetnik leader Pero Đukanović, and Todorović, who was supposedly considered to be neutral.
The draft declaration tried to maintain unity between the Bosnian Serb rebels of both movements, but was rejected by both the commander of the Partisan General Staff for Bosnia-Hercegovina, Svetozar Vukmanović Tempo and Dangić.
The following day, the Chetniks issued their own declaration, banning all political activity in liberated territories and proscribing the arming of Muslims and Croats.
Dangić's Mountain Staff was turned into the Chetnik-run "Provisional Administration of East Bosnia", with Todorović appointed chief of the operational department.
[15] For example, after the handover of Goražde on 29 November, several hundred civilians were massacred, and after the Italians turned Foča over to the Chetniks, around 500 Muslims were killed.
[18] At the beginning of December 1941 Todorović requested support of Durmitor Partisan detachment to fight against Muslim units that committed numerous massacres of Serbs.
[27] On 11 January 1942, a preliminary collaboration agreement between a representative of the eastern Bosnian Chetniks and the Italian VI Corps was concluded.
[32] On 19 January 1942, the Partisan Provincial Committee and General Staff for Bosnia-Herzegovina issued a proclamation denouncing Todorović and other Chetnik leaders for turning the uprising into a Serb-chauvinist campaign against Muslims.
[35] In eastern Herzegovina the class struggle began between Chetniks and Partisans, with Todorović being among the first victims of this dramatic conflict which erupted between former allies who fought together against the Axis forces until then.
[41] In his memoirs, published in 1985, Vukmanović Tempo accused his fellow Partisan leader Rodoljub Čolaković of friendly treatment of Boško Todorović.
