In Mar 1943, as the Axis troops and their collaborators pushed partisan forces from Bihać in North-west Bosnia to Herzegovina in the south, Mihailović left his HQ to take direct command, and spent the next few weeks in
Kalinovik, Konjic and
Foča. On 6 Apr 1943, Bailey reported that chetniks were openly collaborating with the Italians in Foča area and that Mihailović had refused all access to the British mission. Around the same time, the Axis defeat at Stalingrad and North Africa, made the collaboration with resistance groups in the Balkans more important. British PM
Winston Churchill had obtained ten
Halifax bombers to add to the four
Liberators and ease the delivery of military aid and in Apr 1943 sub-missions with Mihailović's commanders throughout Serbia were established. On 27 May 1943,
Operation Typical, the first dedicated mission to partisans' HQ was dropped at the height of a large German offensive
Operation Schwarz which aimed to destroy them. Both missions by now had American (
OSS) representatives, Bailey's had Capt Mansfield, and Deakin's had Lieut M.O. Benson. Over the next few months, the situation remained complex. Mihailović continued to collaborate with the Italians and remained focused on fighting the partisans. His troops refrained from attacking the Axis for fear of reprisals and he was still unhappy about the lack of British aid. Partisans, on the other hand, continued to fight Germans, Italians, Ustashe, Chetniks and others, while professing their commitment to the Soviet cause. The British government then decided to back both sides with equal support, sending a senior officer to each HQ, Brigadier
Charles Armstrong to Mihailović and
Brig Fitzroy Maclean to Tito. The two brigadiers arrived at the time of
Italian surrender and saw the two armies' behaviour in its aftermath. At
Berane, place of
Venezia Division's HQ, its commander General Oxilia agreed with Mihailović's representative and Bailey to come over to Allies' cause together with his troops and arms. Tito's 2nd Proletarian Division, led by
Peko Dapčević, arrived shortly afterwards and persuaded Oxilia to join the partisan side instead. This was seen as a great loss of reputation, arms and territory by Mihailović. Armstrong was present on 5 Oct 1943 when Mihailović's troops overtook the German garrison in
Višegrad allowing Maj Archie Jack to blow up a large railway bridge nearby. Together with blowing up of four railway bridges at
Mokra Gora this was the first significant and overt anti-German action by Mihailović's troops since the beginning of the war, although in Bosnia rather than Serbia as originally planned. BBC broadcast attributed successes of Mokra Gora and Višegrad raids to partisans, further angering Mihailović, who returned to his previous priorities of fighting partisans and ignoring the occupiers and the British Liaison Officers (BLOs). On 8 Nov 1943, the British Foreign Minister
Anthony Eden met King Peter II and the new Yugoslav PM
Purić and told them that the British intended to ask Mihailović to carry out certain specific military operations and that a failure to accede to this request would stop British aid. The task was to destroy railway bridges in the
Ibar and
Morava valleys. Mihailović had agreed, but the request was withdrawn at the last moment. At the same time Churchill had access to intercepted highly secretive German messages and thus knew that the partisans continually resisted and fought. On 10 Dec 1943, he declared that he wanted Mihailović removed by the end of the year. Two months later, on 25 Feb 1944, he sent a message to Tito informing him that the British missions were being withdrawn from Mihailović. == The withdrawal ==
