10% Slovene, 5% Montenegrin, 2.5% Macedonian and 2.5% Bosnian Muslim. Italians were also in the army: more than 40,000 Italian fighters were in several military formations such as 9th Corps (Yugoslav Partisans), Partisan Battalion Pino Budicin, Partisan Division "Garibaldi" and Division Italia (Yugoslavia) later and others. Following the Soviet-Bulgarian offensive in Serbia and North Macedonia in the autumn of 1944, mass Partisan conscription of Serbs, Macedonians and eventually Kosovo Albanians increased. The number of Serbian Partisan brigades went up from 28 in June 1944 to 60 by the end of the year. In regional terms, the Partisan movement was therefore disproportionately west Yugoslav, particularly from Croatia, while until the autumn of 1944, Serbia's contribution was disproportionately small. During 1941 until September 1943 from Croatia and Bosnia and Herzegovina 1,064 of Jews joined the Partisans, and largest part of Jews joined the Partisans after the capitulation of Italy in 1943. At the end of the war 2,339 of Jewish Partisans from Croatia and Bosnia and Herzegovina survived while 804 were killed. Most of the Jews who joined the Yugoslav Partisans were from Croatia and Bosnia and Herzegovina and according to Romano this number is 4,572 while them 1,318 were killed. According to the Encyclopedia of the Holocaust of the United States Holocaust Memorial Museum, In partitioned Yugoslavia, partisan resistance developed among the Slovenes in German-annexed Slovenia, engaging mostly in small-scale sabotage. In Serbia, a cetnik resistance organization developed under a former Yugoslav Army Colonel, Draža Mihailovic. After a disastrous defeat in an uprising in June 1941, this organization tended to withdraw from confrontation with the Axis occupying forces. The communist-dominated Partisan organization under the leadership of Josef Tito was a multi-ethnic resistance force – including Serbs, Croats, Montenegrins, Bosniaks, Jews, and Slovenes. Based primarily in Bosnia and northwestern Serbia, Tito's Partisans fought the Germans and Italians most consistently and played a major role in driving the German forces out of Yugoslavia in 1945. By April 1945, there were some 800,000 soldiers in the Partisan army. Composition by region (ethnicity is not taken into account) from late 1941 to late 1944 was as follows: According to Fabijan Trgo in the summer of 1944 the National Liberation Army had about 350,000 soldiers in 39 divisions, which were grouped into 12 Corps. In September 1944 about 100,000 soldiers in 17 divisions were ready to enter the final phase of the battle for the liberation
