Because of low morale among army conscripts and their increasing disaffection with the Ustaša regime as the war progressed, the Partisans came to regard them as a key element in their supply line. According to William Deakin, who led one of the British missions to the Partisan commander-in-chief Josip Broz Tito, in some areas, Partisans would release army soldiers after disarming them, so they could come back into the field with replacement weapons, which would again be seized. Other army soldiers either defected or actively channelled supplies to the Partisans—particularly after the NDH ceded Dalmatia to Italy. Army troop numbers dwindled from 130,000 in early 1943 to 70,000 by late 1944, at which point the NDH government amalgamated the army with the Ustaše army and was organised into eighteen divisions, including artillery and armoured units. Despite these difficulties, the army, along with the German-commanded XV Cossack Corps, was able to assist the Wehrmacht to hold its lines in Syrmia, Slavonia and Bosnia against the combined Soviet, Bulgarian and Partisan offensives from late 1944 to shortly before the NDH collapse in May 1945.
