(IV. gorski zdrug)
by H.L. deZeng IV

Formed April 1942 in Slavonski Brod from men called up in August/September 1941 and trained by the Germans in Austria. Operated during 1942 and the first half of 1943 in a strength of four 1,000-man battalions under the lst Mountain Division, and then reorganized and expanded during the summer of 1943 beginning 15 July in Sisak (later changed to Daruvar) as an independent brigade under Croatian II Corps. The reorganized Brigade HQ was the former 1st Mountain Division headquarters and staff, and to this were added two mountain infantry regiments (the 4th and the 8th), artillery groups plus other assets. Although the German 187. Res.Div. was assigned overall responsibility for the reorganization, a German army training staff and battalion (Deutsches Ausbildungs-Btl. 4 bei der 4. kroatischen Gebirgs-Brigade) was assigned to improve the brigade’s effectiveness and reliability. Reorganized on 21 November 1944 as part of the completed reorganizing of the Croatian armed forces. The regiments were done away with and the Brigade once again consisten of four battalions (I – IV) plus the I Artillery Gp. and a signal company. On 1 December 1944 the Brigade was incorporated into the new 7th Croatian Mountain Division, where it remained until the end of the war. (1)
