Operation Jackal (Serbo-Croatian: Operacija Čagalj, also known as Operation June Dawns (Operacija Lipanjske zore), was an offensive of the Bosnian War fought between a combined Croatian Army (HV) and Croatian Defence Council (HVO) army against the Army of Republika Srpska (VRS) from 7–26 June 1992. The offensive was a Croatian pre-emptive strike against the VRS, a Bosnian Serb military formed in May 1992 from Yugoslav People's Army (JNA) units that were stationed in Bosnia and Herzegovina. The HV concluded that the JNA offensive operations of April and May 1992, resulting in the capture of Kupres and much of the Neretva River valley south of Mostar, were aimed at capturing or threatening the Croatian Port of Ploče and possibly Split. To counter this threat, the Croatian leadership deployed the HV, under the command of General Janko Bobetko, to the "Southern Front" including the area in which Operation Jackal was to be conducted.
The offensive marked the first significant Bosnian Serb defeat in the war and placed the HV in a favourable position to push back the VRS and remnants of the JNA holding positions north and east of Dubrovnik. The HV later re-established overland links with the city which had been under siege by the JNA since late 1991. The attack resulted in an HV/HVO victory and the capture of approximately 1,800 square kilometres (690 square miles) of territory in and around Mostar and Stolac.
