The paper presents and analyzes the war events in the area of Mostar in the period from 1992 to 1994. At the beginning of the paper, I explain the social and political situation in Yugoslavia and Mostar before the war, in order to get a broader picture of the events that followed. The conflicts between the HVO and the JNA / VRS in Mostar are then described. Special emphasis is placed on Operation Seagull (Čagalj) and the consequences of the 1992 war. After that I gave an overview of the causes of the conflict between former Croat and Muslim allies. The conflict in Mostar between the HVO and the ABiH began in the spring of 1993, resulting in the division of the city into two parts. At that time the struggle for control of the Vranica building was of great importance. Following the attack at the end of June and in Operation Neretva 93, the ABiH wanted to bring the whole of Mostar under its control, but Croatian forces prevented this. The conflict with many victims continued until 1994, when a truce was signed between Croats and Muslims.
