The total number of Croatian Army soldiers killed in the period from the beginning of July 1991 until the end of March 1992 was 487. The number of severely wounded was 1,160, and 1,141 soldiers were slightly wounded. The ratio of the killed to wounded was 1:5, except in the municipality of Osijek, where it was 1:2.5. The number of casualties increased continually and culminated during November 1991, the period of fiercest fighting in this territory, followed by a gradual decrease. The most common mechanism of injury was explosives, which were responsible for almost half of all casualties (47.9%). An equal number of soldiers were killed by explosives and infantry weapons (46.4% and 44.9%, respectively). Casualties caused by motor vehicle crashes are not to be ignored, especially after the cease-fire agreement. Car crashes frequently resulted in death (from 4.5%-12.4%).
