What had become a sanctuary for thousands of frightened civilians fleeing violence in West Nile turned into a scene of bloodshed that continues to haunt survivors and their descendants more than four decades later.
The massacre occurred during a turbulent period following the fall of President Idi Amin in 1979 and the return of Milton Obote to power after the disputed 1980 elections.
West Nile, Amin's home region, became a focal point of suspicion as government forces battled remnants of Amin's former army. Amid growing insecurity, thousands of civilians sought refuge at Ombaci, believing that the Catholic mission, school grounds and the presence of the International Committee of the Red Cross would offer protection from the conflict.
Instead, on the morning of June 24, soldiers of the Uganda National Liberation Army surrounded the compound and accused those sheltering there of collaborating with rebels.
Witness accounts describe a prolonged assault as troops moved through classrooms, workshops, church buildings and storage rooms where families had gathered. Men, women and children were killed by gunfire, grenades, bayonets and beatings, while widespread looting accompanied the violence.
Although the exact number of victims remains disputed, historical records indicate that close to 100 people were killed during the attack.
A mass grave within the school grounds contains the remains of 97 victims, standing as a stark reminder of the day's events. Hundreds more were injured, while many survivors carried deep physical and psychological scars long after the violence ended.
For years, the Ombaci massacre received little national attention, remaining a painful memory largely preserved within families and communities across West Nile.
In recent years, however, survivors and local leaders have pushed for greater recognition of the tragedy. Annual memorial prayers are now held at Ombaci every June 24, while advocacy groups continue to call for official acknowledgement, reparations and support for those affected.
