The Battle of Jadotville, also known as the Siege of Jadotville, occurred in September 1961 in the town of Jadotville (now Likasi) in the Katanga Province of the newly independent Republic of the Congo. This conflict involved Irish UN peacekeepers and Katangese forces during a period of political turmoil and secessionist movements in the Congo.

The Irish troops involved were part of the United Nations Operation in the Congo (ONUC). A company of Irish peacekeepers, designated as 'A' Company of the 35th Battalion, was stationed in Jadotville. The Katangese secessionist forces, led by Moise Tshombe, besieged the Irish contingent.

Despite being heavily outnumbered and lacking air and artillery support, the Irish soldiers held their ground for six days, from September 13 to September 19, 1961. They eventually ran out of water, food, and ammunition, leading to their surrender. The Irish soldiers were subsequently taken as prisoners of war by the Katangese forces.

The Battle of Jadotville has become a significant part of Irish military history. In recent years, there has been increased recognition and public awareness of the bravery and professionalism displayed by the Irish soldiers during the siege. The soldiers involved in the battle faced challenging circumstances and were later commended for their resilience in the face of overwhelming odds.

The event was depicted in the 2016 film "The Siege of Jadotville," which aimed to bring attention to the story and the courage of the Irish peacekeepers during this conflict.
