In 1956, in the crucible of the Suez Crisis, L.B. Pearson invented United Nations peacekeeping. The Canadian foreign minister did not do so alone, and peacekeeping as it evolved was not exactly what he had in mind.
In 1993, during the civil war in the former Yugoslavia, Canadian peacekeepers with the United Nations (UN) advanced into disputed territory in Croatia with orders to implement the Medak Pocket ceasefire agreement between the Croatian Army and Serbian irregular forces. Soldiers of the 2nd Battalion, Princess Patricia’s Canadian Light Infantry (2 PPCLI), came under Croatian attack for more than 15 hours. In the firefight that ensued – the most significant combat experienced by Canadians since the Korean War – 2 PPCLI held its ground and preserved the UN protected zone. UN Secretary-General Boutros Boutros-Ghali said the Canadian soldiers brought credit to their profession, saved lives, and enhanced the credibility of UN peacekeeping forces.
