Milestones of Loss

250 dead

Around 250 UN peacekeepers of many nationalities died during ONUC — among them Secretary-General Dag Hammarskjöld, killed in the still-unexplained Ndola air crash.

40,000 dead

The 1964 Simba rebellion and its suppression were the bloodiest phase of the crisis, with tens of thousands killed in rebel massacres and government-mercenary reprisals.

100,000 dead

No reliable overall death toll exists; estimates for the whole crisis range widely, and the figures here are broad approximations across five years of scattered conflict.

All figures are historical estimates and vary across sources. The true human cost of war is impossible to fully quantify — these numbers represent the best scholarly consensus. Each number was a person with a name, a family, and a life unlived.
