During the chaotic multi-front conflicts of 1919 following World War I and the Russian Revolution, the newly formed Ukrainian People's Army faced simultaneous pressure from Bolshevik forces, White Guard armies, and Polish troops, with the Kingdom of Romania also hostile. This left Ukrainian national forces with no secure territory or allies on which to rely.
The Ukrainian People's Army found itself encircled in an area south of Kyiv, trapped between Bolshevik, White Guard, and Polish forces. The situation became known as the Ukrainian Death Triangle, or Quadrangle of Death when Romania's hostility is included, reflecting the near-total military isolation of Ukrainian national forces throughout 1919.
During the winter of 1919–1920, approximately 25,000 Ukrainian soldiers died of typhus while hemmed in on multiple sides. Many others were subsequently captured by Polish forces, effectively ending organized Ukrainian military resistance and contributing to the eventual collapse of the Ukrainian People's Republic as an independent state.
