Blue Army (Poland)
The so-called Blue Army (Polish: Błękitna Armia; French: Armée bleue), or Haller's Army, officially Armia Polska we Francji („Polish army in France“), was a Polish military contingent created in France during the latter stages of World War I. The name came from the French-issued blue military uniforms worn by the soldiers. The symbolic term used to describe the troops was subsequently adopted by General Józef Haller von Hallenburg to represent all newly organized Polish Legions fighting in western Europe.
