Haller's Army (Błękitna Armia, the Blue Army) was a Polish military force formed in France during WWI (1917-1919) that fought for Polish independence, and whose members are presumed to have been Polish citizens.
In depth
Haller's Army (Błękitna Armia, the Blue Army) was a Polish military force formed in France during World War I (1917-1919) under the command of General Józef Haller. It fought on the Western Front and later in the Polish-Soviet War (1919-1921).
Many members of Haller's Army were Polish emigrants from the United States and Canada — approximately 20,000-38,000 Polish-Americans volunteered. Their service records are held at the Polish Army Museum in Warsaw and the Pilsudski Institute in New York.
For CBD cases, service in Haller's Army is strong evidence that the ancestor was a Polish citizen (or considered himself one), which helps establish the citizenship chain — particularly for ancestors whose pre-1918 citizenship status is ambiguous due to the Partitions.
