Ignacy Paderewski traveled around the United States in his capacity as a Polish dignitary during World War I to rally support for Poland's cause. He was a well loved pianist having toured the United States extensively in his previous visits. Throughout 1916 and 1917, he encouraged Polish Americans to volunteer to fight in Europe.
Some 24,000 Polish Americans were equipped by the French and fought under the command of General Haller. Due to the French uniforms, they were known as the Blue Army.
This collection includes a number of postcards from a mass in the field and a presentation of arms. There are also papers of Jozef Olsztynski who was a volunteer and they include his mobilization and discharge papers.
