In the later stages of World War I, over twenty thousand Polish soldiers mustered in the US to form a Polish brigade. It was a delicate situation, as the Allies needed the soldiers but the Poles were committed to the creation of an independent Poland at a time when their country was ruled by Russia, an ally of the US. In the event, policy differences with the US government prompted the Poles to move over the border to Niagara-on-the-Lake, where they established a base camp. Paid and equipped by France, the Poles were trained by Canadian officers and then shipped off in batches to fight on the Western front, thereby deferring their attempts to create an independent Poland. At the end of the war, with the Tsar gone and the Bolsheviks in control of Russia, the Polish brigade – or “Blue Army” as it was called, from the colour of their uniform – crossed Germany to return to their homeland, where they played a key role in the foundation of an independent Poland. The graves of the 25 Polish soldiers in Niagara-on-the-Lake recall these historical complexities, and a small shrine has been erected in their honour.
