Kościuszko fought for American and Polish independence.
So he is hero for both nations.
West Point was first occupied by the Continental Army on 27 Jan 1778, making it the longest continually occupied post in the United States. Between 1778-1780, Polish engineer and military hero Tadeusz Kościuszko oversaw the construction of the garrison defenses. The high ground and a narrow "S" curve in the Hudson River enabled the Continental Army to prevent British ships from sailing up river and dividing the Colonies. The Great Chain was strung across the Hudson River in order to obstruct British ships from attempting to navigate the river
Prior to leading the 1794 Uprising, he had fought in the American Revolutionary War as a Colonel in the Continental Army. In 1783, in recognition of his dedicated service, he had been brevetted by the Continental Congress to the rank of Brigadier General, and that same year he had become a naturalized citizen of the United States.
He led the Kościuszko Uprising (1794) against Imperial Russia.
