Thaddeus Kosciuszko was one of the first European volunteers to aid the American revolutionary cause in 1776. A brilliant Polish military engineer, Kosciuszko designed and constructed fortifications to help defeat the British, most notably at Saratoga and West Point in New York. Kosciuszko returned to Poland and led his own countrymen in a failed attempt to free them from foreign oppression. Seriously wounded in battle and imprisoned in Czarist Russia, upon his release, he returned to the United States. In a small rented room on the second floor of this house, Kosciuszko spent the winter of 1797-98 reading, sketching and receiving distinguished visitors like Vice-President Thomas Jefferson. The Memorial is located in Philadelphia.

Valley Forge National Historical Park commemorates more than the collective sacrifices and dedication of the Revolutionary War generation, it pays homage to the ability of everyday Americans to pull together and overcome adversity during extraordinary times.

The hardships of the encampment claimed the lives of one in ten, nearly all from disease. Despite the privations suffered by the army at Valley Forge, Washington and his generals built a unified professional military organization that ultimately enabled the Continental Army to triumph over the British.

The lower Delaware River region contains immense resource diversity, combining an area of high population density with a wealth of natural, cultural, and historical resources and recreational opportunities. The river valley houses cliffs rising 400 feet above the rivers that provide for magnificent scenery and habitat unique to the region. The south-facing, desert-like slopes are home to the prickly pear cactus, while the north-facing slopes display flora and fauna usually only found in arctic-apline climates. The river itself provides habitat for American shad, striped bass, and river herring and is an important component of the Atlantic Flyway, one of four major waterfowl routes in North America. From a historic veiwpoint, the river is one of the most significant corridors in the nation, containing buildings used during Washington's famous crossing, historic navigation channels, Native American and colonial archeological sites, and 19th century mills.
