Many of us give only a moment’s thought about the environment when considering the War of Independence: the slope of Breed’s Hill, the ice-choked Delaware River, and diseases such as smallpox.

Join us as David Hsiung, in conversation with Joyce Chaplin, discusses the intricate and often surprising ways in which the natural environment and the war changed each other.
