In 1851, Emanuel Leutze painted General Washington and his army crossing the freezing Delaware River on the night of December 25, 1776 on their way to successfully attack the Hessian mercenary garrison at Trenton, New Jersey. That painting became one of the great icons of American historical art.
It was not, however, an accurate depiction of the event. So artist Mort Kunstler completed detailed research on the actual crossing and cataloged the errors in Leutze's painting. Then he created the above painting, which he thinks best represents that frozen night's journey across the river.
