The evening after the battle the 71st Regiment, Frazer's Highlanders, were sent the 10 miles to Wilmington to meet up with the British fleet on the Delaware River and establish a hospital for the wounded. In the course of doing so they found and captured the state treasury, including most of the state papers. They also found President McKinly at home in his bed, and they took him into captivity as well. He was kept as a prisoner of war on the "Roebuck," and later on the "" in the Delaware River.
