He remained in Washington in 1860 and kept his friends in South Carolina appraised of the secret military plans or inactivity of the federal government. After the war he returned to Washington to lobby for South Carolina landholders. The remainder of his careers was devoted to a series of diplomatic missions to China, Mexico, and Chile. In 1889 William Henry Trescott was instrumental in the formation of the Pan-American Union.
