"Wherever our armies have marched, wherever they have encamped, every species of barbarity has been executed. We planted an irrevocable hatred wherever we went, which neither time nor measure will be able to eradicate." - Col. Charles Stuart, 1778

In accordance with this proud American tradition, President Lincoln instituted the first formal code of conduct for the humane treatment of prisoners of war in 1863. Lincoln's order forbade any form of torture or cruelty, and it became the model for the 1929 Geneva Convention. Dwight Eisenhower made a point to guarantee exemplary treatment to German POWs in World War II, and Gen. Douglas McArthur ordered application of the Geneva Convention during the Korean War, even though the U.S. was not yet a signatory. In the Vietnam War, the United States extended the convention's protection to Viet Cong prisoners even though the law did not technically require it.
