William Henry Johnson, commonly known as Henry Johnson, was a United States Army soldier who performed heroically in the first African American unit of the United States Army to engage in combat in World War I. On watch in the Argonne Forest on May 14, 1918, he fought off a German raid in hand-to-hand combat, killing multiple German soldiers and rescuing a fellow soldier while suffering 21 wounds, in an action that was brought to the nation's attention by coverage in the New York World and The Saturday Evening Post later that year. On June 2, 2015, he was posthumously awarded the Medal of Honor by President Barack Obama in a ceremony at the White House.

The Croix de guerre 1914–1918 was a French military decoration, the first version of the Croix de Guerre. It was created to recognize French and allied soldiers who were cited for valorous service during World War I, similar to the British mentioned in dispatches but with multiple degrees equivalent to other nations' decorations for courage.
