Prologue: Chapter A - World War I, the Russian Revolution & Woodrow Wilson
The Untold History of the United States
When the narrator talks about the first successful use of poison gas by the Germans at the battle of Ypres, a gun being loaded by gunners in gas masks is shown. At Ypres, the chlorine gas was in fact not deployed by artillery but released from pressure bottles, and gas masks had not yet been invented.
When the narrator tells about the explosion on the USS Maine, the actual sequence shown after the stills of the ship depicts the sinking of the Austro-Hungarian battleship Szent Istvan, not the USS Maine.
