Since the Rose Bowl game became so popular and most of the college football players were fighting overseas during World War I, the Pasadena Tournament of Roses decided to stage the game with military units, with the approval from President Woodrow Wilson. The Camp Lewis football team represented the US Army.
According to the Tournament of Roses, "Within weeks of the 1918 Rose Bowl Game, the majority of the players from both teams were scheduled to go overseas. John Beckett, left tackle for Mare Island, acknowledged this fact and said that “this would be the last battle that we would fight in the name of sports."
