Tell It to the Marines (1918)

After a busy day of playing pranks on their father's servants and guests, Harry Williams' daughters Jane and Katherine tumble into bed and fall asleep. Having seen a film depicting World War I fighting in Europe, little Jane dreams that two armies, consisting entirely of mechanical dolls, are advancing against each other in battle. While Trik leads the German troops, who are guilty of committing a score of atrocities, Trak heads the Allied army, which ultimately wins the war. In the end, Jane awakens with a start to find that it has all been a dream.
