Barnyard Battle, The (film) Mickey Mouse cartoon; released in 1929. Directed by Walt Disney. Enduring a strenuous army physical, Mickey joins up to protect his home from enemy cats. At first he’s one of many Mickey look-alike soldiers, as a machine gunner, using piano keys when he runs out of bullets. Mickey then fights alone against an army of cats, clobbering each with a hammer as they emerge from a tunnel. His fellow soldiers cheer him as a hero.
