Joe Louis barely survives Billy Conn — championship's most dramatic defense

On June 18, 1941, Billy Conn came within two seconds of defeating Joe Louis for the heavyweight championship, outboxing the champion through 12 rounds before being knocked out in the 13th when he abandoned his strategy to trade punches. The fight — Louis's most dramatic championship defense — drew a gate of over $450,000 and became one of the most celebrated bouts in boxing history.
