During wargames in Louisiana in September 1941, the U.S. Army found itself drawn into a tense firefight with an unseen enemy across the Cane River. The attacker turned out to be three boys with a toy cannon. In this week's episode of the Futility Closet podcast we'll revisit the Battle of Bermuda Bridge and the Prudhomme brothers' account of their historic engagement.

We'll also rhapsodize on guinea pigs and puzzle over some praiseworthy incompetence.
