"The Bart of War" is the twenty-first and penultimate episode of the fourteenth season of the American animated television series The Simpsons.

When Ned, Rod and Todd return home and discover the damage caused by Bart and Milhouse, they flee to their panic room and call the police.

Marge subsequently establishes a peer group based on Native American life, called the "Pre-Teen Braves" — composed of Bart, Ralph Wiggum, Nelson Muntz, and Database, with herself as tribe leader after Homer fails in his leadership skills.

At the Isotopes game, in another attempt to defeat the Cavalry Kids, Bart and Homer divert them away from the stadium with a fake "free VIP parking" sign, and the Pre-Teen Braves then disguise themselves as their enemies before singing their own version of "The Star-Spangled Banner".
