There is the “Kettle war” where the only loss was a soup kettle and there is the Emu war with humans vs Emus (which the emus won), however, was there a real war, with at least one real battle, where either no one was killed or the total death total was really, really small, both sides combined?
Small terrorist attacks/counter-terrorist ops and few hour long wars don’t count, also wars that were just declared, but without any actual fighting don’t count, only real wars with at least one real battle count.
A good but dry recap here.

**TLDR Some hysterical (and quite possibly drunk) townsfolk and militia chased after some local natives who decided to skip out on the local hospitality. They parlayed and the runaways decided to return peacefully. In the ensuing celebration the Chief was accidentally killed. 60 years later, the area was named for the non-existent battle.
