What does Genesis 14:11 mean?

The five kings of the city-states grouped near the southern end of the Dead Sea, including Sodom and Gomorrah, took their stand against their eastern overlords. They lost. In fact, their loss seems to be so thorough that the Bible makes no mention of the battle itself. Instead, the narrative skips directly to the aftermath, which includes the rebellious forces fleeing into tar pits and hiding in the wilderness. The four kings of the east literally sent the forces of the five rebellious kings running.

Afterwards, the forces of the eastern kings looted the cities of Sodom and Gomorrah for all their possessions and provisions, leaving the people destitute. Among those taken in this plunder are Lot, the nephew of Abram, who has recently moved into Sodom (Genesis 13:10–12; Genesis 14:12).
