Battle of the Kaelta system

A battle occured in the Kaelta system during the Mandalorian Wars. In 3,963 BBY, the Mandalorians began their full invasion of Galactic Republic territory. One of the prongs of their asssault sent them through the Quermia system. From Quermia, the Mandalorians attacked the Kaelta system and went on to raid the Florn system.

Behind the scenes
The battle is only referenced once in The Essential Atlas. It is marked on a galactic map showing the course of the Mandalorian Wars rather than described in prose. In the Atlas, the Kaelta system is denoted as the "Toola system" after the planet of Toola, which it contains.
