Battle of the Jaminere system

A battle occured in the Jaminere 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 Lianna system, from which their forces split between those that would attack the Makem system and those that would attack Jaminere. From Jaminere, the Mandalorians attacked the Sy Myrth system.

Behind the scenes
The battle is only referenced once in 2009's The Essential Atlas. It is marked on a galactic map showing the battles of the Mandalorian Wars rather than described in prose.
