Battle of the Taskeed system

A battle occured in the Taskeed 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 Sy Myrth system. From Jaminere, the Mandalorians attacked the Taskeed system and went on to raid the Dennogra 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.
