Taris Siege

The First Battle of Taris was an engagement fought by the Old Republic during the Mandalorian Wars, at some point during or after the year 3,964 BBY, and following the destruction of the planet Cathar. With a growing level of Mandalorian encroachment into the Outer Rim during the period, Republic and Jedi military forces grew increasingly stretched across that region, and were likewise hard-pressed to counter any major planetary assault, were it to occur.

Details remain sketchy, but from what has been revealed in various sources, the Mandalorian invasion occurred during an interval whence the Republic proved unable to successfully defend the planet against a numerically-superior force. A Jedi enclave had been established in the Taris Upper City prior to the invasion, but turmoil gripped the facility in 3,964 BBY after several Jedi students were found murdered, and which may have been a minor precipitating factor, insofar as the buildup of greater historical events were concerned.

Ultimately, the Mandalorians were successful in their conquest of the planet; upon which, it must be noted, were a number of the last Cathar refugee-survivors from the Mandalorian genocide of their species, having fled there some months or years previously. The precise length of the Mandalorian occupation of Taris is as yet unknown, but it would eventually end with the retaking of the planet by the Jedi Knights under the command of Revan, circa 3,961 BBY.
