First battle between Jedi and Sith

The First Battle between Jedi and Sith took place sometime after the exilement of the Exiles and their finding of the Sith and the formation of the Sith Empire. After they found the Sith and became the Lords of the Sith several of the Exiles took the ship they had arrived on and used it to retrace their path to Sith space from the Republic, taking several Massassi warriors, weapons and their new found secrets in Sith Alchemy in an attempt to destroy the Jedi against the orders and will of their leader Ajunta Pall. The battle resulted in their destruction and the Jedi learning of Sith space. PAll would later use the story as a lesson against too much ambition.
