The 319th legion was created 20 years after the regular clones were created. They were made to stop the empire although the 501st heard about them and sent a battalion of storm troopers to destroy their "Evil" brothers. The storm troopers destroyed almost all the clones, but about one hundred escaped. These troopers brought a small batch of DNA samples from clones so that they would be able to clone more troops. The 100 troopers that escaped became 5 legions The 319th led by Commander Trixe, the 216th led by Sergeant Vex, the 999th led by Commander fusion, the 1111th led by Commander Cur, and the 750th led by Commander Tarix. These Legions all combined and made one large 319th Legion. The leaders of these legions fought in the clone wars and were not from the batch made to fight the empire, but they didn't follow order 66 and they joined the 100 clones that got off of Kamino alive, and started fighting against the empire.
