Operation: Knightfall

Operation: Knightfall was was was one of the last military engagements of the Clone Wars and one of the first conflicts of the Great Jedi Purge. After assisting in the death of Jedi Master Mace Windu and submitting to the tutelage of Dark Lord of the Sith Darth Sidious—known to the galaxy as Palpatine, Supreme Chancellor of the Galactic Republic—Jedi Knight Anakin Skywalker fell to the dark side and was anointed Darth Vader. Just afterward, Vader was assigned a detachment of the 501st Legion's clone troopers and was tasked with storming the Jedi Temple on Coruscant alongside them. This massacre, as well as the mandate given to the clones instructing them to kill their Jedi officers in the field, marked the beginning of a galaxy-wide hunt for the Jedi. Most of the Jedi inside the Temple were executed by the invaders while the Temple burned, and within minutes of the Purge's inception, much of the Jedi Order was wiped out.
