Operation: Knightfall (LadyVader)

Operation: Knightfall, which took place in 19 BBY immediately before the end of the Clone Wars, was one of the first conflicts of the Great Jedi Purge (LadyVader).

After assisting in the death of Jedi Master Mace Windu(LadyVader) and submitting to the tutelage of Dark Lord of the Sith Darth Sidious (LadyVader) —known to the galaxy as Palpatine, Supreme Chancellor of the Galactic Republic—Jedi Knight Anakin Skywalker (LadyVader) 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 Jedi Order was wiped out.

During the fighting, Vader altered a beacon that alerted Jedi across the galaxy—the ones that had not already fallen to the clones in their ranks—that the Clone Wars were over and ordered them back to the Temple, where a garrison of clone troopers lay in wait to finish them off. All of the Jedi who complied with the beacon's mandate were killed by squads of clones, some of whom were disguised as Jedi themselves. To prevent more deaths, two surviving Jedi Masters, Obi-Wan Kenobi (LadyVader) and Yoda (LadyVader), infiltrated the Temple and switched the beacon, changing the message to ward any surviving Jedi away and instructing them to go into hiding. With the operation's completion, the bodies of the slain Jedi were publicly burned in a massive pyre in front of the Jedi Temple Public Entrance. Vader led the 501st Legion, along with a number of others, and attacked the Jedi Temple. The 90th Division went in first, only killed four Jedi because it was taken by surprise. The 501st went in after that, and fought several hundred Jedi near the Archives.

When most of the Jedi were distracted, the 101st Legion, made up of Paratroopers and Clone Assassins, went in next and put up a beacon that told all of the Jedi to come back to the Temple. A clone assassin squad was sent in to guard the beacon. Obi-Wan Kenobi killed all of the assassins in the squad and took out the beacon. Most of the other Jedi in the Temple were killed.

Aftermath
Commander Typhuss escorted Darth Sidious to the Jedi Temple. As the fighting began to die down, Darth Sidious arrived at the Temple to check on Vader's progress. Vader knelt before his Master and was congratulated by the Dark Lord. The apprentice then traveled to Mustafar to eliminate the leaders of the Confederacy of Independent Systems, a faction opposing the Republic that had seceded three years prior, assembled there by Sidious for "talks" to end the conflict.
