Order 66

Order 66, also known as Clone Protocal 66, was a series of contingency orders of the Clone Soldiers of the Grand Army of the Republic. The order was that the Jedi Commanders and Generals of the Republic military were to be branded as traitors and were to be executed. The order was formally carried out by Supreme Chancellor Sheeve Palpatine in 19 BBY at the very end of the Clone Wars and lead to the destruction of the Jedi Order and the deaths of the majority of the Jedi and lead to the rise of the Galactic Empire.

Description
Order 66: In the event of Jedi officers acting against the interests of the Republic, and after receiving specific orders verified as coming directly from the Supreme Commander (Chancellor), GAR commanders will remove those officers by lethal force, and command of the GAR will revert to the Supreme Commander (Chancellor) until a new command structure is established.

Overview
Order 66 was one of the various orders that was programmed into the minds of all Clone Soldiers that were bread as one of the various contingency oders that were programmed into the minds of the Clone Soldiers that were to be carried out upon its execution. It branded all Jedi Knights and members of the order as traitors and were to be executed as well. The command was placed within the inhibitor chips that all Clone soldiers had placed within them in order to make sure that all active Clone soldiers were to carry them out without hesitation. The order came after Order 65 which branded the Supreme Chancellor as a traitor and was to be removed and executed as well.

First Report
The first report of Order 66 being carried out was in 20 BBY when Clone Trooper Tup, had his chil malfunction and carry out the order prematurally. During the Battle of Ringo Vindo, Tup saw Jedi General Tiplar and walked towards her where he put up his weapon and shot her without hesitation. Her death led to the loss of Republic momentum and forced the Republic forces to withdraw from the combat zone. Tup was later brought onboard a ship to be brought back to Kamino for investigation but was captured by the Separatist forces but later liberated by the Republic. ARC Trooper Fives and 501st Commander Rex had launched their own private investigation and later found out what was really happening. Fives later attempted to tell Anakin Skywalker about what was going on but he was shot by Fox before he could do so and Rex became one of the only few clones to know about the order before its ordered execution.

Execution of the Order
After the attempted coup by Mace Windu and the Jedi Council against Palpatine, he would later use it as a justification to carry out the order citing it as an act against the Republic. After Anakin Skywalker came in and Palpatine made him his apprentice, he would later order the execution of Order 66 to Commander Cody of the 212th Batallion while he was on Utapau. Cody followed through with the order and ordered an AT-TE to fire upon Jedi General Obi Wan Kenobi which nearly killed him but didn't. This would soon began Order 66 as other commanders would be given the same order all across the galaxy.

After the attempt on Obi Wan's life, Commader Bacara and the Galactic Marines were also given the order. During the Battle of Mygeeto, the longest battle of the Clone Wars, Ki-Adi Mundi was leading a small detatchment of Marines against the forces of the Separatist Droid Army on a bridge when the order was carried out. He charged at the Separatist forces but stopped after he saw Bacara and a small group of Galactic Marines raise their arms on him. Confused, he qucikly began deflecting the blasts after the clones began to fire on him but it was too much and Mundi was shot down and killed by his forces.

On the planet of Felucia, Ayla Secura became the next victim as her forces, lead by Commander Bly, turned on her as well. During the Battle of Felucia in an attempt to rescue Barris Offe and push the Separatist forces off the world, Secura stared down a convoy of Homing Spider Droids and Armoured Assault Tanks when she saw her troops raise their weapons at her. She tried to stop it but they were too fast and she was shot down and killed. According to records, her forces admired her greatly and wanted to give her a quick death as they were unable to deal with the pain because of how she saved them from certain death during the war.

Plo Koon became the next victim following Secura. During the Battle of Cato Nemoidia, Plo Koon was in his starfighter and was accompanied by two ARC-170s during an air battle where they were flying over the bridge cities. Palpatine gave out the order and Captain Jag carried it out. Without hesitation, Jag and the other pilots opened fire on Plo Koon and was quickly shot down and crashed on a nearby building on one of the bridge cities.

During the Siege of Selucami, Jedi General Stass Allie was on a BARC speeder bike and was accompanied by two clone troopers. Commander Neyo, one of the troopers present, had gotten the order and he and the other clone had backed up their bikes and fired on their Jedi Commander. The bike was destroyed and she was killed in the process with the remants of the bike landing into the swamps of Selucami littered with the remains of fallen clones and droids during the battle.
