There are several unforgettable scenes in the Star Wars Saga, and on of them is Anakin Skywalker, or rather the newly minted Darth Vader, leading thousands of clone troopers up the steps to the Jedi Temple as the lights of the city burned brightly behind them.

I recently read a reference to this as 'Operation Knightfall." The phrase brought a tear to my eye.

Operation Knightfall. A name rich in meaning. The Jedi Knights are falling, it happens under the cover of night, and night is falling on the Republic as its defenders of peace and justice are murdered.

It's also called the Jedi Purge, but it's murder just the same. Clone troopers in the battlefield murder their Jedi commanders; Troopers in the Jedi Temple murder younglings and civilians, while Vader ruthlessly cuts down the innocent children who look to him for help.

Operation Knightfall. The night the Dark Times began and the Empire was born.
