The attempted assassination of Emperor Palpatine was a event that happened during the Anaxes Massacre. During this event Palpatine was giving a speech to the people of the Galactic Empire regarding the Anaxes Search and Rescue Team, when several Consortium Defilers barged in and shot him, but thanks to Palpatine's forces, they were evaded their shots and several Axis troopers killed 4 of the Defilers. The initial reaction to the event was mixed, as simultaneously the March 13th Massacre occurred. Thus it didn't get out to the public that the Emperor had not been until after the event. By that time he was already in the operating room.
