What happened with Mace Windu in Episode 3?

Mace Windu deftly parried the first set of slashes that Dark Sidious made who was also known as Empereror Palpatine. Mace Windu counterattacked from an offensive stance known as the Vaapad stance striking blow after blow forcing the evil Sith to back in the corner. Windu new he had to kill this Sith because he had even fooled the wisest of all the Jedi and was all for evil. Windu's saber struck fast in a shoulder-to corner block and Darth Sidious was barely able to block it this time. Sidious knew he had betteer resort to something else and cowardly used force powers at point blank range during the lightsaber battle which was against the jedi code. Despite the cheateful seemngly advantage, Windu's discipline and firce strength on the hilt combined with his faith blocked every bit of force lightning Darth Sidious was firing at him. Windu then began turning the force lightning powers back upon Darth Sidious as it burned his face....all the while Anakin Skywalker was watching....
