By the time we'd made our way to the molten surface of Mustafar, it was apparent that Dellso had been a busy little bug. All by his lonesome he'd found a previously-hidden droid factory, fired it up and cranked out his own private army of battle droids. Needless to say, this got the men of the Five-Oh-First ... a little hot under the helmet, and not just because of all that lava. Truth be told we'd all had our fill of those gear heads during the war, and we couldn't stomach the thought of going through another one. So we blew them up -- blew up the droids, blew up the factory ... damn near blew up the planet. - 501st Stromtrooper
