From Wookieepedia, the Star Wars wiki.
The Battle of Cartao was fought in 21 BBY during the Clone Wars over the use of a secondary cloning facility owned by Spaarti Creations. Coming across a planet called Cartao, Palpatine "discovered" Spaarti cloning cylinders, and sent a force led by Kinman Doriana there. It was a victory for the Galactic Republic.
During the battle, Jedi General Fyefee Tiis used his ship, the Whipsaw, to disable the Separatist Droid Control Ship orbiting Cartao, thus giving the Republic's ground forces advance time before the Separatist droid army could be activated. Doriana managed to ram remotely controlled Republic assault transport into the Spaarti facility, destroying the majority of it—and pinning the civilian loss of life on the Jedi Order. The planet Cartao was left ravaged by the battle. Almost all of the cloning cylinders were destroyed. Palpatine took the surviving ones to Wayland and Byss.
