Why the Battle Of Kamino could have gone so WRONG so EASILY

The Battle of Kamino, also known as the Raid on Kamino, was fought during the Clone Wars between the Jedi-led Grand Army of the Galactic Republic and the Droid Army of the Confederacy of Independent Systems. The Separatists launched the battle as one of their key campaigns during the war, hoping to capture Kamino and eliminate the cloning facilities in Tipoca City, thus depriving the Republic from creating more clone troopers for their army. The Separatists, led by GeneralGrievous and Asajj Ventress, were repelled by the Republic.
