The Battle of Kamino, a key campaign of the Clone Wars, was fought for control of the planet Kamino in 21 BBY. Which is also known as the Invasion of Kamino or the Defence of Kamino, the battle occurred when the Confederacy of Independent Systems launched a massive assault aimed at crippling the Grand Army of the Republic’s main cloning facilities in Kamino’s capital, Tipoca City. Having collaborated during a thwarted attempt to invade Kamino several months earlier, rivals General Grievous and Dark Acolyte Asajj Ventress were assigned by Count Dooku to lead the Separatist attack on Kamino.
Joining Jedi General Shaak Ti and Prime Minister Lama Su in coordinating the Galactic Republic’s defence of Kamino were Jedi Generals Obi-Wan Kenobi and Anakin Skywalker who, unwilling to lose the vital cloning factories, brought their clone troopers of the 501st Legion to reinforce the Grand Army defences, with General Skywalker leading the Republic's starfighter squadrons.
Dark Acolyte, Asajj Ventress, went after a DNA sample of the Grand Army’s prime clone Jango Fett but was intercepted by Skywalker, who dueled the Dark Acolyte for the DNA sample. In a similar fashion, Grievous was confronted by Kenobi while spearheading a droid assault on Tipoca City’s clone barracks. As the Separatist battle droids pressed further into Tipoca City, Kamino elite Advanced Recon Commandos played a critical part in repulsing the enemy forces from the clone troopers’ homeworld.
Despite heavy losses, the Jedi and clones were able to repel Separatist forces from Kamino, securing a victory for the Galactic Republic and securing the future of the cloning process.
