The Clone Wars S03E20: Citadel Rescue

After their ship and only way off the planet is destroyed, Anakin and Obi-Wan must lead the escaped prisoners across Lola Sayu's perilous landscape as Plo Koon commands a task force of four cruisers and their fighters through the Separatist defenses in a daring rescue. Even Piell is ravaged by anooba tracking beasts, but before he dies, he passes on his Nexus Routes coordinates to Ahsoka. When the survivors return to Coruscant, Ahsoka knows half the intel, and refuses to disclose it to anyone but the Jedi Council, while Tarkin refuses to hand over his half to anyone other than the Chancellor.
