During that mission, Grievous obtained a large kyber crystal and brought it aboard the Dual Hemisphere-Omni Support Vessel. Galactic Republic Jedi Generals Anakin Skywalker and Obi-Wan Kenobi pursued Grievous in a hijacked freighter and boarded the Support Vessel in the freighter's escape pods. As they escaped the freighter, the Jedi steered the doomed starship to ram the Vessel's hyperdrive to prevent Grievous' escape.
After boarding, Kenobi was taken prisoner by Grievous. Two OOM-series security droids told Kenobi they were taking him from his prison cell to the "execution room", leading the Jedi Master to ask in surprise whether they had an entire room dedicated to conducting capital punishment. Kenobi then informed the droids that the Yavin Code required that all prisoners must be blindfolded prior to execution, stalling for time as Anakin came to save him. Skywalker rescued the Jedi Master and destroyed the droids.
Kenobi and Skywalker proceeded to battle Separatist battle droids aboard the Vessel, eventually reaching a group of Armored Assault Tanks. General Kenobi commandeered an AAT, firing its laser cannon at the massive kyber crystal. That caused a massive explosion that eventually engulfed the Omni Support Vessel and much of the Separatist fleet above Utapau. Skywalker and Kenobi escaped aboard a Neimoidian shuttle while Grievous fled into hyperspace on his starfighter Soulless One.
