- "Generals, I regret to inform you that the situation here is grave. While my people remain loyal to the Republic, the Separatists are making advances on the system, and may soon threaten our home planet."
- ―King Yos Kolina, to Generals Plo Koon and Anakin Skywalker
The Mission to Iceberg Three occurred in 21 BBY during the Clone Wars, following General Grievous's Separatist invasion of the Calamari system. In response to this, the Jedi dispatched Plo Koon, CC-3636, and a Jedi Knight to stop the invasion forces for Iceberg III. While the attack on Iceberg Three was halted, and the Republic's base and the natives of Iceberg III were saved, the events eventually led to full-scale conflict on Mon Calamari.
- "The situation here is worse than we expected. Only one planet stands between the Separatists and our base, and we need your help to fight through the enemy fleet."
"This got real messy real fast. We need to punch a hole through that invasion fleet so we can reach Iceberg Three in one piece. Are you ready for launch?"
- ―Plo Koon and Commander Wolffe to the Jedi Knight prior to the battle
Shortly after Yos Kolina spoke with Plo and Anakin, the Republic base on Iceberg III reported a Separatist fleet was within attack range. The Jedi responded by sending a Republic fleet led by Plo Koon and Commander Wolffe, but upon arrival, they found the Separatists had already blockaded the planet. Plo turned to the Jedi Knight, who led a Starfighter attack and managed to punch a hole through the fleet with minimal casualties, and then rendezvoused with Plo at the Republic outpost in sector 327.
Upon arrival, Plo Koon required to make contact with the Jedi High Council to inform them of the Republic's slipping hold on the Calamari system, Commander Wolffe and the Jedi Knight took a single LAAT/i gunship to the last standing Communications Tower on the comet, and pushed through the heavy fire of the large amounts droid forces already on the surface, including Vulture Droids, Hyena-class bombers, Droid tri-fighters, along with multiple ground units. Once they had relayed the news of Grievous's invasion to the High Council, Wolffe and the Jedi Knight returned to the Republic outpost.
With the battle becoming far too intense, Plo Koon decided to evacuate the natives of the area to the safety of his Attack Cruiser. However, General Grievous intended to capture the refugees, and sent many of his forces, including ranks of BX-series droid commandos, Single Trooper Aerial Platforms, AATs, DSD1 dwarf spider droids, and NR-N99 Persuader-class droid enforcers, in a C-9979 landing craft to stop the transports loaded with the refugees from leaving the planet. In counter it, Wolffe had his engineers prepare blaster turret defense platforms, and placed them, along with the troopers of Wolfpack, under the command of the Jedi Knight to stop the droids' advance, while Plo engaged the Separatist fleet in orbit. Wolffe and the troopers of Wolfpack defended the two paths leading to the outpost alongside the Jedi, and only stopping to re-supply with ammunition. Wolffe and the Jedi Knight were able to hold off the invaders long enough for all three waves of the Republic's refugee transports to safely launch from the base.
Once all the droids had been pushed back, and the refugees moved safely, Commander Wolffe prepared a LAAT gunship to leave the planet before Grievous could send reinforcements. However, just as the 104th Battalion prepared to retreat from Iceberg III, Grievous landed at the outpost to personally lead his forces to victory. Wolffe and his men left the task of battling Grievous to the Jedi Knight, who managed to defeat the Separatist General in a one-on-one lightsaber duel. Swiftly defeating him, Grievous retreated to his fleet, as did Wolffe and the Jedi Knight.
- "I regret that I only have sad news to greet you with. King Yos Kolina of the Mon Calamari has been assassinated, and as a result the planet is on the brink of a civil war."
- ―Plo Koon, to the Jedi Knight
While Droids on Iceberg III had been repelled, the Republic was not able to expel Grievous's forces from the system. In addition to this, the Jedi soon learned that King Yos Kolina had been assassinated, and consequentially, the tension between the Mon Calamari and the Quarren on Dac had greatly increased, nearing the point of civil war. In response, the Republic sent ambassadors, Senator Padmé Amidala and Jedi Knight Anakin Skywalker, to stabilize the conflict. The Confederacy, however, had dispatched an envoy of their own: Karkarodon, Riff Tamson. Amidala and Skywalker failed to prevent hostilities, with Tamson provoking the Quarren and rallying them in an assault against the Mon Calamari, leading to the Battle of Mon Cala.
