Mission to Iceberg Three 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 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 . Aftermath . 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 .
