Siege at Kolaar
From Halopedia, the Halo wiki
In March 2553, an attempted Jiralhanae insurrection in Ontom led Avu Med 'Telcam, leader of the Servants of the Abiding Truth, to the decision for an immediate assault on the state of Vadam. Along with nine ships and forces from Nuan keep and Rtova keep, 'Telcam commanded the assault from the frigate Unflinching Resolve.
Eventually, however, the Unflinching Resolve suffered a direct hit and crash-landed. Despite being caught off-guard it appeared as though the Arbiter would be victorious, however, news spread that he allowed humans to land on Sanghelios; this caused many keeps to ally with the Servants of Abiding Truth and the tide turned in their favor. The Arbiter was caught off guard and when his own reinforcements couldn't arrive on time, he reluctantly accepted Admiral Terrence Hood's offer for help in fending off the attackers. The tide turned when the UNSC's new flagship, UNSC Infinity, arrived over Sanghelios and destroyed the rebel destroyer Defender of Faith before finishing off the rebel ground forces with a MAC round.
After the battle, 'Vadam entered talks to board Infinity. The remnants of the Servants of the Abiding Truth escaped to New Llanelli to regroup. One month later 'Telcam said he would remain on New Llanelli until he convinced more keeps to join his cause or get enough ships to destroy those who refuse. 'Telcam would eventually be assassinated by SPARTAN-G059 in January 2558 and the Servants would fall under the leadership of Dural 'Mdama by the time of the Created conflict.
