The Battle of Sacred Harmony began when the sixty-two warships of Profound Solitude attacked the planet's defense fleet without warning; Sacred Harmony's defense fleet, under Fleet Master Zhar 'Mortumee, was caught off guard and lost two destroyers and three frigates to the Jiralhanae's unprovoked attack. 'Mortumee's remaining fleet of thirty-four ships promptly moved to engage, rapidly destroying five Jiralhanae frigates and damaging three more. Separatist ship masters Isna 'Umamee and Sala 'Vadumee quickly followed suit, damaging two of Profound Solitude's ships (a light cruiser and heavy destroyer). Despite the defenders' quick success, the Jiralhanae still badly outnumbered the Sangheili; Fleet Master Toragus, confident of victory, dispatched a number of his light cruisers and frigates to invade Sacred Harmony with a sizable ground army. Commanded by War Chieftain Faralgus and comprising Jiralhane, Kig-Yar, Yanme'e, and Unggoy, the army successfully landed and engaged the defenders of Sacred Harmony's cities.
