In May 1824 Trelawny brought a load of guns to the fortified cave in which Odysseas was based. He arrived with a British military officer, Whitcomb, and a military engineer, Fenton. Trelawny recorded that Odysseas commanded a force of 5,000 men, who killed over 20,000 people during their campaign. Odysseas and his men retired to Parnassus after they learned the Greek government would not give them more funds. The Greek Government had decided to try to raise a regular army and take power away from the warlords. The size of his force soon diminished.
