 The plan was concerted between Eastern Emperor Leo , Western Emperor Anthemius , and General Marcellinus , who enjoyed independence in Illyricum . Basiliscus was ordered to sail directly to Carthage , while Marcellinus attacked and took Sardinia , and a third army , commanded by Heraclius of Edessa , landed on the Libyan coast east of Carthage , making rapid progress . It appears that the combined forces met in Sicily , whence the three fleets moved at different periods .
