The Tide of Victory (Belisarius)

Led by the supercomputer Link, the Malwa Empire has built a deadly army that nothing on 6th century Earth can beat -- nothing, that is, except Belisarius, the greatest general and military genius of the age. Against overwhelming odds, Belisarius has prevailed in one brilliant victory after another -- but his greatest battle is yet to be fought and this time, the future of mankind is in his hands.
