The besieged found a source of strength in these large numbers; the assailants an incentive in the prospect of booty. Antonius gave orders that fire should instantly be set to the finest buildings without the city, to see whether the inhabitants of Cremona might not be induced by the loss of their property to transfer their allegiance. Some houses near the walls, which overtopped the fortifications, he filled with the bravest of his soldiers, who, by hurling beams, tiles, and flaming missiles, dislodged the defenders from the ramparts.
