Syracuse (Second Punic War).
In 213 B.C. Syracuse, then in the hands of the pro-Carthaginian faction, was besieged by the Romans, 25,000 strong, under M. Marcellus, and a fleet under Appius Claudius. The city was defended by a garrison under Hippocrates. The siege is specially notable for the presence in the city of Archimedes, whose military engines played an important part in the defence, especially against the fleet. During the winter, the revolt of other Sicilian towns drew off a portion of the besiegers, and during the spring and early summer of 212, only a partial blockade could be maintained. Then however, taking advantage of a festival in the city, Marcellus stormed and captured the upper portion of the town. An attempt to force the Roman lines by a Carthaginian relieving force, under Himilco, was repulsed, and shortly afterwards the rest of the city was captured by assault.
