Famine and faction were the allies on whom besiegers relied. The generals of that time trusted to the operation of these sure confederates as soon as they could establish a complete blockade. They rarely ventured on the attempt to storm any fortified post; for the military engines of antiquity were feeble in breaching masonry before the improvements which the first Dionysius effected in the mechanics of destruction; and the lives of spearmen the boldest and most high-trained would, of course, have been idly spent in charges against unshattered walls.
A city built close to the sea, like Syracuse, was impregnable, save by the combined operations of a superior hostile fleet and a superior hostile army; and Syracuse, from her size, her population, and her military and naval resources, not unnaturally thought herself secure from finding in another Greek city a foe capable of sending a sufficient armament to menace her with capture and subjection. But in the spring of 414 B.C., the Athenian navy was mistress of her harbor and the adjacent seas; an Athenian army had defeated her troops, and cooped them within the town; and from bay to bay a blockading wall was being rapidly carried across the strips of level ground and the high ridge outside the city (then termed Epipolæ), which, if completed, would have cut the Syracusans off from all succor from the interior of Sicily, and have left them at the mercy of the Athenian generals. The besiegers' works were, indeed, unfinished; but every day the unfortified interval in their lines grew narrower, and with it diminished all apparent hope of safety for the beleaguered town.
Athens was now staking the flower of her forces, and the accumulated fruits of seventy years of glory, on one bold throw for the dominion of the Western world. As Napoleon from Mount Cœur de Lion pointed to St. Jean d'Acre, and told his staff that the capture of that town would decide his destiny and would change the face of the world, so the Athenian officers, from the heights of Epipolæ, must have looked on Syracuse, and felt that with its fall all the known powers of the earth would fall beneath them. They must have felt, also, that Athens, if repulsed there, must pause forever from her career of conquest, and sink from an imperial republic into a ruined and subservient community.
