annihilate the enemy or to annex his territory. The losses in killed and wounded were by no means as heavy as Mardonius believed, for these were not big battalions directed by invisible generals, but citizen soldiers who were sensible enough to know when they were beaten. The procedure was fixed. The army marched out from the city at dawn until it found itself face to face with the enemy on the traditional battle ground, one of those alluvial plains, comparatively rare in Greece, upon which the city depended for its supply of corn, the prize of victory being indeed the ground on which the fighting took place. Then the generals on either side would address their men with some final words of exhortation (there was a special style of rhetoric held appropriate for such occasions) and the two armies would advance to the attack. With waving plumes and glittering spears, the sun striking upon the gold ornaments of breastplate and sword-belt, the hoplites pushed forward, slowly at first but quickening their step as they approached the enemy, and at last the two lines, moving now at the double, would meet with a crash in the shock of battle. Then came the moment for which the Greek’s whole life was one long preparation: swaying, struggling, heaving, with every muscle tense and every limb engaged, the opposing masses strove to hurl one another back. All the tricks of the wrestling school and the boxing match were designed for use in this hour, and even courage was of little avail unless it was supported by that perfection of physical fitness which the ancient Greeks alone of all nations attained. Success in an ancient battle depended upon the quality of the men engaged, and the men derived little aid from external sources: cavalry, engineers and artillery played no part. The issue was decided by the final shock of two bodies of heavy armed infantry relying on solidity and weight, and momentum in the attack was all important, for the ranks once broken could seldom be reformed. Long training in the drill ground must have been necessary for the orderly advance of formations so dense as these (the average depth of men in the fifth century seems to have been about eight, but at Delium in 421 the Bœtians massed their men in files of twenty-five), and however good the marching there was a constant tendency for the front line to slant as each man edged under his right hand neighbour’s shield. A Greek hoplite like a modern Rugby forward depended upon his formation, and without a comrade on either side of him, and ranks of men behind or in front, he felt himself lost. His formation broken, the natural impulse was to retire, and a withdrawal to the city walls was the usual result of defeat. Once behind his ramparts the citizen soldier was safe, for in the fifth century sieges were costly, tedious, and usually indecisive. Open fighting was the cardinal rule: cunning surprises and unforeseen attacks were as difficult for an
