256 THE WALL AND THE FIRST CROSS-WALL [vi cusan generals, seeing that their forces were in disorder and were forming with difficulty, led them back into the city, all but a detachment of the cavalry, who, remaining on the spot, prevented their opponents from gathering stones for the wall, and compelled them to keep together. At length, advancing with one division of their hoplites and all their cavalry, the Athenians attacked the Syracusan horse, whom they put to flight, and killed some of them ; they then erected a trophy. 99 On the following day some of the Athenians proceeded The Syracusans raise with the Construction of nhat part of a stockade and counter- the circle which lay towards the north " ; ^*'^- others began to collect wood and stones and lay them along the intended course of the wall towards Trogilus, where the distance was shortest from the Great Harbour to the outer sea. The Syracusans by the advice of their commanders, chiefly of Hermocrates, determined to risk no more general engagements. They thought it better to raise a counter-wall across the line along which the Athenian wall was building. If they were first they would intercept them. They might indeed be attacked by the Athenians while thus engaged, but then they could oppose them with a part of their army; and there would be time to run a stockade across, if not a wall, before any attack took place. The Athenians on the other hand would have to leave their work, and employ their whole army against them. So they came out and drew a cross-wall, beginning at their own city, from a point below the circle of the Athenian walP', cutting down the olive-trees in the precinct of Apollo and erecting wooden towers. As yet the Athenian ships had not sailed round from Thapsus into the Great Harbour; the Syracusans were still masters of their own coast, and the Athenians - brought their necessaries from Thapsus b}' land. " Or ' that part of their wall which lay to the north of the circle.' Or ' the Athenian circle.'
