Early next morning they started afresh and forced their way to the hill, which had been fortified, where they found before them the enemy's infantry drawn up many shields deep to defend the fortification, the pass being narrow. The Athenians assaulted the work, but were greeted by a storm of missiles from the hill, which told with the greater effect through its being a steep one, and unable to force the passage, retreated again and rested. Meanwhile occurred some claps of thunder and rain, as often happens towards autumn, which still further disheartened the Athenians, who thought all these things to be omens of their approaching ruin. While they were resting Gylippus and the Syracusans sent a part of their army to throw up works in their rear on the way by which they had advanced; however, the Athenians immediately sent some of their men and prevented them; after which they retreated more towards the plain and halted for the night. When they advanced the next day the Syracusans surrounded and attacked them on every side, and disabled many of them, falling back if the Athenians advanced and coming on if they retired, and in particular assaulting their rear, in the hope of routing them in detail, and thus striking a panic into the whole army. For a long while the Athenians persevered in this fashion, but after advancing for four or five furlongs halted to rest in the plain, the Syracusans also withdrawing to their own camp.
