armament, or let the one now in Sicily return to Athens, and especially beseeching them to relieve him from his command, for which he was incapacitated by disease. XX. The Athenians had long before proposed to send out a reinforcement to the army in Sicily, but as all had gone on prosperously, the enemies of Nikias had contrived to put it off. Now, however, they were eager to send him assistance. It was arranged that Demosthenes should employ himself actively in getting ready a large force, to go to reinforce Nikias in the early spring, while Eurymedon, although it was winter, started immediately with a supply of money, and with a decree naming Euthydemus and Menander, officers already serving in his army, to be joint commanders along with him. Meanwhile, Nikias was suddenly attacked by the Syracusans both by sea and land. His ships were at first thrown into confusion, but rallied and sank many of the enemy, or forced them to run on shore; but on land Gylippus managed at the same time to surprise the fort of Plemmyrium, where there was a magazine of naval stores and war material of all kinds. A considerable number of the garrison, also, were either slain or taken prisoners; but the most serious result was the stoppage of Nikias's supplies, which heretofore had been easily and quickly brought through the Great Harbour, while it remained in the hands of the Athenians, but which now could not reach his camp by sea without a convoy and a battle.[2] Moreover, the Syracusan fleet had not been defeated by any superiority of force of the Athenians, but by the disorder into which it had been thrown by pursuing the enemy. They therefore determined to renew the conflict with better success. Nikias, on his part, was unwilling to fight a second time, thinking it was folly to fight with a diminished and disheartened force when he knew that Demosthenes was hurrying to his aid with a large and unbroken armament. However, Menander and Euthydemus, the newly-elected generals, were eager to distinguish themselves by performing some brilliant action before the arrival of Demosthenes, and to eclipse the fame of Nikias himself. The pretext they used was the glory of Athens, which they said would be dishonoured for ever if they should now appear afraid to accept the Syracusans' offer of battle. The battle was fought: and the Athenian left wing, we are told by Thucydides, was utterly defeated by the skilful tactics of the Corinthian steersman Aristion. Many Athenians perished, and Nikias was greatly disheartened, for he had now proved unfortunate both when sole commander and when acting with colleagues.
