=185.= The fleet, sailing southward, reconnoitered the defenses of Syracuse, and took possession of Catana, which became its headquarters. At this point, Alcibiades received from Athens a decree of the Assembly, requiring his return for trial. A judicial inquiry had acquitted him of the mutilation of the Hermæ, but he was still charged with profaning the Eleusinian Mysteries, by representing them at his own house for the entertainment of his friends. This was an unpardonable crime, and those noble families which had derived from their heroic or divine ancestors an especial right to officiate in the ceremonies, felt themselves grossly insulted. The public trireme which brought the summons to Alcibiades, was under special orders not to arrest him, but to suffer him to return in his own vessel. The wily general availed himself of this courtesy to effect his escape. Landing at Thurii, he eluded his pursuers, and the messengers returned to Athens without him. Here in his absence he was condemned to death, his property confiscated, and the Eumolpidæ solemnly pronounced him “accursed.” =186.= The Athenians had spent three months in Sicily with so little effect, that the Syracusans began to regard them with contempt. Nicias, thus shamed into attempting something, spread a report that the Catanæans were inclined to expel the Athenians from their city, and thus drew a large army from Syracuse to their aid. During its absence from home, the whole Athenian fleet sailed into the Great Harbor of Syracuse, and landed a force which intrenched itself near the mouth of the Anapus. A battle followed on the return of the Syracusans, and Nicias was successful. Instead of following up this advantage, he retired into winter-quarters at Catana, and afterward at Naxos, while he sent to Athens for a supply of money, and to his Sicilian allies for a re-enforcement of men. The Syracusans spent the winter in active preparation. They built a new wall across the peninsula, between the Bay of Thapsus and the Great Port, covering their city on the west and north-west. They sent, at the same time, to Corinth and Sparta for help, and found in the latter city an unexpected ally. Alcibiades had crossed from Italy to Greece, and had received a special invitation to Sparta. Here he indulged his spite against his countrymen by revealing all their plans, and urging the Spartans to send an army into Sicily to disconcert their movements. [Sidenote: B. C. 414.] =187.= With the opening of spring, Nicias commenced the siege by fortifying the heights of Epipolæ, which commanded the city. He built, also, a fort at Sy´ke, and dislodged the Syracusans from the counter-walls which they were constructing. The Athenian fleet was stationed in the Great Harbor, and the Syracusans, despairing of effectual resistance, sent messengers to arrange terms of surrender. But the brave Lamachus had been slain, and Nicias, now sole commander, was too inactive to seize the victory just within his grasp.
