These symptoms of renewed confidence and energy were observed by Nicias with growing disquiet. And if he turned his eyes to his own camp, he saw little to relieve his anxiety. For the predictions of Lamachus had been fulfilled to the letter. By his fatal policy of procrastination Nicias had frittered away the resources of the most splendid armament that ever set sail from Peiraeus. His soldiers were infected by the despondency of their leader, and many of them were stricken by the marsh-fever which haunts the unwholesome district of the Anapus. Above all the condition of the fleet showed the lamentable effect of long inaction and delay. All the supplies of the Athenians came to them by sea, and in order to keep their communications open, it was necessary to keep the whole of the fleet on constant duty. In consequence of this, the hulls of the triremes had become sodden with water, which made them leaky, and difficult to row. Moreover the crews, which were largely composed of foreign seamen, had grown restive and mutinous under the severe strain of hardships and privation, so different from the easy and lucrative service in the hope of which they had enlisted. Some took the first opportunity of deserting to the enemy, while others ran away to remote parts of Sicily; and there was no means of filling the places thus left vacant.
Such was the burden of care and apprehension which lay heavy on the feeble shoulders of the Athenian general. He was naturally a weak man, haunted by superstitious terrors, irresolute, easily cast down; and this infirmity of character was aggravated by a painful and incurable disease. There was no longer any question of laying siege to Syracuse: he himself was now besieged, and it was all he could do to maintain his position within his defences, and keep the sea open for the conveyance of supplies. In this desperate situation he determined to send a written despatch to Athens. We are led to suppose that this was an unusual proceeding, and that news from the seat of war was generally sent by word of mouth. The document is given at full length, with all its grievous confessions of incompetence and failure. After setting forth the facts of the case as stated above, Nicias insists that one of two things must be done: either the army now lying before Syracuse must be recalled to Athens, or the Athenians must send out a second army, equal in strength to the first, and a general to relieve him of his command.
