Though such was the present temper of the Athenian troops, Nikias could doubtless have spurred them on and accelerated the operations, had he himself been convinced of the necessity of doing so. Hitherto, we have seen him always overrating the gloomy contingencies of the future, and disposed to calculate as if the worst was to happen which possibly could happen. But a great part of what passes for caution in his character, was in fact backwardness and inertia of temperament, aggravated by the melancholy addition of a painful internal complaint. If he wasted in indolence the first six months after his arrival in Sicily, and turned to inadequate account the present two months of triumphant position before Syracuse, both these mistakes arose from the same cause; from reluctance to act except under the pressure and stimulus of some obvious necessity. Accordingly, he was always behindhand with events; but when necessity became terrible, so as to subdue the energies of other men, then did he come forward and display unwonted vigor, as we shall see in the following chapter. But now, relieved from all urgency of apparent danger, and misled by the delusive hopes held out through his correspondence in the town, combined with the atmosphere of success which exhilarated his own armament, Nikias fancied the surrender of Syracuse inevitable, and became, for one brief moment preceding his calamitous end, not merely sanguine, but even careless and presumptuous in the extreme. Nothing short of this presumption could have let in his destroying enemy, Gylippus.[385] [385] Plutarch, Nikias, c. 18. That officer—named by the Lacedæmonians commander in Sicily, at the winter-meeting which Alkibiadês had addressed at Sparta—had employed himself in getting together forces for the purpose of the expedition. But the Lacedæmonians, though so far stimulated by the representations of the Athenian exile as to promise aid, were not forward to perform the promise. Even the Corinthians, decidedly the most hearty of all in behalf of Syracuse, were yet so tardy, that in the month of June, Gylippus was still at Leukas, with his armament not quite ready to sail. To embark in a squadron for Sicily, against the numerous and excellent Athenian fleet now acting there, was a service not tempting to any one, and demanding both personal daring and devotion. Moreover, every vessel from Sicily, between March and June 414 B.C., brought intelligence of progressive success on the part of Nikias and Lamachus, thus rendering the prospects of Corinthian auxiliaries still more discouraging.
