We might, however, yet more wonder at another deficiency in Homer’s art of war, were it not still universal throughout those rich and populous countries where mankind was first civilised. Even among the Turks, who, far as they have spread over the finest part of Europe, retain pertinaciously every defect of their ancient Asiatic customs, the easy and apparently obvious precaution of posting and relieving sentries, so essential to the safety of armies, has never obtained. When, in the ill turn of the Grecian affairs, constant readiness for defence became more especially necessary, it is mentioned as an instance of soldiership in the active Diomedes, that he slept on his arms without his tent: but no kind of watch was kept; all his men were at the same time asleep around him: and the other leaders were yet less prepared against surprise. A guard indeed selected from the army was set, in the manner of a modern grand-guard or out-post; but though commanded by two officers high both in rank and reputation, yet the commander-in-chief expresses his fear that, overcome with fatigue, the whole might fall asleep and totally forget their duty. The Trojans, who at the same time, after their success, slept on the field of battle, had no guard appointed by authority, but depended wholly upon the interest which every one had in preventing a surprise; “They exhorted one another to be watchful,” says the poet. But the allies all slept; and he subjoins the reason, “For they had no children or wives at hand.” However, though Homer does not expressly blame the defect, or propose a remedy, yet he gives, in the surprise of Rhesus, an instance of the disasters to which armies are exposed by intermission of watching, that might admonish his fellow-countrymen to improve their practice. The Greeks, and equally the Trojans and their allies, encamped with great regularity; and fortified, if in danger of an attack from a superior enemy. Indeed Homer ascribes no superiority in the art of war, or even in personal courage, to his fellow-countrymen. Even those inland Asiatics, afterwards so unwarlike, are put by him upon a level with the bravest people. Tents, like those now in use, seem to have been a late invention. The ancients, on desultory expeditions, and in marching through a country, slept with no shelter but their cloaks; as our light troops often carry none but a blanket--a practice which Bonaparte extended to his whole army, thereby providing a speedy and miserable death for thousands in his retreat from Russia. When the ancients remained long on a spot they hutted. Achilles’ tent or hut was built of fir, and thatched with reeds; and it seems to have had several apartments.[h] TREATMENT OF ORPHANS, CRIMINALS, AND SLAVES There are two special veins of estimable sentiment, on which it may be interesting to contrast heroic and historical Greece, and which exhibit the latter as an improvement on the former, not less in the affections than in the intellect.
