In the ethics of war a similar though less marked development in moral feeling is traceable. Aside from the relapse into the practices of savagery under the malign influence of the Peloponnesian War, there was throughout Greek history a slow but steady amelioration of the primitive barbarities of warfare. In the Homeric Age moral feeling had hardly begun to exercise its influence in humanizing war and in setting limits to the rights of the conqueror. The Greeks of Homer were in some respects almost on the level of savages in their war practices. The life of the captive was in the hands of his captor, and he might be slain without offense to the common conscience. Women and children were, as a matter of course, appropriated by the conqueror or sold into slavery. Homer relates as something to be gloried in, how his hero Achilles dragged the body of Hector around the walls of Troy. Such an act of savagery evidently stirred in the poet’s listeners no feelings of reprobation.[488] In the historical period the mitigation of the barbarities of war was, after the protection of the sanctuary of Apollo at Delphi, a chief object of the celebrated Amphictyonic League. The oath taken by the members of the league included the following engagement: “We will not destroy any Amphictyonic town, nor cut it off from running water, in war or in peace.” This was one of the most noteworthy efforts in antiquity to lay restraint upon the primitive license of war. Limits are set to the rights of the conqueror. War begins to have rules. From the words which Thucydides puts into the mouth of the Platæans at the beginning of the Peloponnesian War, we gather that at that time the common sentiment of Hellas condemned the slaughter of prisoners of war.[489] At Athens this sentiment had found embodiment in the laws, which forbade the slaying of war captives. But under the demoralizing influences of the long and bitter struggle between Sparta and Athens, the little gain which had been made in the humanizing of war during the preceding centuries was lost. Prisoners of war were sold into slavery or killed without the least offense being given to the numbed conscience of Hellas.[490] Even the terrible massacre, toward the end of the war, of the four thousand Athenian prisoners at Ægospotami, by the Spartan Lysander, awakened no protest in Greece at large.[491] Never has “the moral damage of war” had a more tragic illustration.[492]
