History of the Peloponnesian War

The dead lay unburied, and each man as he recognized a friend among them shuddered with grief and horror; while the living whom they were leaving behind, wounded or sick, were to the living far more shocking than the dead, and more to be pitied than those who had perished.

These fell to entreating and bewailing until their friends knew not what to do, begging them to take them and loudly calling to each individual comrade or relative whom they could see, hanging upon the necks of their tent-fellows in the act of departure, and following as far as they could, and when their bodily strength failed them, calling again and again upon heaven and shrieking aloud as they were left behind. So that the whole army being filled with tears and distracted after this fashion found it not easy to go, even from an enemy's land, where they had already suffered evils too great for tears and in the unknown future before them feared to suffer more.
