Now when the herald saw the arms taken from the Ambraciots who came from the city, he was amazed at their number; for he did not know of the recent disaster, but thought that the arms belonged to the men of his own division.
And someone asked him why he was amazed, and how many of his comrades had been slain, the questioner on his part supposing that the herald had come from the forces which had fought at Idomene.
The herald answered, “About two hundred.” The questioner said in reply, “These arms, though, are clearly not those of two hundred men, but of more than a thousand.” And again the herald said, “Then they are not the arms of our comrades in the battle.” The other answered, “They are, if it was you who fought yesterday at Idomene.” “But we did not fight with anyone yesterday;
it was the day before yesterday, on the retreat.” “And it is certain that we fought yesterday with these men, who were coming to your aid from the city of the Ambraciots.” When the herald heard this and realized that the force which was coming to their relief from the city had perished. he lifted up his voice in lamentation and, stunned by the magnitude of the calamity before him, departed at once, forgetting his errand and making no request for the dead.
