There were six of them, the best and bravest of the hero's companions. Turning back from his post in the bows, Odysseus was in time to see them lifted, struggling, into the air, to hear their screams, the desperate repetition of his own name. The survivors could only look on, helplessly, while Scylla "at the mouth of her cave devoured them, still screaming, still stretching out their hands to me in the frightful struggle." And Odysseus adds that it was the most dreadful and lamentable sight he ever saw in all his "explorations of the passes of the sea." We can believe it; Homer's brief description (the too poetic simile is a later interpolation) convinces us.
Later, the danger passed, Odysseus and his men went ashore for the night and, on the Sicilian beach, prepared their supper—prepared it, says Homer, ‘expertly.’ The Twelfth Book of the Odyssey concludes with these words. “When they had satisfied their thirst and hunger, they thought of their dear companions and wept, and in the midst of their tears sleep came gently upon them.”

Turning back from his post in the bowsというのは、bowsが「矢」で、postが「持ち場」の意味になるのでしょうか？
Later, the danger passed, Odysseus and his men went ashore for the night and, on the Sicilian beach, prepared their supper—prepared it, says Homer, ‘expertly.’
ここのsays Homer, ‘expertly.’というのは、Homerが"Odysseus"を上手く書いた、という意味ですか？ また、prepared their supper—prepared itのハイフンの意味がよくわからない感じです。言い換えているのはなぜなのか？？
お手数をおかけしますが、よろしくお願いします。
