The Iliad 16.210–224

So saying, he aroused the strength and spirit of every man, and yet closer were their ranks serried when they heard their king. And as when a man buildeth the wall of a high house with close-set stones, to avoid the might of the winds, even so close were arrayed their helms and bossed shields; buckler pressed on buckler, helm upon helm, and man on man. The horse-hair crests on the bright helmet-ridges touched each other, as the men moved their heads, in such close array stood they one by another. And in the front of all two warriors arrayed themselves for war, even Patroclus and Automedon, both of one mind, to war in the forefront of the Myrmidons. But Achilles went into his hut, and opened the lid of a chest, fair and richly-dight, that silver-footed Thetis had set on his ship for him to carry with him, whem she had filled it well with tunics, and cloaks to keep off the wind, and woollen rugs.
