For on one side alone the hill gave shelter,
So vast that phalanx of unconquered men, _2435
And there the living in the blood did welter
Of the dead and dying, which in that green glen,
Like stifled torrents, made a plashy fen
Under the feet--thus was the butchery waged
While the sun clomb Heaven's eastern steep--but when _2440
It 'gan to sink--a fiercer combat raged,
For in more           strife the armies were engaged.
