Right behind them
the two Aeantes held the Trojans off as a wooded rocky ridge
stretched out across an entire plain holds back a flood,
fighting off the killer-tides of the mounting rivers,
beating them all back to swamp the lowland flats –
none of their pounding waves can make a breakthrough.
So the two Aeantes kept on beating the Trojans off.

– Homer

The Iliad, Book 17, lines 837-843. As Menelaus and Meriones carry away the corpse of Patroclus, Great Ajax and Little Ajax hold off the Trojans. Homer in a simile likes this to a rocky ridge acros a plain holding back a flood.
