He well knew that the fortunes of the day had changed, but still stood his ground and tried to protect his comrades.
As when a cloud goes up into heaven from Olympus, rising out of a clear sky when Jove is brewing a gale--even with such panic stricken rout did the Trojans now fly, and there was no order in their going.

Hector's fleet horses bore him and his armour out of the fight, and he left the Trojan host penned in by the deep trench against their will.

Many a yoke of horses snapped the pole of their chariots in the trench and left their master's car behind them.

Patroclus gave chase, calling impetuously on the Danaans and full of fury against the Trojans, who, being now no longer in a body, filled all the ways with their cries of panic and rout; the air was darkened with the clouds of dust they raised, and the horses strained every nerve in their flight from the tents and ships towards the city.
Patroclus kept on heading his horses wherever he saw most men flying in confusion, cheering on his men the while.

Chariots were being smashed in all directions, and many a man came tumbling down from his own car to fall beneath the wheels of that of Patroclus, whose immortal steeds, given by the gods to Peleus, sprang over the trench at a bound as they sped onward.
