Let the one fight for his flag, and the other for his ideal, and let them both imagine that they are fighting for the country; the strife will be colossal.
[tr. Wilbour (1862)]

Let one fight for his flag and the other combat for his ideal, and let them both imagine that they are contending for their country, and the struggle will be colossal.
[tr. Wraxall (1862)]

Let the one fight for his flag, and the other for his ideal, and let them both imagine they are fighting for the country; the strife will be colossal.
[tr. Wilbour/Fahnestock/MacAfee (1987)]

Let the one fight for his flag and the other for his ideal, and let both imagine they are fighting for their country. The struggle will be tremendous.
[tr. Donougher (2013)]

And as the floods of troubled air to pitchy storms increase
That after thunder sweeps the fields, and ravish up the seas,
Encount’ring with abhorréd roars, when the engrosséd waves
Boil into foam, and endlessly one after other raves;
So rank’d and guarded th’ Ilians march’d; some now, more now, and then
More upon more, in shining steel; now captains, then their men.
[tr. Chapman (1611), l. 711ff]

As when from gloomy clouds a whirlwind springs,
That bears Jove’s thunder on its dreadful wings,
Wide o’er the blasted fields the tempest sweeps;
Then, gather’d, settles on the hoary deeps;
The afflicted deeps tumultuous mix and roar;
The waves behind impel the waves before,
Wide rolling, foaming high, and tumbling to the shore:
Thus rank on rank, the thick battalions throng,
Chief urged on chief, and man drove man along:
Far o'er the plains in dreadful order bright,
The brazen arms reflect a beamy light.
[tr. Pope (1715-20)]

The march of these at once, was as the sound
Of mighty winds from deep-hung thunder-clouds
Descending; clamorous the blast and wild
With ocean mingles; many a billow, then,
Upridged rides turbulent the sounding flood,
Foam-crested billow after billow driven,
So moved the host of Troy, rank after rank
Behind their Chiefs, all dazzling bright in arms.
[tr. Cowper (1791), l. 964ff]

But they marched like unto the blast of boisterous winds, which rushes down to the plain, urged by the thunder of father Jove, and with a dreadful tumult is mingled with the ocean; and in it rise many boiling billows of the much-resounding sea, swollen, whitened with foam, first indeed some and then others following. So the Trojans, first indeed some in battle array, and then others glittering in brass, followed along with their leaders.
[tr. Buckley (1860)]

Onward they dash’d, impetuous as the rush
Of the fierce whirlwind, which with lightning charg’d,
From Father Jove sweeps downward o’er the plain:
As with loud roar it mingles with the sea,
The many-dashing ocean’s billows boil,
Upheaving, foam-white-crested, wave on wave;
So, rank on rank, the Trojans, closely mass’d,
In arms all glitt’ring, with their chiefs advanc’d.
[tr. Derby (1864)]

And these set forth like the blast of violent winds, that rushes earthward beneath the thunder of Zeus, and with marvellous din doth mingle with the salt sea, and therein are many swelling waves of the loud roaring sea, arched over and white with foam, some vanward, others in the rear; even so the Trojans arrayed in van and rear and shining with bronze, followed after their leaders.
[tr. Leaf/Lang/Myers (1891)]

They flew forth like the blasts of some fierce wind that strike earth in the van of a thunderstorm -- they buffet the salt sea into an uproar; many and mighty are the great waves that come crashing in one after the other upon the shore with their arching heads all crested with foam -- even so did rank behind rank of Trojans arrayed in gleaming armour follow their leaders onward.
[tr. Butler (1898)]

And they came on like the blast of direful winds that rusheth upon the earth beneath the thunder of father Zeus, and with wondrous din mingleth with the sea, and in its track are many surging waves of the loud-resounding sea, high-arched and white with foam, some in the van and after them others; even so the Trojans, in close array, some in the van and after them others, flashing with bronze, followed with their leaders.
[tr. Murray (1924)]

They went on, as out of the racking winds the stormblast
that underneath the thunderstroke of Zeus-Father drives downward
and with gigantic clamour hits the sea, and the numerous
boiling waves along the length of the roaring water
bend and whiten to foam in ranks, one upon another;
so the Trojans closing in ranks, some leading and others
after them, in the glare of bronze armor followed their leaders.
[tr. Lattimore (1951)]

Men charged like rough winds in a storm launched on Earth in thunder of Father Zeus, when roaring high the wind and ocean rise together; swell on swell of clamorous foaming see goes forward, snowy-crested, curling, ranked ahead and ranked behind: so line by compact line advanced the Trojans, glittering in bronze behind their captains.
[tr. Fitzgerald (1974)]

The Trojans attacked like a blast of a sudden squall
that swoops down to earth with lightning and thunder, churning
the dark sea into a fury, and countless waves
surge and toss on its surface, high-arched and white-capped,
and crash down onto the seashore in endless ranks:
just so did the Trojans charge in their ranks, each battalion
packed close together.
[tr. Mitchell (2011)]

And they went in like a maelstrom of quarrelsome winds
that goes earthward beneath Father Zeus’ thunderbolt
and with an inhuman din churns with the salt sea, the many
roiling waves of the greatly-roaring ocean
cresting, flecked with white, some before, and others hard behind;
So too the Trojans were packed together, some before, others hard behind.
[tr. Mendelsohn (2011)]
