It is the cause that fires the warrior's breast,
Let it be just, or shame will lower his crest.
[tr. Moore (1870), 5.6]

The cause unnerves or nerves the soldier's might,
And shame disarms who strikes not for the right.
[tr. Cranstoun (1875), 5.6]

With soldiers the cause they fight for raises or depresses their strength; if it is not just, shame makes them drop their arms.
[tr. Gantillon (1884), 5.6]

'Tis his cause that makes or mars a soldier's strength. If the cause be not just, shame strikes the weapon from his hands.
[tr. Butler (Loeb) (1912)]

If the cause is not just, men's hands will drop their weapons;
just cause can rally soldiers back to their ranks.
[tr. Carrier (1963)]

It's the cause that breaks or exalts a soldier's strength;
If the cause is unjust, from his hand shame strikes his weapon.
[tr. Musker (1972)]

It is his cause that makes or breaks a soldier's strength; unless his cause is just, shame dashes the weapons from his hand.
[tr. Goold (Loeb) (1990)]

It is their cause that breaks or raises soldiers' strength;
If that is unjust, shame throws down their weapons.
[tr. Lee (1992)]

The cause exalts or breaks a soldier’s strength: unless it is just, shame downs his weapons.
[tr. Kline (2001)]

The cause men that men acclaim will force or limit courage:
shame will press their weapon down.
[tr. Holcombe (2009)]
