Cymbeline — Act 5, Scene 2: Field of battle between the British and Roman camps.

The Roman and British armies meet in battle, with Posthumus fighting among the British in disguise as a poor soldier. He defeats and disarms Iachimo, and Iachimo is shaken by his guilt over slandering Imogen, admitting that his shame has weakened him. As the fighting continues, the Britons are driven back and Cymbeline is captured. Belarius, Guiderius, and Arviragus arrive and urge the British to stand their ground, and Posthumus returns to help them, leading to Cymbeline’s rescue. Lucius then reappears with Iachimo and Imogen, but the battlefield is in confusion, and Lucius decides they must either strengthen their forces or flee.

The heaviness and guilt within my bosom

Takes off my manhood: I have belied a lady,

The princess of this country, and the air on't

Revengingly enfeebles me; or could this carl,

A very drudge of nature's, have subdued me

In my profession? Knighthoods and honours, borne

As I wear mine, are titles but of scorn.

If that thy gentry, Britain, go before

This lout as he exceeds our lords, the odds

Is that we scarce are men and you are gods.

Stand, stand! We have the advantage of the ground;

The lane is guarded: nothing routs us but

The villany of our fears.

Stand, stand, and fight!

Away, boy, from the troops, and save thyself;

For friends kill friends, and the disorder's such

As war were hoodwink'd.

'Tis their fresh supplies.

It is a day turn'd strangely: or betimes

Let's reinforce, or fly.
