The country near Dunsinane.
Drum and colours. Enter MENTEITH, CAITHNESS, ANGUS, LENNOX, and Soldiers
MENTEITH
The English power is near, led on by Malcolm,
His uncle Siward and the good Macduff:
Revenges burn in them; for their dear causes
Would to the bleeding and the grim alarm
Excite the mortified man.
ANGUS
Near Birnam wood
Shall we well meet them; that way are they coming.
CAITHNESS
Who knows if Donalbain be with his brother?
LENNOX
For certain, sir, he is not: I have a file
Of all the gentry: there is Siward's son,
And many unrough youths that even now
Protest their first of manhood.
MENTEITH
What does the tyrant?
CAITHNESS
Great Dunsinane he strongly fortifies:
Some say he's mad; others that lesser hate him
Do call it valiant fury: but, for certain,
He cannot buckle his distemper'd cause
Within the belt of rule.
ANGUS
Now does he feel
His secret murders sticking on his hands;
Now minutely revolts upbraid his faith-breach;
Those he commands move only in command,
Nothing in love: now does he feel his title
Hang loose about him, like a giant's robe
Upon a dwarfish thief.
MENTEITH
Who then shall blame
His pester'd senses to recoil and start,
When all that is within him does condemn
Itself for being there?
CAITHNESS
Well, march we on,
To give obedience where 'tis truly owed:
Meet we the medicine of the sickly weal,
And with him pour we in our country's purge
Each drop of us.
LENNOX
Or so much as it needs,
To dew the sovereign flower and drown the weeds.
Make we our march towards Birnam.
Exeunt, marching

In the country near Dunsinane, Malcolm's Scottish allies waited for the approach of the English force he had assembled.

“The English power is near, led by Malcolm, his uncle Siward and the good Macduff,” said Lord Menteith. “They burn for revenge. Their dear causes are summoning them to war so loudly it would stir the dead.”

“We shall meet them near Birnam Wood, that's the way they are coming” said Lord Angus.

“Does anyone know if Donalbain is with his brother?” asked Lord Caithness.

“For certain, sir, he is not,” said Lord Lennox. “I've a list of all the gentry. There is Siward's son and many untested youths, getting their first taste of this man's world.”

“What's the tyrant up to?” asked Menteith.

“He has fortified Dunsinane,” said Caithness. “Some say he's mad. Others, with fewer reasons to hate him, say he's in a valiant fury. But for sure, he's lost control of himself and the confidence of many of his forces.”

“Yes,” said Angus, “now he feels his secret murders are sticking to his hands. Constant revolts are the result of his treachery. Those he commands move only in command, not in love or respect. His kingship hangs loose upon him, like a giant's robe on a dwarfish thief.”

“Who can blame his pestered senses for recoiling when everything within him actually condemns itself for being there?” asked Menteith.

They considered this and for a moment they almost pitied Macbeth for his torment.

“Well, let's march on to give our obedience to those who truly deserve it,” said Caithness. “Let's meet Malcolm, the man with the medicine to cure our country's ailments. If need be, let him have every last drop of our blood.”

“Or as much as is needed to water the flower of kingship and drown the weeds! March onwards to Birnam!” said Lennox.
