“This disease is beyond my practice,” said the doctor: “yet I have known those that have walked in their sleep who have died holily in their beds.”
“Wash your hands; put on your nightgown, look not so pale!” muttered Lady Macbeth. ”I tell you yet again, Banquo is buried; he cannot come out of his grave. To bed, to bed! There’s knocking at the gate. Come, come, come, come, give me your hand. What’s done cannot be undone. To bed, to bed, to bed!” And, with a gesture as if she were dragging some invisible person reluctantly after her, Lady Macbeth took up her taper and slowly retreated.
The strain of this unceasing remorse by day and night was too much even for Lady Macbeth’s dauntless courage, and the days of her life were soon to be numbered.
Macbeth himself was bordering on a state of frenzy. Some said he was mad; others, who hated him less, called it valiant fury. Whichever it might be, certain it was that his excitement was beyond control, and that he could not direct his cause in a reasonable manner. Sick at heart, void of all hope, he yet summoned all his courage, and resolved to fight stubbornly to the end, like some savage animal brought to bay.
The English troops, led by Malcolm and Macduff, were close at hand, and the Scottish nobles with their followers were to meet them near Birnam Wood. From here the combined forces were to march on Dunsinane Castle, where Macbeth now was, and which he had strongly fortified.
Rumours of the enemy’s might filled the air, but Macbeth, trying to reassure himself with the witches’ prophecy, bade his people bring him no more reports.
“Till Birnam Wood remove to Dunsinane, I cannot quail with fear,” he declared. “What’s the boy Malcolm? Was he not born of woman? The spirits that know all mortal consequences have said to me thus: ‘Fear not, Macbeth; no man that’s born of woman shall e’er have power upon thee.’”
So, when a white-faced, trembling messenger brought the news that ten thousand English soldiers were marching on Dunsinane, Macbeth silenced him with curses and abuse.
But his momentary rage over, he fell again into dejection.
“I am sick at heart,” he said; “I have lived long enough, my way of life has fallen into the sere, the yellow leaf; and that which should accompany old age, such as honour, love, obedience, troops of friends, I must not look to have; but in their stead, curses not loud but deep, mouth-honour, breath which the poor heart would fain deny, but dare not.”
