Macbeth is inside the castle at Dunsinane. He has the gates barred and waits for the army to come. While the wood stays where it is, he believes, he cannot lose.
The number of people inside keeps falling. Names of men who have gone over come in several times a day. He shouts at whoever brings the report.
He calls for his armour and then says to put it by. He behaves like a man who does not know what he is preparing for. Outside the walls the leaves are moving.
