Scotland is at war. King Duncan faces not only his own rebellious kinsmen but also an invasion by King Sweno of the Norwegians. In this scene, Duncan receives three significant reports: the death of the rebel Macdonald at the hands of “brave Macbeth”; Macbeth’s action against the Norwegians; and the treachery of the Thane of Cawdor, who has sided with the enemy. In each case, Macbeth’s heroism shines out, leading to victory for Scotland and surrender by Sweno. Finally, Duncan orders Cawdor’s execution and arranges for his title to pass to Macbeth.
