Macbeth
In Act 1 Scene 2, there is a war going on. King Duncan is at a camp, listening to reports from the battlefield. An injured officer (some scripts say a captain, others a sergeant) is brought in. He saved Malcolm's life. The officer tells Duncan about the battle. He says that it was going badly, until Macbeth fought his way to the rebel leader Macdonald and disembowelled him. But as soon as that happened, the Norwegians, led by their king Sweno, also attacked. They were joined by a traitor, the Thane of Cawdor. Macbeth and Banquo fought bravely until they were defeated. Duncan is pleased by the news. He orders that the Thane of Cawdor be executed and his title given to Macbeth.
