The First part of King Henry the Fourth — Act 5, Scene 3: Plain between the camps.

King Henry enters the battlefield with his forces, and Douglas mistakes Sir Walter Blunt for the king. Blunt identifies himself as loyal to Henry and refuses to surrender, but Douglas kills him in combat. Hotspur arrives and is pleased to see Douglas’s strength, but Douglas realizes he has killed only a knight dressed like the king, not Henry himself. The two hurry off to continue the fight. Meanwhile, Falstaff appears alone, shaken by the slaughter around him and claiming his men have been destroyed. Prince Henry then demands Falstaff’s sword, but Falstaff tries to stall him and offers a pistol that turns out to be a bottle of sack. The Prince throws it at him and leaves.
