The Tragedy of Hamlet, Prince of Denmark — Act 4, Scene 4: A plain in Denmark.

Fortinbras appears with a captain and soldiers marching through Denmark, and sends the captain to tell the Danish king that his army is asking permission to cross his territory on the way to fight in Poland. Hamlet then enters with Rosencrantz and Guildenstern and questions the captain about the force. He learns that the soldiers are heading for a small, worthless patch of Polish land and that two thousand men are risking death for a point of honor. After the captain leaves, Hamlet is deeply shaken by the contrast between Fortinbras’s action and his own delay. Left alone, he reflects that he has cause, will, strength, and means to act, and resolves that from now on his thoughts must be violent or useless.
