Henry's story. Then, says the Chorus, King Henry would "[a]ssume the port [bearing] of Mars". The Chorus encourages the audience to use their "imaginary forces" to overcome the limitations of the stage: "Piece out our imperfections with your thoughts ... turning the accomplishment of many years / Into an hour-glass". Shakespeare's plays are in five acts. In Henry V, the first act deals largely with the king and his decision to invade France, persuaded that through ancestry, he is the rightful heir to the French throne.

At the siege of Harfleur, the English are beaten back at first, but Henry urges them on with one of Shakespeare's best-known speeches. "Once more unto the breach, dear friends, once more; / Or close the wall up with our English dead...." After a bloody siege, the English take Harfleur, but Henry's forces are so depleted that he decides not to go on to Paris. Instead, he decides to move up the coast to Calais. The French assemble a powerful army and pursue him. They surround him near the small town of Agincourt, and in Act IV, the night before the battle, knowing he is outnumbered, Henry wanders around the English camp in disguise, trying to comfort his soldiers and determine what they
