Act I, Scene i of Henry V takes place in an antechamber of the King’s palace, where two senior clergymen, the Archbishop of Canterbury and the Bishop of Ely, meet to discuss a bill that has been introduced in Parliament. This bill, which had previously been proposed during the reign of Henry IV but never passed, would strip the Church of a significant portion of its wealth and land holdings, transferring that property to the Crown. The Archbishop of Canterbury explains to the Bishop of Ely that the bill poses a serious threat to the Church, as it would deprive the clergy of a substantial amount of their temporal possessions and revenues.

The conversation then shifts to King Henry V himself, with the Archbishop speaking admiringly of the king’s remarkable transformation and his surprising depth of knowledge and wisdom. Canterbury marvels at how Henry, who in his youth was known for his wild and dissolute behavior, has grown into a learned, eloquent, and pious ruler. The Archbishop then reveals that he has offered the King a very large sum of money from the Church in support of Henry’s potential military campaign to claim the French throne, partly as a means of diverting the King’s attention away from the threatening legislation. The scene closes with the two clergymen preparing to attend upon the King, who is about to receive ambassadors from France.

Henry V follows the young English king as he transforms from the wayward Prince Hal into a decisive military leader. The play opens with Henry’s court debating his claim to the French throne through his great-great-grandmother’s lineage. When the French Dauphin mockingly sends Henry tennis balls as a gift, suggesting he should stick to games rather than warfare, Henry uses this insult as justification to invade France. He sentences three conspirators - Cambridge, Scroop, and Grey - to death for plotting against his life, then sets sail for France with his army.

The English forces land in France and lay siege to Harfleur, which Henry captures after his famous “Once more unto the breach” speech. However, his army is weakened by disease and casualties. Meanwhile, we follow the tavern companions from Henry’s youth - Pistol, Nym, Bardolph, and Hostess Quickly, who reports the death of Falstaff. The English army, vastly outnumbered, faces the French at Agincourt. On the eve of battle, Henry disguises himself and walks among his soldiers to gauge their morale, engaging in philosophical discussions about kingship and responsibility.

The Battle of Agincourt proves to be a decisive English victory despite overwhelming French numerical superiority. Henry orders the killing of French prisoners when he believes the French are regrouping, and becomes enraged when he discovers French forces have killed the English boys guarding the baggage train. The English suffer minimal casualties while French losses are enormous. The play concludes with Henry’s courtship of Princess Katherine of France, conducted partly in broken French and English. Their marriage seals the Treaty of Troyes, which names Henry as heir to the French throne, though the Chorus epilogue reminds the audience that Henry’s son would later lose these French territories.
