What happens
Henry meets the French king and court to negotiate peace. After delegating treaty details to his council, Henry woos Katherine privately, declaring his love in plain, soldier's language rather than courtly flattery. Katherine resists at first, claiming French custom forbids kissing before marriage, but Henry dismisses custom as subordinate to kings. They kiss, agree to marry, and rejoin the court, where peace is formally ratified and their union celebrated as a bond between kingdoms.
Why it matters
This scene transforms Henry from warrior-king into suitor, revealing how fully he has mastered the art of performance. His wooing of Katherine is calculated yet sincere—he claims to be a plain-speaking soldier incapable of rhetorical flourish, yet every phrase is carefully chosen to disarm her resistance. When she invokes French custom to refuse his kiss, he argues that kings transcend national law: 'we are the makers of manners, Kate.' This is not romantic sentiment but political philosophy. Henry redefines the terms of power, suggesting that sovereignty includes the right to overturn tradition itself. His marriage to Katherine becomes the physical embodiment of conquest—not through force, but through charm deployed as a weapon.
The scene's structure—private wooing followed by public ratification—demonstrates how personal desire and political necessity have become inseparable in Henry's world. His love for Katherine (whether real or performed) serves the state by uniting England and France. The formal peace treaty is signed by others while Henry and Katherine negotiate their own contract in the language of the heart. Yet even this intimacy is framed in terms of duty: Katherine will bear sons 'half French, half English' who will unite the kingdoms. By the epilogue's reminder that Henry VI lost everything his father won, we understand that this marriage, like the entire war, is temporary triumph masquerading as permanent victory. The play ends not with the security of peace, but with the knowledge that all conquest is provisional.
