thumb|left|A print of Act III, Scene i: "Once more unto the breach, dear friends!" In Act III, Henry and his troops besiege the French port of Harfleur after crossing the English Channel. The French king, says the Chorus, "doth offer him / Katharine his daughter, and with her, to dowry, / Some petty and unprofitable dukedoms", but Henry is not satisfied. 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 hard-won battle, the English take Harfleur. Montjoy, herald of the French king Charles, delivers a message of Charles's taunts and threats, scorning Henry. Henry tells Montjoy that his forces have been so weakened that he will not yet attack Paris directly, but will instead march up the coast to Calais.
