Normandy

Overview

Normandy is the French duchy targeted by Henry V through an unsuccessful 1415 attempt to use Harfleur as a rapid springboard and a systematic conquest beginning in 1417.

Current Profile

In 1415 Henry selected Harfleur as a vulnerable port from which a wider recovery of Normandy might proceed. The siege lasted too long, damaged the intended base, and weakened his army, leaving the campaign without the time and strength required for immediate territorial expansion.

Henry returned in 1417, invoking Normandy’s association with William the Conqueror while conducting a systematic campaign. Caen, Falaise, and other positions fell before the long siege of Rouen.

Rouen’s capture in January 1419 gave England control of a major city and access along the Seine, turning Henry’s claim into territorial government and bringing direct pressure toward Paris.

Key Characteristics

• Former duchy invoked through its connection to the Norman Conquest of England.
• Intended target of a rapid 1415 campaign whose Harfleur siege consumed its opportunity.
• Principal target of Henry’s 1417 invasion.
• Territory acquired through sieges and town-by-town conquest.
• Strategic corridor whose control threatened Paris through the Seine.

Evidence

• Failed 1415 springboard: 488. Hundred Years’ War: The Road to Agincourt (Part 2) presents Harfleur as Henry’s first objective and potential base, then shows siege delay and damage frustrating the wider plan.
• Historical framing: 490. Hundred Years’ War: England Triumphant (Part 4) says Henry emphasized Normandy’s link to William the Conqueror.
• Campaign sequence: 490. Hundred Years’ War: England Triumphant (Part 4) records Caen, Falaise, and the siege of Rouen.
• Strategic value: 490. Hundred Years’ War: England Triumphant (Part 4) links Rouen to control of Seine access and pressure on Paris.

Qualifications

The sources focus on military and dynastic strategy rather than Norman civilian society or the full administrative settlement. Harfleur’s strategic role is presented as an intended springboard, not proof that a wider 1415 conquest was operationally achievable. Historical association alone did not establish legitimacy.

What Changed

• Added the failed 1415 Harfleur springboard before the successful 1417-1419 conquest.

Relationships

• England - conquering kingdom under Henry V in this source.
• France - kingdom containing the contested duchy.
• Henry V of England - ruler who made Normandy his post-Agincourt objective.
• Harfleur - port intended to open Normandy but captured too slowly for the 1415 plan.
• Hundred Years’ War - wider conflict in which Normandy became an English base.
• Norman Hybrid Identity - earlier cultural formation distinct from Henry’s later conquest claim.
