Sieges of the Hundred Years' War

The sieges fought between 1337 and 1453 during the Hundred Years' War were decisive episodes in campaigns involving Edward III of England, Henry V of England, Charles V of France, Charles VII of France, and numerous regional lords such as the Dukes of Burgundy, the Counts of Armagnac, and the Dukes of Aquitaine, producing actions at places like Calais, Orléans, Bordeaux, Rennes, and Cherbourg that shaped the course of Capetian and Plantagenet contestation.

Background and Strategic Context

The strategic context for sieges drew together dynastic claims of Edward III of England and Philip VI of France, alliances including the Pacte de Calais alignments and the Auld Alliance of Scotland which influenced operations in Gascony, Normandy, and Brittany; maritime power projection by the Royal Navy (England) and logistical constraints imposed by the Seine and Loire river systems affected relief efforts at strongpoints such as Calais and La Rochelle, while political fractures like the Civil War in France (Armagnac–Burgundian Civil War) and treaties including the Treaty of Brétigny altered garrison reliability and siege priorities.

Major Sieges by Phase

Early phase (1337–1360) featured prolonged operations including the siege and capture of Calais (1346–1347) after the Battle of Crécy and the contested sieges around Saint-Jean-d'Angély and Aiguillon during campaigns by Edward, the Black Prince and John, Duke of Normandy; mid-century (1369–1380) saw sieges in reconquest drives under Charles V of France such as operations against Poitiers-region strongholds and sieges affecting Bordeaux and Bergerac in the Gascon theater. The Lancastrian revival (1415–1429) included the famous siege efforts tied to Henry V of England at Harfleur and the contemporaneous investment of towns after Battle of Agincourt, culminating in the relief and lifting of the siege of Orléans (1428–1429) associated with Jeanne d'Arc and the coronation campaign to Reims; late-phase (1429–1453) campaigns by Charles VII of France and allies, including Arthur III, Duke of Brittany and Burgundian turnarounds after the Treaty of Arras (1435), produced sieges at Castillon and the final fall of Bordeaux that ended major English territorial control.

Siege Warfare Tactics and Technology

Siegecraft combined techniques from continental practice exemplified by Sapper operations, mining and countermine during actions at Calais and Orléans, with artillery advances such as heavy bombards and early cannon introduced from Genoa and used by technicians associated with Burgundian and French ordnance units at later sieges including Castillon; fortification adaptations like concentric curtain walls, gatehouse improvements visible in Caen and Rouen, and the use of field fortifications around rivers by commanders comparable to John Talbot, 1st Earl of Shrewsbury and Constable Arthur de Richemont altered siege durations. Logistics relied on supply convoys organized by municipal bodies of Paris and Bordeaux, mercenary companies including free companies and leaders such as Sir John Hawkwood who could garrison or ravage, while diplomacy involving the Papal court and regional treaties influenced prisoner exchanges and ransom practices during protracted investments.

Key Commanders and Forces Involved

Commanders prominent in sieges included Edward III of England, Edward the Black Prince, Henry V of England, and John Talbot, 1st Earl of Shrewsbury for the English side, while French leaders such as Charles V of France, Charles VII of France, Jeanne d'Arc, Arthur de Richemont, and constables like Bertrand du Guesclin directed reliefs and counter-sieges; Burgundian actors including Philip the Good and constabulary forces allied with Duke Philip II of Burgundy played pivotal roles in urban investments. Forces comprised royal levies raised in Lancashire and Yorkshire, Gascon contingents loyal to the Plantagenet administration at Bordeaux, Breton troops under the Dukes of Brittany, garrisoned mercenaries from Italy and the Low Countries, and naval squadrons from Flanders and Hanseatic League ports providing blockade support.

Political and Economic Impact

Sieges transformed political authority by determining control of revenue centers like Bordeaux, privilege-bearing towns such as Calais with its Calais Pale, and strategic ports including La Rochelle that affected Anglo-French trade, wool flows from Linen trade centers and customs incomes tied to the Cinque Ports system; urban devastation and occupation reshaped municipal charters in Rouen and Le Mans, influenced the bargaining posture of magnates at assemblies like the Estates General, and altered noble finances through ransoms and confiscations that fed into fiscal reforms under John II of France and later fiscal policies of Charles VII of France.

Aftermath and Legacy of the Sieges

The cumulative effect of the sieges was the evolution of fortification design leading into the Early Modern period, the decline of English continental dominion culminating after the loss of Gascony and Bordeaux in 1453, and the enhancement of centralized French royal authority under Charles VII of France aided by successes at lifted sieges such as Orléans; military practice shifted toward professionalized artillery corps, while memory of sieges persisted in chronicles by Jean Froissart and administrative records that influenced later historiography of medieval warfare and the territorial consolidation of the Kingdom of France.
