Battle of Ivry
French Wars of Religion · Ivry-la-Bataille, Normandy (France)
Summary
On 14 March 1590 at Ivry-la-Bataille (Eure), Henry IV won a decisive victory over the Catholic League army of the Duke of Mayenne. With about 11,000 men against 16,000 Leaguers, the Protestant king repelled reiter and lancer charges, spoke the famous words 'Rally to my white plume,' and routed an army threatening to lift the Siege of Paris.
Historical context
On 14 March 1590 at Ivry-la-Bataille (Normandy), Henry IV faced the Catholic League army commanded by the Duke of Mayenne during the Wars of Religion. Paris, besieged by Henry for nearly a year, risked famine; Mayenne tried to relieve Dreux and deployed on the plain of Saint-André against about 8,000 royal infantry and 3,000 cavalry.
Tactics
Royal artillery of six guns opened the fight; League reiters overthrew Aumont's light horse and destroyed the royal guns. Henry IV charged the League lancers, delivered his white-plume harangue, and rallied his troops after a melee in which he was several times thought dead. Montpensier and Biron repulsed the opposite wing; German landsknechts were massacred.
Consequences
The League army was destroyed: five guns, all enemy colors, Mayenne's cornet, and Egmont's standard were captured. Mayenne fled to Nantes; Henry could continue the Siege of Paris, reinforced by arriving Spaniards. Ivry consolidated Henry IV's legitimacy and prepared his conversion to Catholicism (1593) and the Edict of Nantes (1598), ending the Wars of Religion.
