The Battle of Ivry was fought on March 14, 1590, during the French Wars of Religion (see that article for background on the conflict). The battle was a decisive victory for Henry of Navarre, the future Henry IV of France, leading Huguenot forces against the Catholic League forces led by the Duc de Mayenne. Henry's forces were victorious and he went on to lay siege to Paris.

The battle occurred on the plain of Épieds near Ivry (later renamed Ivry-la-Bataille), Normandy. Ivry-la-Bataille is located on the Eure River and about thirty miles west of Paris, at the boundary between the Île-de-France and the Beauce regions.

[edit] The Battle of Ivry

Henry de Navarre had moved rapidly to besiege Dreux, a town controlled by the League. As Mayenne followed intending to raise the siege, Henry withdrew but stayed within sight. He deployed his army on the plain of Saint André between the towns of Nonancourt and Ivry.

The army of the Catholic League consisted of citizens led by priests and rebellious nobles, Swiss infantry under Appenzell, spearmen brought from Flanders by Philip, Count of Egmont, and the troopers of the Guise family with the Duke of Mayenne in command.

At first light on March 14, 1590, the two armies engaged. The Duke had 12,000 foot soldiers supported by an assortment of German and Swiss infantry and 4,000 cavalry, 2,000 of whom were Spanish. Henry had only 8,000 foot soldiers and 3,000 men on horseback.

The action began with a few deadly cannon volleys from the six pieces of the royal artillery, which was under the command of the master, La Guiche. The cavalry of the two sides then clashed with a dreadful force. The Duke of Mayenne followed up with the mercenary troops of the Guelders and Almaine across the open field. The mercenaries, who were mostly sympathetic to the Protestant cause, fired in the air and put their spears in rest.

Mayenne charged with such a fury that after a terrible fusillade and a struggle of a full quarter of an hour which left the field covered with dead, following the defection of his mercenaries, the opposing left flank fled and the right was pierced and gave way.

Aumont soon overcame the League's light horse and their royalist counterparts retreated under the attack of a Walloon (essentially Belgian) squadron backed up by two squadrons from the League. It was then the turn of the Maréchal d'Aumont, the Duc de Montpensier and the Baron de Biron to charge the foreign cavalry, forcing it into a retreat. Marshal de Biron, in command of the rear-guard, joined up with the king who, without stopping after his victory, had crossed the river Eure in pursuit of the enemy.

However, the decisive event took place elsewhere on the battlefield: the King charged the League's lancers, who were unable to get far enough back to use their weapons.

Mayenne was driven back, the Duke of Aumale forced to surrender, and the Count of Egmont killed. The Duke of Mayenne had lost the battle. Henry pursued the losers, many of whom surrendered for fear of falling into worse hands, their horses being in no condition to get them away from danger. The countryside was full of Leaguers and Spaniards in flight, with the king's victorious army pursuing and scattering the remnants of the larger groups that dispersed and re-gathered.

[edit] Aftermath

Henry so defeated Mayenne at Ivry that he became the only credible claimant to the throne of France. However, he was not accepted into Paris until he converted to Catholicism in 1593.
