Battle of Ivry - The Battle

The Battle

At first light on 14 March 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.

Before the battle, the king famously spurred his troops:

"Companions! If you today run at risk with me, I will also run at risk with you; I will be victorious or die. God is with us. Look at his and our enemies. Look at your king. Hold your ranks, I beg of you; and if the heat of battle makes you leave them, think also of rallying back: therein lies the key to victory. You will find it among those three trees that you can see over there on your right side. If you lose your ensigns, cornets or flags, do never lose sight of my panache; you will always find it on the road to honour and victory."

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.
