Franz von Mercy

Franz Freiherr von Mercy (or Merci), lord of Mandre and Collenburg (died 1645), German general in the Thirty Years' War, who came of a noble family of Lorraine, was born at Longwy some time between 1590 and 1598. From 1606 to 1630 he was engaged in the imperial service. By the latter year he had attained high military rank, and after distinguishing himself at the first Battle of Breitenfeld (1631) he commanded a regiment of foot on the Rhine and defended Rheinfelden against the Swedes with the utmost bravery, surrendering only after enduring a five-months' siege. He now became a general officer of cavalry (General-Feldwachtmeister), and in 1635, 1636 and 1637 took part in further campaigns on the Rhine and Doubs.

In September 1638 he was made master-general of ordnance in the army of Bavaria, then the second largest army in Germany. In the next campaign he was practically commander-in-chief of the Bavarians, and at times also of an allied army of Imperialists and Bavarians. He was now considered one of the foremost soldiers in Europe, and was made general field marshal in 1643 when he won his great victory over the French Marshal Rantzau at the Battle of Tuttlingen (Nov. 24-25), capturing the marshal and seven thousand men.

In the following year Mercy opposed the French armies, now under the Great Condé and the Vicomte de Turenne. He fought, and in the end lost, the desperate Battle of Freiburg, but revenged himself the next year by inflicting upon Turenne the defeat of Mergentheim (Marienthal). Later in 1645, fighting once more against Enghien and Turenne, Mercy was killed at the Battle of Nordlingen (or Allerheim) at the crisis of the engagement, which, even without Mercy's guiding hand, was almost a drawn battle. He died on 3 August 1645. On the spot where he fell, Enghien erected a memorial, with the inscription "Sta viator, heroem calcas".
