Soon after his promotion, he was sent to Germany, to collect and reorganise the French army, which had been roughly handled at Duttlingen. It wanted rest, men, and money, and he settled it in good quarters, raised recruits, and pledged his own credit for the necessary sums. The effects of his exertions were soon seen. He arrived in Alsace, December, 1643, and in the following May was at the head of 10,000 men, well armed and equipped, with whom he felt strong enough to attack the Imperial army, and raise the siege of Fribourg. At that moment the glory which he hoped and was entitled to obtain, as the reward of five months’ labour, was snatched from him by the arrival of the celebrated Prince de Condè, at that time Duc d’Enghien, to assume the command. The vexation which Turenne must have felt was increased by the difference of age, for the Prince was ten years his junior, and of personal character. Condè was ardent and impetuous, and flushed by his brilliant victory at Rocroi the year before; Turenne cool, calculating, and cautious, unwearied in preparing a certainty of success beforehand, yet prompt in striking when the decisive moment was come. The difference of their characters was exemplified upon this occasion. Merci, the Austrian commander, had taken up a strong position, which Turenne said could not be forced; but at the same time pointed out the means of turning it. Condè differed from him, and the second in command was obliged to submit. On two successive days two bloody and unsuccessful assaults were made: on the third Turenne’s advice was taken, and on the first demonstration of this change of plan Merci retreated. In the following year, ill supplied with every thing, and forced to separate his troops widely to obtain subsistence, he was attacked at Mariendal, and worsted by his old antagonist Merci. This, his first defeat, he felt severely: still he retained his position, and was again ready to meet the enemy, when he received positive orders from Mazarin to undertake nothing before the arrival of Condè. Zealous for his country and careless of personal slights, he marched without complaint under the command of his rival: and his magnanimity was rewarded at the battle of Nordlingen, in 1645, where the centre and right wing having failed in their attack, Turenne with the left wing broke the enemy’s right, and falling on his centre in flank, threw it into utter confusion. For this service he received the most cordial and ample acknowledgments from Condè, both on the field, and in his despatches to the Queen Regent. Soon after, Condè, who was wounded in the battle, resigned his command into the hands of Turenne. The following campaigns of 1646–7–8 exhibited a series of successes, by means of which he drove the Duke of Bavaria from his dominions, and reduced the Emperor to seek for peace. This was concluded at Munster in 1648, and to Turenne’s exertions the termination of the thirty years’ war is mainly to be ascribed.
