Henri de La Tour D'Auvergne, Vicomte de Turenne - Marshal of France

Marshal of France

The relations of the principality of Sedan to the French crown markedly influenced the earlier career of Turenne; sometimes it proved necessary to advance the soldier to conciliate the ducal family, at other times the machinations of the ducal family against Richelieu or Mazarin prevented the king's advisers from giving their full confidence to their general in the field. Moreover his steady adherence to the Protestant religion provided a further element of difficulty in Turenne's relations with the ministers. Cardinal Richelieu nevertheless entrusted him with the command in Italy in 1643 under Prince Thomas (who had changed sides in the quarrel). Turenne took Trino in a few weeks before his recall to France towards the end of the year. He gained the rank of Marshal of France (19 December 1643) and soon departed to Alsace to re-organize the "Army of Weimar" (the remnant of the late Duke Bernhard of Saxe-Weimar's troops) which had just suffered a severe defeat at Tuttlingen (November 24/25, 1643). At this time, having reached thirty-two years of age, Turenne had served under four famous commanders. The methodical prince of Orange, the fiery Bernhard, the soldierly Cardinal de la Valette and the stubborn and astute Harcourt had each contributed much to the completeness of Turenne's training, and he took the field in 1644 prepared by genius and education for the responsibilities of high command.

The work of re-organization over, Marshal Turenne began the campaign in June 1644 by crossing the Rhine at Breisach, but almost instantly an army under the Duke of Enghien (afterwards the great Condé) joined him. The Duke, as a prince of the royal house, took the chief command of the united armies of "France" and "Weimar". The four famous campaigns which followed brought to an end the Thirty Years' War. The desperately fought battle of Freiburg against Franz von Mercy's Bavarians (3, 5 and 9 August 1644) proved the chief event of the first campaign, after which the French successfully besieged Philippsburg. Before the capitulation Enghien withdrew and left Turenne in command. The marshal opened the campaign of 1645 with a strong forward movement, but Mercy surprised and defeated him at Mergentheim (Marienthal) on 2 May. Enghien again came to the front with the army of France, and Turenne's army received substantial reinforcement with the arrival of a Swedish force and of a contingent from Hesse-Kassel (or Hesse-Cassel). The Swedes soon departed, but Enghien commanded 20,000 men when he met the Bavarians in a battle even more stubbornly contested than Freiburg. The French forces killed Mercy and decisively defeated his army at Allerheim near Nördlingen (3 August 1645). Ill-health forced Enghien to retire soon afterwards, leaving Turenne for the third time left in command of the French army. Again he did not fare well against the larger forces of the imperialists, but the campaign ended with a gleam of success in his capture of Trier (Trèves).

In the following year (1646) Turenne obtained more decided successes, and, by separating the Austrians from the Bavarians, compelled Maximilian I, Elector of Bavaria to make peace (signed on 14 March 1647). In 1647 he proposed to attack the thus weakened army of the emperor, but the strategists ordered him into Flanders instead. Not only did France thus lose an opportunity, but a serious mutiny broke out amongst the Weimar troops, who had not received their pay for many months. The marshal showed great tact and firmness in his treatment of the disaffected regiments, amongst whom in the end he succeeded in restoring order with little bloodshed. He then marched into Luxembourg, but soon received orders to switch to the Rhine, for in 1648 Bavaria had returned to her Austrian alliance and had taken up arms again. Turenne and his Swedish allies made a brilliant campaign, crowned by the decisive action of Zusmarshausen (17 May). Troops subsequently wasted Bavaria with fire and sword until a second and more secure pacification was obtained. This devastation, for which many modern writers have blamed Turenne, appeared no more harsh a measure than the spirit of the times and the circumstances of the case permitted.
