French, however, in the course of the year lost a few fortresses on the Meuse, including Grave and Huy. The king’s part in the campaign was, as usual, a war of sieges; an army under his personal command overran Franche-Comté in six weeks, and Louis, aided by the genius of Vauban, reduced Besançon in nine days. Turenne’s Rhine campaign began with an invasion of Germany, undertaken to prevent interference with Louis in Franche-Comté. Bournonville, the imperial commander who now replaced Montecucculi, lay in the Cologne and Trier electorates. An army of South Germans in the Breisgau, after an unsuccessful attempt to invade Alsace, moved northward to the Neckar valley with the intention of uniting with Bournonville, who was moving up the Rhine to meet them. Turenne determined to attack the southern army under the duke of Lorraine and Count Caprara before the junction could be effected. He crossed the Rhine at Philipsburg early in June, and on the 16th fell upon the inferior forces of Caprara in their entrenched position of Sinsheim. The result of the battle was a complete victory for the French, who followed up their success by driving a portion of Bournonville’s army (on which the duke of Lorraine had rallied his forces) from the Neckar (action of Ladenburg near Heidelberg, July 7th). Turenne then laid waste the Palatinate, in order that it should no longer support an army, and fell back over the Rhine, ignoring the reproaches of the elector palatine, who vainly challenged him to a duel. This devastation has usually been considered as a grave stain on the character of the commander who ordered it, but Turenne’s conception of duty did not differ in this respect from that of Cromwell, Marlborough, Wellington and the generals of the American Civil War. It was held to be necessary and expedient, and it was accordingly carried out. Bournonville’s army near Frankfort was still to be dealt with, and the Great Elector and his Brandenburgers were rapidly approaching the Main valley. After a slight attempt to invade Lorraine, which Turenne easily stopped, the Imperialists suddenly recrossed the Rhine and marched rapidly into the neighbourhood of the Strassburg bridge.
Turenne’s Winter Campaign in Alsace.—The magistrates of this city were not less amenable than had been the bishop of Würzburg in 1673. Bournonville obtained a free passage, and Turenne was too late to oppose him. The French general, however, determined to fight, as he had done at Sinsheim, to prevent the junction of the two hostile armies. The Great Elector was still in the Neckar valley when the battle of Enzheim (8 m. from Strassburg) was fought on the 4th of October. This time it was indecisive, and Bournonville’s superior forces, soon augmented by the arrival of the elector, spread into Alsace. Turenne steadily retired to his camp of Dettweiler, unable for the moment to do more, and the Germans took up winter quarters in all the towns from Belfort to Strassburg (October-November 1674). But Turenne was preparing for another winter campaign, the most brilliant in the great commander’s career.
First he placed the fortresses of middle Alsace in a state of defence, to deceive the enemy. Then he withdrew the whole of the field army quietly into Lorraine. Picking up on his way such reinforcements as were available, he marched southward with all speed behind the Vosges, and in the last stages of the movement he even split up his forces into many small bodies, that the enemy’s spies might be misled. After a severe march through hilly country and in the midst of snowstorms, the French reunited near Belfort, and without a moment’s delay poured into Alsace from the south. The scattered Imperialists were driven towards Strassburg, every corps which tried to resist being cut off. Bournonville stood to fight at Mülhausen with such forces as he could collect (29th December 1674) but Turenne’s men carried all before them. The advance continued to Colmar, where the elector, who was now in command of the Germans, stood on the defensive with forces equal to Turenne’s own. The battle of Türkheim (5th of January 1675) nevertheless resulted in another and this time a decisive victory for the French; a few days after the battle Turenne could report that there was not a soldier of the enemy left in Alsace. His army now went into winter quarters about Strassburg, and drew supplies from the German bank of the Rhine and even from the Neckar valley (January 1675).
1675.—This opening of the campaign promised well, and Louis as usual took the field as early as possible. In the course of the spring (May-June) the king’s army recaptured some of the lost fortresses of the Meuse and took in addition Liège and Limburg. The expeditionary corps in Sicily also gained some successes in this campaign, and Schomberg invaded Catalonia. On the Rhine was fought the last campaign of Turenne and Montecucculi. The elector having withdrawn his forces to Brandenburg (see Sweden: History), Montecucculi resumed command, and between Philipsburg and Strassburg the two great commanders manœuvred for an advantage, each seeking to cover his own country and to live upon that of the enemy. At last Turenne prevailed and had the Imperialists at a disadvantage on the Sasbach, where, in opening the action, he was killed by a cannon-shot (July 27th). The sequel showed how dependent was even the best organized army of the time upon the personality of its commander.
All the advantages won were hastily surrendered, and Montecucculi, sharply following up the retreat of the French, drove them over the Rhine and almost to the Vosges. At the same time the duke of Lorraine defeated Marshal Créqui (August 11th) at Conzer Brücke on the Moselle, and recaptured Trier (September 6th), which, as a set-off against Bonn, Turenne had taken in the autumn of 1673. The situation was more than alarming for the French, but Condé was destined to achieve a last success—for once a success of careful strategy and prudent manœuvre. Luxemburg was left in charge in Flanders, and the prince took command of the remnant of Turenne’s old army and of the fugitives of Créqui’s. Montecucculi’s skill failed completely to shake his position, and in the end the prince compelled him to retire over the Rhine. Condé and Montecucculi retired from their commands at the close of the year, Turenne was dead, and a younger generation of commanders henceforward carried on the war.
1676.—In 1676 the naval successes of France in the Mediterranean enabled the corps under Marshal Vivonne in Sicily to make considerable progress, and he won an important victory at Messina on the 25th of March. Vivonne was made viceroy of Sicily. Louis himself, with his marshals and Vauban, conducted the campaign in the north. The town of Condé fell on the 26th of April, and the king then manœuvred against the prince of Orange in the neighbourhood of Valenciennes. An attempt made by the latter in the summer to besiege Maastricht was frustrated by Marshal Schomberg with a detachment of the king’s army (August). Rochefort meanwhile covered the Meuse country and Luxemburg. Créqui, who had now returned from captivity (he had been taken after the battle of Conzer Brücke) opposed the Imperialists in Lorraine, but he was unable to prevent the fall of Philipsburg, which occurred on the 17th of September. The French now laid waste the land between the Meuse and Moselle for the same reason which brought about the devastation of the Palatinate in 1674, and the year closed with a war of manœuvre on the upper Rhine between the Imperialists under the duke of Lorraine and the French under Luxemburg.
1677.—The chief event of the campaign of 1677 in the Netherlands was the siege of Valenciennes, which fortress was invested by Louis in the first weeks of the campaigning season. Five marshals of France served under the king in this enterprise, but their advice was of less value than that of Vauban, whose plans the king followed implicitly, even so far as to order an assault de vive force against the unanimous opinion of the marshals. This succeeded beyond Vauban’s own expectation; the picked troops entrusted with the attack of an outwork forced their way into the town itself (March 17th). The success was followed by the siege of St Omer and the defeat of William’s relieving army by the duke of Orleans (battle of Mont Cassel, April 11th, 1677). The summer campaign was a contest of skill
