At the same time the duke of Lorraine defeated Marshal Crequi (August 11th) at Conzer Briicke on the Moselle, and recaptured Trier (September 6th), which, as a set-off against Bonn, Turenne had taken in the autumn of 1673.
Crequi, who had now returned from captivity (he had been taken after the battle of Conzer Briicke) opposed the Imperialists in Lorraine, but he was unable to prevent the fall of Philipsburg, which occurred on the 17th of September.
In Germany the credit of the French successes was due to Crequi, who was no longer the defeated general of Conzer Briicke, but the most successful of Turenne's pupils.
A large reinforcement sent by the duke of Lorraine to the assistance of Saxe-Eisenach was completely defeated by Crequi in the battle of Kochersberg near Strassburg (October 7th) and the marshal followed up his successes by the capture of Freiburg on the 14th of November.
On the Rhine, Crequi began by winning the battle of Rheinfelden (July 6th), after which he inflicted upon the Imperialists another defeat at Gengenbach (July 23rd) and took Kehl.
Vauban was unique amongst the officers of his time, and Crequi and Luxemburg were not unworthy successors of Turenne and Conde.
Crequi died in 1684 at the age of sixty-one, Luxemburg's greatest triumph was won ten years later (see GRAND ALLIANCE, WAR OF THE).
