In the Battle of Leuthen, he was able to defeat and disperse the enemy outposts commanded by General von Nostitz, including two Saxon and two Austrian hussar regiments. In September 1758, he was promoted to generalmajor and awarded the Order Pour le Mérite. In October, the Habsburg General Karl Marquis de Ville laid siege to the Neisse fortress. Werner was part of the relief troops and he was able to break through Russian and Habsburg lines in the Battle of Landskrone. He then went to Kosel, which was also besieged. In the spring of 1759 he was able to drive General de Ville from Silesia. In August 1760, he was part of the relief army of Prince Henry for Dresden; on the way he defeated the Dragoon regiment "Prince Joseph". For this he received from Frederick II the appointment as a provost in the cathedral at Minden and an endowment of 2,000 thalers. He was subsequently given the command of his own corps, and sent to relieve the besieged fortress of Kolberg. He marched the from Glogau to Kolberg from 5 to 18 September and upon arrival, he surprised the Russians by attacking immediately. The Russians were routed, fled their camp in a panic, and withdrew toward Russia. For this victory, he was memorialized on a commemorative coin. Werner received gold and twenty silver coins from the King. Subsequently, though, he was less successful: on 3 October 1760 at the Battle of Pasewalk, in Vorpommern-Greifswald, his troops attempted to storm the town and, although they took many prisoners during their attack on the redoubts, when darkness fell, Werner ordered his troops to withdraw.
