Zieten was promoted to "generalleutnant" and took part in the Battle of Reichenberg in 1757 and again at the Battle of Prague. On 5 May 1757, he received the Order of the Black Eagle. In the Battle of Kolín he commanded the advance guard and was then assigned to Duke August Wilhelm Brunswick-Wolfenbüttel-Bevern, who was given the command in Silesia. On 24 November 1757, he led the rest of the army past Glogau to Liegnitz to join Frederick's army; he subsequently distinguished himself in the Battle of Leuthen on 5 December, by helping to run down the Austrian left flank. At the Battle of Hochkirch, his cavalry, and that of Seydlitz, provided the rear guard for the Prussian withdrawal. During the attack at Domstadt, he could not prevent the loss of a large supply convoy. During the Battle of Liegnitz on 15 August 1760, he managed to keep the Austrian main army at bay so that it could not participate in the battle. Zieten was promoted to general of cavalry. He made one of the few tactical mistakes of his career early in the Battle of Torgau, 3 November 1760, when he misdirected an attack against the Austrian troops; he made up for this error when he and his hussars stormed the Süptitzer heights.
