In 1814, he was given the title Count of Nollendorf (from the German name of the town Nakléřov, now part of Petrovice in the Czech Republic) for his decisive role in this battle.

After Leipzig, Kleist blockaded the fortress of Erfurt, bringing about its surrender after which, in early 1814, he marched his troops into France, where his corps was attached to Blücher's army.

At the end of the war Kleist was promoted to the rank of General der Infanterie.

During the Hundred Days, Kleist was given command of a Prussian corps (the North German Corps) which was to operate independently from Blücher's Army of the Lower Rhine; he was therefore not involved in the battles of Ligny and Waterloo.

Two years before his death he was promoted to the rank of Generalfeldmarschall ("field marshal").
