Frederick's maneuvers were unsuccessful against the Russians in the bloody Battle of Zorndorf, however, and Prussian forces were crushed at Kunersdorf (1759). Like the results after the Battle of Hochkirch, though, in which the Prussians had to withdraw, the Austrian and Russian Allies did not follow up on their victory. Within the week, the Russian force began a withdrawal eastward; Austrians retreated southward.
