Grigory Orlov, the grandson of a rebel in the Streltsy Uprising (1698) against Peter the Great, distinguished himself in the Battle of Zorndorf (25 August 1758), receiving three wounds. He represented an opposite to Peter's pro-Prussian sentiment, with which Catherine disagreed. By 1759, Catherine and he had become lovers; no one told Catherine's husband, the Grand Duke Peter. Catherine saw Orlov as very useful, and he became instrumental in the 28 June 1762 "coup d’état" against her husband, but she preferred to remain the dowager empress of Russia rather than marrying anyone.
