The Seven Years' War, which took place from 1756 to 1763, involved all major European powers as well as many medium and small countries, including Indian tribes. At that time, the Russian Empire supported Austria in an effort to prevent the rise of Prussia, ruled by the ambitious Frederick II. Russian troops clashed with Prussian soldiers in a bloody battle at Condorf, now the village of Sarbinovo.

The Russian army was led by General-in-Chief Wilhelm Fermor, a native of Pskov Province. In August 1758, he divided his forces into two parts: one under the command of Pyotr Rumyantsev guarded the crossing over the Oder River in Schwet, while the other besieged the fortress of Küstrin. During the siege, Frederick moved to confront the Russians, and Fermor retreated to Condorf, losing contact with part of his army. On August 25 at eight in the morning, Frederick's soldiers attacked from the rear, forcing Fermor to urgently change positions.

The Prussians initially struck the right flank but met resistance. Prussian commander Friedrich Seydlitz came to help, taking command and defeating the Russian cavalry. Due to poor visibility, Russian artillery fired on their own troops. Seydlitz attacked from all sides, capturing batteries on the right flank, but the Russians continued to defend.

On the left flank, the Prussians also faced stiff resistance and were forced to retreat. However, Seydlitz's cavalry pushed back Fermor's infantry. At that moment, Russian General Thomas Demiku launched a counterattack, capturing several batteries, and one of Frederick's battalions retreated.

It is believed that Wilhelm Fermor was wounded during the battle. After that, soldiers engaged in local skirmishes and attacks.

By morning, the exhausted sides parted ways. Fermor reported a victory to Petersburg and headed to Lindenberg. Frederick also announced a triumph back home.

In the Battle of Condorf, the Russian army lost 16,000 soldiers, while the Prussian army lost 13,800. Losing a third of his troops, Frederick II lost faith in European dominance.
