Count Nikolay Mikhailovich Kamensky (December 27, 1776 – May 4, 1811) was a Russian general who outlived his father, Field Marshal Mikhail Kamensky, by two years.

Nikolay and his elder brother Sergei were educated at a cadet school. In 1787, he was appointed Aide - de - camp to his father. Emperor Paul promoted him to Major General in 1799, the year when Kamensky chose to join Suvorov during the Swiss Campaign against Napoleon.

In the Battle of Austerlitz Kamensky, subordinated to Peter Bagration, lost 1,600 men and barely managed to escape alive. He distinguished himself at Eylau and was awarded the Order of Saint George in reward. Thereupon he was sent with 8,000 soldiers to relieve the siege of Danzig but failed in his objective, losing as many as 1,500 people. The following Battle of Heilsberg claimed the lives of 1,700 soldiers under his command.

By the time the Finnish War — the most brilliant campaign of his career — broke out in 1808, Kamensky had a reputation for being reckless about his soldiers' lives. However, he was promoted to Full General in 1809 and achieved important successes against the Swedes at Kuortane and Oravais. It was he who came up with a daring plan of the Russian infantry's crossing the frozen Gulf of Bothnia from Finland towards Umeå and Åland, which forced Sweden to cede Finland to Tsar Alexander.

The war in the north over, Kamensky succeeded Bagration in charge of the Danube Army, which operated against the Turks in the Russo – Turkish War (1806 – 1812). Accompanied by his elder brother, Kamensky stormed Silistra and Pazardzhik but failed to take Shumen and Rousse. On 26 October 1810 he roundly defeated a 40,000 strong army of Osman Pasha at Vidin. Russians lost only 1,500 men, compared with 10,000 for their opponents.

On February 4, 1811 Kamensky caught fever and was transported to Odessa for convalescence, leaving Louis Alexandre Andrault de Langeron in command. He died three months later at the age of 34. Kamensky is related to actress Helen Mirren, whose great - great - great - great - grandfather was his father.
