Fyodor Fyodorovich Ushakov (Russian: Фёдор Фёдорович Ушако́в) was the most illustrious Russian naval commander and admiral of the 18th century.
Ushakov was senior in rank to Nelson, and Nelson would be subordinate to him. Nelson disliked that very much, and therefore suggested dispatching the Russian squadron to Egypt instead.
Brewing conflict between the commanders was prevented by Ushakov's being recalled to Russia in 1800, where the new Emperor, Alexander I, failed to appreciate his victories. Ushakov resigned command in 1807 and withdrew into the Sanaksar Abbey in modern-day Mordovia. He was asked to command the local militia during the Patriotic War of 1812 but declined.
In the course of 43 naval battles under his command he did not lose a single ship and never lost a battle.
