The action of 31 January 1748 was a minor naval battle of the War of Austrian Succession between two British Royal naval ships and a French naval ship of the line. The battle ended with the capture of the French ship of the line Le Magnanime. In January 1748, Le Magnanime left Brest for the East Indies. She was partially dismasted in a storm off the coast of Ushant and while limping back to Brest, she was spotted by a British fleet under Edward Hawke. Magnanime being a new ship of less than four years old was added to the British navy under the same name.
