Yes, sorry Charley, USS President, captured 15 January 1815 one day out from New York. HMS Endymion was armed with 24pdr long guns (but not has heavily armed as President). Endymion was built to the lines of the captured La Pomone (1795-7), as were 5 hurriedly-built sister ships in 1814.

If you compare Commodore Decatur's account with that of the log-book of Endymion you will find a number of discrepancies. Most American accounts rely on the evidence given by Commodore Decatur at his Court of Inquiry, which considered that the Endymion was 'subdued'. But when the next frigate arrived President surrendered promptly. Endymion could not pursue until she had spent an our replacing sails.

So what is the truth of this action? Endymion had 25 casualties (from 346), President had 105 (from 477), as well has at least five guns dismounted and six feet of water in the hold. President lost all her masts in a gale two days later and was taken (with difficulty) back to Britain. American accounts will tell you how President defeated Pomone but had to surrender to a superior squadron.

President was broken up in 1818 - she was too shattered to be put into service - and the same year a 'copy' - HMS President - was built for the Royal Navy. This later served as a training ship at London. The name was transferred to the former world war one corvette HMS Saxifrage, and is now a conference centre.
