On the 19th November the Eagle's crew was increased to 420 men, and she was kept cruising throughout the winter, and on the 4th January 1757 she was caught in a heavy gale off the Isle of Wight, where she had most of her sails blown out of her. On 25th May she sailed from Plymouth Sound in company with H.M.S. Medway, and a day or two afterwards they fell in with and chased a French East Indiaman, the Duc d'Aquitaine, in rather heavy weather. The Medway was leading, but when getting close, had to bring to in order to clear for action, as otherwise she would be unable to open her lee ports. Pallisser, on the other hand, was all ready, and pressed on, bringing the chase to action. After a hard set-to, lasting about three-quarters of an hour, the Frenchman struck, having lost 50 men killed and 30 wounded, whilst the Eagle lost 10 killed and 80 wounded; and the list of damages to the ship reported to the Admiralty shows that the action was sharp though short. The Medway was only able to afford assistance by firing a few raking shots, and suffered no damage except having ten men wounded by an accidental explosion of gunpowder. The masts and sails of the prize were so much damaged that she lost them all in the night; one of the masts in falling sank the Medway's cutter. It was found she had a complement of 493 men, and was armed with 50 guns. She had landed her East Indian cargo at Lisbon, and then proceeded to cruise for fourteen days on the look-out for an English convoy sailing in charge of H.M.S. Mermaid. She had succeeded in picking up one prize, an English brig, which was ransomed for 200 pounds. This was Cook's first experience of an important naval action, and Pallisser was complimented by the Lords of the Admiralty for his gallant conduct. The Duc d'Aquitaine was purchased for the Navy, and was entered under her own name as a third-rate, 64 gun ship, with a complement of 500 men.
The Eagle returned with her consort and her prize to Plymouth, and soon afterwards Cook's connection with her came to an end. According to Dr. Kippis, Mr. Walker had interested the Member for Scarborough, Mr. Osbaldiston, on the subject of Cook's promotion, but the rule was that candidates for Lieutenancy must have been employed on board a king's ship for a period of not less than six years, and an order had recently been issued that this regulation was to be strictly adhered to. Captain Pallisser therefore wrote to Mr. Osbaldiston that Cook:
"had been too short a time in the service for a commission, but that a Master's warrant might be given him, by which he would be raised to a station that he was well qualified to discharge with ability and credit."
The result of this correspondence is shown in the Eagle's muster roll, for on 27th June James Cook attended his last muster, and on the 30th he was discharged. The succeeding rolls registering "D. 30th June 1757. Solebay prefmnt."
THE MERCURY COOK.
At this point all the writers on Captain Cook have been led into error by following the lead of Dr. Kippis. Everyone (with the single exception of Lord Brougham, who by an evident slip of the pen puts him on board the Mersey) writes that he was appointed Master of H.M.S. Mercury, and that he joined the fleet of Admiral Saunders in the Gulf of St. Lawrence at the time of the capture of Quebec in that ship. From the Public Records it has been ascertained that the Mercury was not in the Gulf of St. Lawrence with Saunders, but in the latter half of 1759 was sent to New York, thence to Boston, and was at Spithead in April the following year. The same source also shows that not only was the Circumnavigator never on board the Mercury in any capacity, but in all probability he never even saw her. He is also said to have been Master's mate on the Pembroke, and Dr. Kippis has him appointed to three different ships on three consecutive days: the Grampus, but she sailed before Cook could join her; the Garland, but she was found to have a Master when Cook joined; and, lastly, the Mercury.
The explanation of this confusion as far as the Mercury is concerned (the rest was imagination) is that there was a second James Cook in the service, who was appointed Master of the Mercury under a warrant dated 15th May 1759 and entered on his duties immediately. He was with his ship at Sheerness on 12th July, at which time his namesake was before Quebec. On the return of the Mercury from Boston her Master was returned for some time as "sick on shore," and on 11th June 1760 was superseded by one John Emerton. Soon after he was appointed third lieutenant of the Gosport, his commission bearing date 1st April 1760, that is before he left the Mercury. He was with his new ship at the recapture of St. John's, Newfoundland, in 1762, with John Jervis, afterwards Lord St. Vincent, as his Captain. In 1765 he was on the Wolf on the Jamaica station, and was selected by Admiral Burnaby to carry despatches to the Governor of Yucatan. This duty he successfully carried out, and in 1796 published a pamphlet describing his adventures during the journey. On his return to England he applied to the Duke of Newcastle for the command of a cutter, and the letter is now in the British Museum, having been included in a collection in mistake for one written by his celebrated namesake. There is a certain similarity in the writing, but in the signature he writes the Christian name as Jas, whilst Captain Cook usually wrote Jams. The Mercury Cook was lieutenant of the Speedwell in 1773, and having had some property left him in Jersey he received leave of absence in August. He never rose above lieutenant, and disappears from the Navy List after July 1800.

CHAPTER 3. 1757 TO 1759. H.M.S. PEMBROKE.
Cook joined H.M.S. Solebay on the 30th July 1757 at Leith, where she was then stationed, but the date of his warrant has not been ascertained, although the Public Records and Trinity House have both been searched for the purpose. His stay was not long, for after a cruise of a few days she returned to Leith, and on 17th September Cook was superseded by John Nichols; in fact, his time on board was so short that his signature is not appended to any of the rolls.
