Overall responsibility for the survey lay with George Gauld, who reported to the British commander of the Jamaica station.  James Cook (not to be confused with James Cook the explorer of the South Pacific, Australia and New Zealand), was the Master of HMS Alarm, a fifth-rate man of war of 683 tons armed with 32 guns was employed to assist Gauld in his efforts.  James Cook was not only an accomplished seaman but he was also, in his own right a more than capable surveyor and map-maker. Cook assisted Gauld on the survey of Espiritu Santo (now Tampa Bay) and he further contributed with a partial sketch of the coast from Pensacola to beyond Tampa Bay.  He made a note on his original daft for this survey that he would have liked to have surveyed that part of the coast between Cape San Blas, where this survey finishes, and Espiritu Bay but no suitable vessel was available.  Cook's depiction of the north shore of Espiritu Bay is markedly inaccurate, partly because he did not accompany Gauld on this part of the survey.

During the 68 days Alarm had spent a total of 68 days at anchor in Espiritu Bay, while Gauld finished his survey work Cook had been confined to his quarters by the Captain as the result of a blazing row between the two of them and fourteen of the crew had died of undisclosed causes.  The ensuing court-martial proceedings, held at Port Royal on January 27th and February 5th 1776 saw Cook dismissed from the navy.  The Commander of the Jamaica station Admiral Burnaby attempted to support Cook in a letter to the lords of the Admiralty on Feb 22nd, 1776, when he offered the following citation:

'Mr Cook has been of infinite service in Surveying & taking different plans of the coast & harbours of West Florida, is a good draughtsman & a good officer, I therefore hope their Lordships will restore him, & apoint him to some ship that comes out to this station, as he knows the Coast of Florida extremely well, & will greatly contribute to the completion of the Survey of the Coast' (ADM 1/238).
