HMS Endeavour - Purchase and Refit By Admiralty

Purchase and Refit By Admiralty

On 16 February 1768, the Royal Society petitioned King George III to finance a scientific expedition to the Pacific to study and observe the 1769 transit of Venus across the sun. Royal approval was granted for the expedition, and the Admiralty elected to combine the scientific voyage with a confidential mission to search the south Pacific for signs of the postulated continent Terra Australis Incognita (or "unknown southern land").

The Royal Society suggested command be given to Scottish geographer Alexander Dalrymple, whose acceptance was conditional on a brevet commission as a captain in the Royal Navy. However, First Lord of the Admiralty Edward Hawke refused, going so far as to say he would rather cut off his right hand than give command of a Navy vessel to someone not educated as a seaman. In refusing Dalrymple's command, Hawke was influenced by previous insubordination aboard the sloop HMS Paramour in 1698, when naval officers had refused to take orders from civilian commander Dr. Edmond Halley. The impasse was broken when the Admiralty proposed James Cook, a naval officer with a background in mathematics and cartography. Acceptable to both parties, Cook was promoted to Lieutenant and named as commander of the expedition.

On 27 May 1768, Cook took command of the Earl of Pembroke, valued in March at £2,307. 5s. 6d. but ultimately purchased for £2,840. 10s. 11d. and assigned for use in the Society's expedition. She was refitted at Deptford on the River Thames for the sum of £2,294, almost the price of the ship itself. The hull was sheathed and caulked to protect against shipworm, and a third internal deck installed to provide cabins, a powder magazine and storerooms. The new cabins provided around 2 square metres (22 sq ft) of floorspace apiece and were allocated to Cook and the Royal Society representatives: naturalist Joseph Banks, Banks' assistants Daniel Solander and Herman Spöring, astronomer Charles Green, and artists Sydney Parkinson and Alexander Buchan. These cabins encircled the officer′s mess. The Great Cabin at the rear of the deck was designed as a workroom for Cook and the Royal Society. On the rear lower deck, cabins facing on to the mate's mess were assigned to Lieutenants Zachary Hicks and John Gore, ship's surgeon William Monkhouse, the gunner Stephen Forwood, ship's master Robert Molyneux, and the captain's clerk Richard Orton. The adjoining open mess deck provided sleeping and living quarters for the marines and crew, and additional storage space.

A longboat, pinnace and yawl were provided as ship's boats, though the longboat was rotten and had to be rebuilt and painted with white lead before it could be brought aboard. These were accompanied by two privately owned skiffs, one belonging to the boatswain John Gathrey, and the other to Banks. The ship was also equipped with a set of 28 ft (8.5 m) sweeps to allow her to be rowed forward if becalmed or demasted. The refitted vessel was commissioned as His Majesty's Bark the Endeavour, to distinguish her from another Endeavour already commissioned in the Royal Navy, a 14-gun sloop.

On 21 July 1768, Endeavour sailed to Galleon's Reach to take on armaments to protect her against potentially hostile Pacific island natives. Ten 4-pounder cannons were brought aboard, six of which were mounted on the upper deck and the remainder stowed in the hold. Twelve swivel guns were also supplied, and fixed to posts along the quarterdeck, sides and bow. The ship departed for Plymouth on 30 July, for provisioning and to board her crew of 85, including 12 Royal Marines. Cook also ordered that twelve tons of pig iron be brought on board as sailing ballast.
