The HMS Beagle departs on its first voyage.
Captain Pringle Stokes was appointed captain of Beagle on 7 September 1825, and the ship was allocated to the surveying section of the Hydrographic Office. On 27 September 1825 Beagle docked at Woolwich to be repaired and fitted out for her new duties. Her guns were reduced from ten cannon to six and a mizzen mast was added to improve her handling, thereby changing her from a brig to a bark.
Beagle set sail from Plymouth on 22 May 1826 on her first voyage, under the command of Captain Stokes. The mission was to accompany the larger ship HMS Adventure on a hydrographic survey of Patagonia and Tierra del Fuego, under the overall command of the Australian Captain Phillip Parker King, Commander and Surveyor.
Faced with the more difficult part of the survey in the desolate waters of Tierra del Fuego, Captain Stokes fell into a deep depression. At Port Famine on the Strait of Magellan he locked himself in his cabin for 14 days, then after getting over-excited and talking of preparing for the next cruise, shot himself on 2 August 1828. Following four days of delirium Stokes recovered slightly, but then his condition deteriorated and he died on 12 August 1828. Captain Parker King then replaced Stokes with the First Lieutenant of Beagle, Lieutenant William George Skyring as commander, and both ships sailed to Montevideo. On 13 October King sailed Adventure to Rio de Janeiro for refitting and provisions. During this work Rear Admiral Sir Robert Otway, commander in chief of the South American station, arrived aboard HMS Ganges and announced his decision that Beagle was also to be brought to Montevideo for repairs, and that he intended to supersede Skyring. When Beagle arrived, Otway put the ship under the command of his aide, Flag Lieutenant Robert FitzRoy.
The 23-year-old aristocrat FitzRoy proved an able commander and meticulous surveyor. In one incident a group of Fuegians stole a ship’s boat, and FitzRoy took their families on board as hostages. Eventually he held two men, a girl and a boy, who was given the name of Jemmy Button, and these four native Fuegians were taken back with them when Beagle returned to England on 14 October 1830.
During this survey, the Beagle Channel was identified and named after the ship.
The log book from the first voyage, in Captain FitzRoy’s handwriting, was acquired at auction at Sotheby’s by the Museo Naval de la Nación located in Tigre, Buenos Aires Province, Argentina, where it is now preserved.
