The HMS Badger Expedition

The name Hargreaves Archipelago appeared for the first time on the charts published by the Royal Navy in 1830 . These were produced by Captain Charles Horton Hargreaves.
In 1826 the Admiralty had revealed plans for an expedition to ' the colony of Tamba- Tamba and the attendant archipelago...'
The main purpose of the expedition was to conduct a hydrographic survey of the area in order to to produce nautical charts showing navigational and sea depth information for naval war or commerce, along with drawings of the hills as seen from the sea showing measured heights of the hills.
It was also proposed to expand on the work of the Sir Surtees Gough expedition and gather more information on the island itself.
The vessel chosen was HMS Badger , a Cherokee class 10-gun brig-sloop.
The expedition , a year in the planning, was to be led by Captain Charles Horton Hargreaves RN (1798-1838).
Captain Hargreaves pulled some strings at the Admiralty to find a role for his brother, Hugh Horton Hargreaves (1801-1862) on the expedition. A keen naturalist and skilled draughtsman who saw himself as a second Sir Joseph Banks, Hugh Horton Hargreaves had studied medicine at Edinburgh before moving on to Cambridge to study marine biology. In fact, whilst at college, he had bombarded Sir Joseph Banks with letters of admiration in which he also outlined his various theories at great length.
Captain Hargreaves would concentrate on the surveying and charting whilst Hugh Horton would take more interest in the natural history of the region.
The Badger sailed from Plymouth on September 1st 1827.
