James Weddell had been three years on half naval pay when, in 1819, he accepted command of the Jane, a Leith brig of 160 tons, owned by a Mr. Strachan. She was intended for a sealing voyage in the Southern seas, for which the newly discovered South Shetland Islands seemed to offer great facilities.
This voyage was made in the years 1819-1821, but no record of it is extant. However although Weddell had had no previous experience as a sealer, the voyage was sufficiently successful to enable him to buy a half-share in the brig, and to be entrusted with the command for a second voyage, in company with the cutter Beaufoy, of 65 tons, of London. With these two small vessels he sailed from the Downs on September 9, 1822.
In his search for seals he examined the Falkland Islands, Cape Horn and its neighbourhood, South Georgia, the South Orkneys, which he had discovered in his former voyage, and finding the sea open, pushed on to the southward as far as latitude 74 deg. 15 mins S. which he reached on Feb 2, 1823. He returned to England in July, 1824. The voyage was then and for long afterwards the furthest southern latitude reached. The Weddell Sea is his lasting commemoration of it.
This next description is from the BAT philatelic bureau.
Weddell sailed the Jane and Beaufoy southerly from the South Orkney Islands and in a season remarkably clear of pack ice penetrated almost to the edge of the Antarctic Continent. The stamp design shows his ships at their most southerly point, with little to prevent his going further. Wisely, Weddell turned north before the season changed!
