Eugene Sweny, ‘druggist’ of Mary St. Dublin, married Elizabeth Halpen in 1777. They had three sons; the first two served in the armed forces. I am descended from the third son, Eugene jnr., a civilian.
The second son, Mark Halpen Sweny, was baptised on 11 Nov.1783 at St.Mary’s, Dublin. He served on at least nineteen ships during his naval career- Formidable, Castor, Barfleur, Donegal, Neptune, Renown, Colossus, Sparrow, St. Alban’s, Aquilon, Elephant, Benbow, Africa, Northumberland, Severn, Gannet, Vernon, President and Serpent.
On 5 June 1798, aged 14, he entered the Royal Navy as a first class volunteer on board the Formidable, serving with the Channel Fleet. The following year, on 23.2.1799, Sweny became a midshipman, or master’s mate, and served on the Castor where he was ‘severely wounded while fitting at Plymouth’.
Like his elder brother, he saw action in the Napoleonic wars. He served as acting lieutenant on the Colossus at the Battle of Trafalgar in 1805, where he was again seriously wounded. Sweny was promoted to lieutenant on 22.1.1806, commander in 1821, and captain in 1838.
Sweny was on HMS Africa in 1808 where he was wounded again during the subsequent action against the Danish flotilla in the Malmö Channel.
Sweny left the Africa, and took part in an action in China on the St. Alban’s in 1809, under Capt. F. W. Austen (Jane’s brother). It is said that he was wounded and lost one or two fingers in the action off Malmö. He was later called ‘Three Finger Jack’. In 1816 he was awarded a pension for his wounds of £91.5s. annually.
After the fall of Paris in March 1814, Napoleon went into exile on the Mediterranean island of Elba, but he escaped, returned to France and formed a new army. His last attempt at military victory ended at Waterloo on 18 June 1815. A month later, he gave himself up to the British.
This time he was exiled to a much more secure place, the island of St. Helena in the Atlantic. It was so remote that the voyage there took ten weeks. Mark Sweny was the senior lieutenant on the ship which carried him there, the Northumberland.
When Napoleon saw him, he claimed that they had met before, but it turned out that he was confusing him with his brother John, whom he had met at Waterloo. Napoleon is said to have commented, ‘He was my prisoner. And now I am yours.’
It seems that Sweny returned to Ireland for a short time before settling in England- see #79.
Sweny is mentioned in ‘Diaries of a Lady of Quality’ (1797-1844) by Miss Frances Williams Wynn, who had met him at a ball in Hastings in 1822. She calls him Captain Sweeney, so she was probably writing from her notes after 1838, when he had been promoted. He gave her an account of his dealings with the famous prisoner during the long voyage. She reports one exchange Sweny had with Napoleon:
One day he was sitting on deck in rain such as I am told can scarcely be conceived by those who have not felt tropical rains: Bertrand, Montholon, and Lascasas were all standing round him bareheaded.
My informant spoke to them, and especially to Lascasas, who has very delicate health, telling them they would make themselves ill if they did not put on their hats: they did not answer, and Buonaparte gave him a very angry look, but said nothing. He then said, 'General, you had better send for a cloak; you'll be wetted to the skin'. He very sternly replied, 'I am not made of sugar or salt.'
