National Maritime Museum, London) In May 1793 Withers reported to the
HMS Agamemnon, which was newly-commissioned by Captain
Horatio Nelson. Withers may have had a connection with his
captain; as a boy, Nelson had attended the
grammar school at North Walsham, a few miles from the
village where Withers was born. Withers served on the
Agamemnon as a
midshipman, the ship's schoolmaster, and the
master's mate up until July 1796, when he was transferred with Nelson to the
HMS Captain. Withers' time on the
Agamemnon coincided with the
Mediterranean campaign of 1793–1796. He was landed on
Corsica at
Bastia and
Calvi, and was wounded at
Oneglia on 29 August 1795. In November of that year, he was captured at
Vado Ligure. On 15 February 1797, one day after the
Battle of Cape St. Vincent, Withers was promoted to the rank of
lieutenant into the prize-ship
Salvador del Mundo, an appointment that was confirmed a month later on 22 March. From February 1798 to December 1800 he served with Sir
Richard Hussey Bickerton on
HMS Terrible in the
English Channel. He later served with Bickerton on
HMS Kent in the Mediterranean and along the coast of Egypt. In August 1802, he was made acting commander of the Egyptian expedition, a commission that was confirmed on 11 April 1803. For a few months in the end of 1804, Withers commanded a
sloop-of-war,
HMS Tartarus, operating in the English Channel. The ship was wrecked on a sandbank off
Margate on 20 December 1804; the crew was rescued. In 1805 he was appointed as a
transport agent for the
Elbe and
Weser rivers in Germany. He continued as an agent for 11 years, serving in
Sicily, the
Ionian Islands,
Alexandria,
Halifax, and
Martinique. Between 1810 and 1816 he was the principal agent for Italy and Spain in the Mediterranean. He was made a
post-captain on 13 May 1809. ==Personal life==
