Seymour was appointed
Third Naval Lord in the
Second Peel ministry in September 1841. he became Commander-in-Chief
Pacific Station, with his flag in the third-rate
HMS Collingwood, in May 1844. Later that year the French Admiral
Abel Aubert du Petit-Thouars entered into a confrontation with Queen
Pōmare IV of
Tahiti and with the English missionary and consul
George Pritchard, expelling the consul and establishing a French protectorate over the territory in the
Franco-Tahitian War. The expulsion of the consul became known as the "Pritchard Affair", a business which Seymour handled tactfully avoiding a confrontation with the French Government who had already denounced Thouars' actions. Tensions with
United States were high as a result of the
Oregon boundary dispute and Seymour avoided inflaming this situation in discussions over fisheries. Seymour became Commander-in-Chief
North America and West Indies Station, with his flag in the third-rate
HMS Cumberland, in January 1851. and became
Commander-in-Chief, Portsmouth, with his flag in the first-rate HMS
Victory in 1856. and advanced to
Knight Grand Cross of the Order of the Bath on 18 May 1860, he was appointed
Rear-Admiral of the United Kingdom on 16 May 1863 and
Vice-Admiral of the United Kingdom on 23 September 1865. Promoted to
Admiral of the Fleet on 20 November 1866, he died of
bronchitis at his home at
Eaton Square in
London on 20 January 1870. ==Family==
