Northcote’s portrait depicts the sitter wearing the uniform of an admiral. One of the medals he is wearing represents the Knight Commander of the Honorable Military Order of Bath and the other may be the King’s gold medal awarded in 1808. In his will Seymour describes himself as “a Baronet of the United Kingdom, a Rear Admiral of the Blue Squadron of His Majesty’s Fleet and Commander in Chief of His Majesty’s Ships and Vessels on the South American Station”. Seymour’s naval career was marked by slow recognition of his achievements, something that is not evident from the impressive titles he held by the time of his death.
