Admiral Sir Arthur Kaye Legge KCB (25 October 1766 – 12 May 1835) was an officer of the British Royal Navy who served in three wars and commanded ships in several campaigns.
Known as a brave officer and an effective commander, Legge was given several very important postings in the latter part of his career as a rear-admiral, serving in command at Cadiz during the Peninsula War. After retirement, Legge entered royal service, and was in the procession at the funeral of King George III. A very wealthy man, Legge never married, and when he died in 1835 he left large sums of money to his domestic staff.
In July 1810, Legge was promoted to rear-admiral and the following year was appointed to be commander at Cadiz in Revenge. The Spanish port was an important position as it was the seat of the Spanish government during the Peninsular War which was raging at that time. Legge performed well in this position and returned to Britain in September 1812 to become admiral in command of the River Thames. Legge held this command, from the frigate HMS Thisbe until the end of the war in 1815.
As a member of the nobility, Legge had numerous royal contacts, and became a Groom of the Bedchamber to King George III in 1801, a position that he held in London until 1812 and afterwards at Windsor, to where the mentally unbalanced king had retreated, until the king's death in 1820. Legge later marched in the procession at George III's funeral.
By the time of his retirement, Legge had risen to vice-admiral and been made a Knight Commander of the Order of the Bath. He later became a full admiral in 1830. Legge never married, and on his death in 1835, he was reported to have left over £3,000 to his butler, £1,000 each to his groom, footman, coachman and housekeeper and other substantial amounts to his other servants. He was buried in the family vault in Lewisham.
