George would follow his brother Thomas, 29 years his senior, into the Royal Navy, although Thomas had drowned in an accident in 1782. Joining the Navy aged 13 in 1796, Cadogan served in the French Revolutionary Wars.
By 1807, George was a Post Captain and in 1811 he was given command of the newly commissioned HMS Havannah, a 36 gun fifth rate frigate. In 1812 HMS Havannah was ordered to the Adriatic, to reinforce the British squadron there that had already defeated the French forces in the area at several battles in 1811. HMS Havannah was based at the island of Lissa, but in 1813 Cadogan was ordered to operate against the Northern Italian coastline in conjunction with the approaching forces of the Austrian Empire during the War of the Sixth Coalition.
Cadogan was highly successful in this endeavour, destroying or capturing numerous French and Italian ships off Vasto and other ports on the French held coastline. In October 1813, Cadogan was attached to the force under Thomas Fremantle that forced the surrender of Trieste and later in the year HMS Havannah successfully captured Zara from the French garrison in a daring coastal raid.
In 1815, Cadogan returned to Britain and was made Companion of the Order of the Bath. Cadogan was married to Honoria Louisa Balke and the couple had five children, the third of whom, Henry, later became 4th Earl Cadogan and the fifth General Sir George Cadogan of the British Army.
The untimely deaths of six of Cadogan’s seven brothers brought him the title of Earl Cadogan (which his father had been awarded in 1800) on the death of his eldest brother Charles Cadogan 2nd Earl Cadogan in 1832.
Cadogan took his seat in the House of Lords, but remained a prominent naval officer, continuing to rise in the service and serving as aide de camp to William IV between 1830 and 1837 and Queen Victoria between 1837 and 1841.
By 1851, Cadogan was a vice admiral and in 1852 he became a fellow of the Society of Antiquaries of London. Cadogan died a full admiral in 1864 in his London home in Picadilly.
His youngest son Frederick William Cadogan sat as Member of Parliament for Cricklade.
