Admiral Sir George Cranfield Berkeley GCB (10 August 1753 – 25 February 1818), often known as George Berkeley, was a highly experienced, popular, yet controversial naval officer and politician in late eighteenth and early nineteenth century Britain. Serving on several ships, Cranfield-Berkeley saw action at all three Battles of Ushant, commanded fleets in the West Indies and off Ireland and governed the supply routes to Portugal and Spain which kept Wellington's armies in the field during the Peninsula War. He also enjoyed an extensive political career, reforming military practices in Britain and participating in several prominent scandals including feuds with Charles James Fox and Hugh Palliser.
