Field Marshal Sir George Stuart White, was an officer of the British Army. He was stationed at Peshawar during the Indian Mutiny and then fought at the Battle of Charasiab in October 1879 and at the Battle of Kandahar in September 1880 during the Second Anglo-Afghan War. For his bravery during these two battles, he was awarded the Victoria Cross. He went on to command a brigade during the Third Anglo-Burmese War in 1886 and became commander of Quetta District in 1889 in which role he led operations in the Zhob Valley and in Balochistan. He was commander of the forces in Natal at the opening of the Second Boer War and fought at the Battle of Elandslaagte in October 1899. He commanded the garrison at the siege of Ladysmith: although instructed by General Sir Redvers Buller to surrender the garrison he responded "I hold Ladysmith for the Queen" and held out for another four months before being relieved in February 1900. He finished his career as Governor of Gibraltar and then as Governor of the Royal Hospital Chelsea.

Field marshal (FM) has been the highest rank in the British Army since 1736. A five-star rank with NATO code OF-10, it is equivalent to an Admiral of the Fleet in the Royal Navy or a Marshal of the Royal Air Force in the Royal Air Force (RAF). A Field Marshal's insignia consists of two crossed batons surrounded by yellow leaves below the Tudor Crown. Like Marshals of the Royal Air Force and Admirals of the Fleet, Field Marshals traditionally remain officers for life, though on half-pay when not in an appointment or retired. The rank has been used sporadically throughout its history, and was vacant during parts of the 18th and 19th centuries. After the Second World War, it became standard practice to appoint the Chief of the Imperial General Staff to the rank on his last day in the post. Army officers occupying the post of Chief of the Defence Staff, the professional head of all the British Armed Forces, were usually promoted to the rank upon their appointment.
