Field Marshal Hugh Gough, 1st Viscount Gough, was a senior British Army officer. After serving as a junior officer at the seizure of the Cape of Good Hope during the French Revolutionary Wars, Gough commanded the 2nd Battalion of the 87th Regiment of Foot during the Peninsular War. After serving as commander-in-chief of the British forces in China during the First Opium War, he became Commander-in-Chief, India and led the British forces in action against the Marathas defeating them decisively at the conclusion of the Gwalior campaign and then commanded the troops that defeated the Sikhs during both the First Anglo-Sikh War and the Second Anglo-Sikh War.

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.
