Field Marshal Sir George Pollock, 1st Baronet was a British Indian Army officer. He first saw action at the Battle of Deeg and at the Siege of Bhurtpore during the Second Anglo-Maratha War before taking part in the Anglo-Nepalese War. He also commanded the British artillery at the Battle of Prome and at Bagan during the First Anglo-Burmese War. Following a disastrous retreat from Kabul in January 1842 during the First Anglo-Afghan War, the retreating forces became stranded at the small British garrison at Jalalabad and Pollock was appointed Commander of the Force sent to relieve the garrison: he advanced through the Khyber Pass and relieved the garrison in April 1842. He then set about an unauthorised but ultimately successful mission to rescue the British hostages who had been left behind in Kabul prior to the retreat. In 1844 the Pollock Medal was created to commemorate Pollock's achievements: this medal was to be awarded to the "best cadet of the season" at the Addiscombe Military Seminary.

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.
