A total of 1,358 Victoria Crosses have been awarded since 1856 to 1,355 men. There are several statistics related to the greatest number of VCs awarded in individual battles or wars. The greatest number of Victoria Crosses awarded for a single day was 24 for deeds performed during the Indian Mutiny on 16 November 1857, 23 for deeds at Lucknow and one by Francis David Millet Brown for action at Narnoul, south of Delhi. The greatest number won by a single unit during a single action is seven, to the 2nd/24th Foot, for the defence of Rorke's Drift, 22–23 January 1879, during the Zulu War. The greatest number won in a single conflict is 628, being for the First World War. Ishar Singh became the first Indian Sikh to receive the award. Eight of the then-twelve surviving holders of the Victoria Cross attended the 150th Anniversary service of remembrance at Westminster Abbey on 26 June 2006.
