Baba Deep Singh (26 January 1682 – 13 November 1757) is revered among Sikhs as one of the most hallowed martyrs in Sikhism. He is remembered for his sacrifice and devotion to the teachings of the Sikh Gurus. Baba Deep Singh was the first head of Misl Shaheedan Tarna Dal – an order of the Khalsa military established by Nawab Kapur Singh, the then head of Sharomani Panth Akali Buddha Dal. The Damdami Taksal also state that he was the first head of their order. Baba Deep Singh was born on 26 January 1682 to his father Bhagta, and his mother Jioni. He lived in the village of Pahuwind in Amritsar district. He was born into a Sandhu Jat Sikh family. He went to Anandpur Sahib on the day of Vaisakhi in 1700, where he was baptised into Khalsa by Guru Gobind Singh, through the Khande di Pahul or Amrit Sanchar (ceremonial initiation into Khalsa). As a youth, he spent considerable time in close companionship of Guru Gobind Singh Ji, learning weaponry, riding and other martial skills. From Bhai Mani Singh, he learnt reading and writing Gurmukhi and the interpretation of the Gurus' words. After spending two years at Anandpur, he returned to his village in 1702, before he was summoned by Guru Gobind Singh Ji at Talwandi Sabo in 1705, where he helped Bhai Mani Singh in making copies of the scripture Guru Granth Sahib.Baba Deep Singh had vowed to avenge the desecration of the Golden Temple by the Afghan army. In 1757, he led an army to defend the Golden Temple. The Sikhs and the Afghans clashed in the Battle of Amritsar on 13 November 1757,and in the ensuing conflict Baba Deep Singh was decapitated.
