ĀLAM SIṄGH NACHNĀ (d. 1705), a warrior in the retinue of Gurū Gobind Siṅgh, was the son of Bhāī Durgū, a Rājpūt Sikh of Siālkoṭ. He earned the popular epithet Nachnā (lit. dancer) because of his uncommon agility. Sarūp Dās Bhallā, Mahimā Prakāsh, describes him as one of Gurū Gobind Siṅgh's constant companions. Possessing pluck as well as skill, he once killed a tiger single-handed. On another occasion when during the chase Gurū Gobind Siṅgh was suddenly attacked by two hill chiefs, Balīā Chand and Ālam Chand, with a force far outnumbering his own, Ālam Siṅgh Nachnā showed exemplary courage. In a face to face encounter with Ālam Chand, he slashed the latter's sword arm. He took part in almost all the battles fought around Anandpur. As Gurū Gobind Siṅgh himself testifies in his Bachitra Nāṭak, when Khānzādā, the son of Dilāwar Khān, Sūbahdār of Lahore, tried to storm Anandpur at night, it was Ālam Siṅgh's vigilance which alerted the Sikhs and forced the Khānzādā to retire without attempting the assault. During the final siege of Anandpur, Ālam Siṅgh was given the command of a 500 strong garrison in Agampur Fort; on the evacuation of the town, he along with Bhāī Dayā Siṅgh and Bhāī Ude Siṅgh led the vanguard. At Chamkaur on 7 December 1705, Ālam Siṅgh Nachnā joined the sally made by Sāhibzādā Ajīt Siṅgh and fell fighting the besieging host.
