JAṬṬŪ, BHĀĪ (d. 1621), a devoted Sikh of the time of Gurū Hargobind known for his fighting skill. In the battle of Ruhelā he was despatched at the head of two hundred warriors to meet the attacking Mughal force from Jalandhar. Towards the end of the action that ensued, Bhāī Jaṭṭū challenged the commander of the enemy vanguard, Muhammad Khān, to a duel. Musket shots of both having gone astray, they, narrates Bhāī Santokh Siṅgh, Srī Gur Pratāp Sūraj Granth, took up bows and arrows. "This time the arrows from both ends found their respective targets and the two warriors fell together mortally wounded, as men from both sides looked on."
