CHATAR SIṄGH, a Brāṛ Jaṭṭ, was, according to Sarūp Siṅgh Kaushish, Gurū kīāṅ Sākhīāṅ, a Sikh spy who, during the siege of Anandpur by the hill rājās in September-October 1700, used to mix with the enemy and bring intelligence about their strength, dispositions and plans. It was he who carried to Gurū Gobind Siṅgh the news one evening how Rājā Kesarī Chand, one of the besieging chieftains, had planned to smash the gate of the Lohgaṛh Fort on the following morning with the help of a drunken war-elephant.
