At the beginning of 1962, the Chinese activity along the border increased again. On 23 October, the war began with the Chinese troops attacking with superior force. The Asaphila post, manned by Jammu and Kashmir Rifles, lost one JCO and 17 other ranks. After this, all the Indian border posts were ordered to withdraw to Taliha. It is believed that the Chinese would have occupied all the vacated posts. On 16 November, two thousand Chinese troops were found in the Gelensiniak area equipped with heavy weaponry.
