The KIO raided a bank on 5 February 1960. When armed attacks began, Kachin youths (organised by Zau Seng and Zau Tu) went underground. With a force of 100, the KIA and the Kachin Independence Council (KIC) were formed in Loi Tauk, Sin Li (Theinni) on 5 February 1961. Zau Seng became commander-in-chief, and Capt. Zau Bawk (Loveland) became a major. Base Camp 1 was built about east of the village of Sin Li, near Kutkai in northern Shan State, and a basic military course was taught on 16 March 1961.
