The invasion of the Shan country began in January 1557. (The armies left their Ava base between 24 December 1556 and 8 January 1557.) The massive show of force worked. States submitted one after another with minimal resistance. By March 1557, Bayinnaung in one stroke controlled most of the cis-Salween Shan states from the Patkai range at the Assamese border in the northwest to Mohnyin (Mong Yang), Mogaung (Mong Kawng) in present-day Kachin State to Momeik (Mong Mit), and Thibaw (Hsipaw) in the northeast. But order broke down right after the army left. The powerful state of Mone (Mong Nai), which sent in tribute in 1556 and thus did not face the invasion, revolted with the support of Lan Na, which was ruled by Mekuti, a brother of Mone's ruler. Mone forces went on to occupy Thibaw, and executed the new saopha appointed by Bayinnaung. In November 1557, five Toungoo armies (33,000 men, 1800 horses, 170 elephants) led by the king himself invaded, and easily occupied Mone and Thibaw.
