Mone, one of the largest Shan states controlling Nyaungshwe  and Mobye , revolted soon after the army left. Its sawbwa was a brother of the king of Lan Na . In November 1557, Bayinnaung's 23,000-strong forces reinvaded, and easily defeated Mone's forces. The sawbwa fled to Chiang Mai. Bayinnaung pursued the fugitive sawbwa, and arrived at the gates of Chiang Mai after 45 days of arduous march. The king of Lan Na surrendered without a fight on 2 April 1558. By having acquired Mone and Lan Na, Bayinnaung had unknowingly become involved in the dynastic politics of middle Tai country. The ruler of Lan Xang Setthathirath was of Lan Na royalty, and wanted to regain his home kingdom. He attacked Chiang Mai in early 1559 but was repulsed. Setthathirath would prove a thorn to Bayinnaung in years to come.
