Lan Xang was not the only remote, mountainous region the Burmese king had trouble controlling. The northernmost Shan states of Mohnyin and Mogaung (and their vassals in present-day Kachin State and Sagaing Region) collectively revolted in July 1571. He sent two 12,000-strong armies led by Nanda and Thado Dhamma Yaza II. The armies easily recaptured the states. But, like in Lan Xang, the troops spent five punishing months fruitlessly chasing after the renegade "saophas" in the snow-clad foothills of the Himalayas.
