Myinzaing hatched a plan to capture Mandalay by launching a full-scale attack on the city in May 1886. 300 swordsmen and 100 musketeers would attack the police station and destroy the telegraph wires. Anaukwindawhmu U Paung would lead 200 swordsmen and 1500 Shan and Burmese musketeers to attack the city directly and slaughter Burmese ministers and officials who had capitulated under the British. Maung Gyi, Myinzaing's maternal uncle, will take on Mandalay Hill and the northern suburbs with 100 swordsmen and 700 Shan and Burmese musketeers. Mongnai Sawbwa would invade the eastern suburbs and capture Yankin Hill with 300 swordsmen and 1000 Shan and Burmese musketeers. Lawksawk Sawbwa would invade Amarapura with 250 swordsmen and 700 Shan and Burmese musketeers. Myaukdawebo Maung Gale would then administer the oath of allegiance to all Sawbwas and Myosas. Nevertheless, Myinzaing's plan could not be carried out as the British were able to uncover the activities of Myinzaing's lieutenants, putting a stop to the plan. Four other monks namely U Dipa, U Ottama, U Nandiya and U Rewata were also arrested and detained at Akyab and Rangoon. In the end, Myinzaing was forced to retreat into the Myelat State of Ywangan. He contracted fever there in August 1886 and died soon after.
