 The Crown Prince was Master-General of the Ordnance in the Burmese-Siamese War of 1808, which ended in a stalemate.His elevation to crown prince also brought his royal servants, including Maung Yit (later Gen. Maha Bandula) of Dabayin and Maung Sa (later Lord of Myawaddy) of Sagaing to prominence.Myawaddy became his longtime adviser and personal secretary ("atwinwn") until his abdication in 1837.
