Here is one new entry [#20] based on Razadarit Ayeidawpon and two entries on the king of Ava Minhkaung's brother Theiddat [#9, #17] who helps him win the throne but who is never satisfied and challenges his older brother king Minhkaung hoping to win the throne.
Ironically, after Theiddat defects to the south and Razadarit sends him on a mission to kill his brother Minhkaung, Theiddat reveals the plan and Razadarit has him executed.
I'm starting to get material out of U Kala's Burmese Chronicle to glue the whole narrative together. There's a lot of material in U Kala that fills in the gaps in Razadarit Ayeidawpon.
I have a parallel timeline for events (c. 1385-1421) from Razadarit Ayeidawpon and U Kala that I will post soon. U Kala's chronology definitely seems better. Here are the new entries:
9. Ava succession crisis in 1400: Minhkaung becomes king (UKI:462-465)
17. Theiddat challenges Minhkaung and flees to Razadarit after his defeat (c. 1406)
20. Razadarit marches north to Prome (c. 1408)
