# Ava–Hanthawaddy War (1401–1403) orders of battle

This is a list of orders of battle for the Second Ava–Hanthawaddy War in which the Royal Ava Armed Forces defended an invasion by the Royal Hanthawaddy Armed Forces between 1401 and 1403.

## Background
### Sources

The orders of battles for Ava in this article are sourced from the main royal chronicles—the Maha Yazawin, the Yazawin Thit and the Hmannan Yazawin, which primarily narrate the war from the Ava side. The orders of battle for Hanthawaddy Pegu are mainly sourced from Nai Pan Hla's version of the Razadarit Ayedawbon, which has incorporated narratives of the Pak Lat Chronicles.

### Adjustment of strength figures

The military strength figures in this article have been reduced by an order of magnitude from those reported in the chronicles, following G.E. Harvey's and Victor Lieberman's analyses of Burmese chronicles' military strength figures in general.

## Invasion of Ava (1401–1402)

Circa 15 November 1401, Hanthawaddy forces led by King Razadarit invaded Ava by land and by river.

### Hanthawaddy Pegu

The Razadarit Ayedawbon chronicle provides the most detailed description of Pegu's order of battle: (1) a naval invasion force (~5000 to 7000 troops) that sailed up to Ava, (2) a 3000-strong army that laid siege to Prome (Pyay), and (3) an army of unknown strength that guarded the capital Pegu (Bago). The main royal chronicles provide higher figures, ranging from 6000 troops and 500 war boats (Yazawin Thit) to 16,000 troops and 300 war boats (Maha Yazawin and Hmannan Yazawin).
Pegu Order of Battle, 1401–1402 :

### Ava

The Maha Yazawin chronicle (1724) names 12 forts along the Irrawaddy river to face the invasion forces. The Yazawin Thit (1798) mentions only Prome, Ava, Myede, and Pagan in its narrative, and the Hmannan Yazawin (1832) repeats the Maha Yazawin's account.
Ava Order of Battle, 1401–1402 :
| Unit | Commander | Strength | Theater |
| Royal Ava Armed Forces | King Minkhaung I | 12+ regiments | |
| Prome Regiment | Letya Pyanchi of Prome | including battalions from Gu-Htut, Hlaing and Tharrawaddy | Prome region |
| Myede Regiment | Lord of Myede | | Myede |
| Sagu Regiment | Theinkhathu II of Sagu | | Sagu |
| Salin Regiment | Nawrahta of Salin | | Salin |
| Pakhan Nge Regiment | Lord of Pakhan Nge | | Pakhan Nge |
| Sale Regiment | Lord of Sale | | Sale |
| Pagan Regiment | Uzana of Pagan | | Pagan (Bagan) |
| Talok Regiment | Yazathu of Talok | | Talok |
| Pakhan Gyi Regiment | Tarabya I of Pakhan | | Pakhan Gyi |
| Sagaing Regiment | Prince Theiddat | | Sagaing |
| Singu Regiment | Baya Gamani of Singu | | Singu |
| Capital Defense Corps | Minkhaung I | Unspecified numbers of infantry, cavalry and war elephants | Ava capital region |
Furthermore, the Ava court claimed that the kingdom's defensive network included over 50 fortified towns whose rulers were loyal to Minkhaung. According to Michael Aung-Thwin, the forts were "strategically arranged throughout the kingdom so that each town was within one day's or two days' march of another." The following are the lists reported in the three main chronicles.
Ava's fortified towns and cities, 1401–1402 :
| Chronicle | Total | Along the Irrawaddy | Southern Division | Northern Division |

Of the 17 Southern Division fortifications reported in the Maha Yazawin, at least twelve are located in the Ava capital region, not in the south. Indeed, the Yazawin Thit omits the twelve and reports only five in the Southern Division. Furthermore, it omits the Ngasingu fort, and keeps just the nearby Singu fort in the Irrawaddy Division. The Hmannan Yazawin largely follows the Maha Yazawin's list, excluding the fort at Pin, while keeping the nearby Natmauk fort. Note that Michael Aung-Thwin gives a total of 53 forts, citing the Maha Yazawin, even though it is the Hmannan's list that sums up to 53.

## Battle of Sale (April 1402)

Chronicles do provide little information with regard to the units involved. The Razadarit Ayedawbon mentions Smin Upakaung the Younger as a cavalry commander in the Hanthawaddy detachment from the retreating Hanthawaddy navy that tried to raid Sale. The main chronicles say two cavalry battalions sent down from Ava defended the town.

None of the main royal chronicles provides a specific order battle for Ava, except to say that the army included regiments from the Shan states. According to the Razadarit Ayedawbon and Yazawin Thit chronicles, the remnants of the Vanguard Army defeated in the battle of Thaymathauk also joined the main army.
