Nhâm Thìn War

The Nhâm Thìn War was a war fought between Yamatai and the Song Empire from 1773 to 1774.

Sông Thơm

also known as the Rice Bag Incident, was a war fought between Yamatai and the Hanthawaddy Empire in Dai Hoa, from 1773 to 1775. The decisive Yamataian victory in the war resulted in the beginnings of Yamataian colonial domination on the Songese peninsula, as well as the start of the rapid decline of the Hanthawaddy Empire and the ethnic group. The subsequent Cửulong River War in 1785 would eventually seal the fate of the Hanthawaddy Empire and lead directly to the modern domination of the peninsula by the.

Beginnings
On 17 June 1773, three Yamataian traders in the port city of Thilawa (Today Nha Trang) attempted to confront the local trade minister regarding a missing bag of rice from a delivery that they had purchased. After a series of misunderstandings, a fight broke out and 15 Yamataians were killed by the next day. Outraged, the Yamataian authorities demanded an explanation and compensation from the Hanthawaddy King, while Yamatai Imperial Navy gunboats were moved to the area, matched by Hanthawaddy troops amassing on the shoreline.

When the Hanthawaddy King did not respond by 24 July, the Yamataian commander, Admiral Imagawa Akinaga, ordered his ships to begin bombarding Nha Trang's port. The Hanthawaddy forces retaliated with cannon fire from the shore, prompting Imagawa to deploy a force of around 70 sailors to disembark as naval infantry in an attempt to sabotage the Hanthawaddy artillery that night. Led by lieutenant Inoue Toshinari, the special landing force appeared in the city at around midnight, successfully sabotaging the coastal artillery and moving further into the city. Misled into thinking the Yamataian landing force outnumbered his own, the Hanthawaddy commander ordered his troops to retreat from Nha Trang. Sporadic fighting ensued throughout the city, but by the afternoon of 25th July the city had fallen into Yamataian hands.

Though seizing the city was never Imagawa's objective, he proceeded to fortify the city with his available forces and await a Hanthawaddy counterattack while sending a report back to Yamatai to request for reinforcements and to update the government on the situation. Over the course of several weeks, the Hanthawaddy forces attempted first a naval counterattack followed by several land attacks, which were mostly unsuccessful due to the superior Yamataian firepower, though supplies were running low.

The Yamataian government finally received news of the war in late August.

Aftermath
Following the closure of the war, Yamatai retained control over Nha Trang and the surrounding areas, becoming the first direct colony established by Yamatai in the region.

The Hanthawaddy Empire lost prestige in the region, and the smaller city-states began eagerly trading with Yamatai, especially the Hanthawaddy's biggest rivals, the Phuong Empire.

In the later Cuulong River War, the Phuong Empire with Yamataian assistance defeated the Hanthawaddy Empire once and for all.
