remaining Burman troops to come over to him. Many did. Konbaung invasion of Lower Burma (1755–1757) While the Hanthawaddy leadership alienated their Burman constituency in the south, Alaungpaya gathered troops from all over Upper Burma, including Shan, Kachin and Chin levies. By January 1755, he was ready to launch a full-scale invasion of the south. The invading army now had a considerable manpower advantage. Hanthawaddy troops still had better firearms and modern weaponry. (Hanthawaddy's firearm advantage would claim many Konbaung casualties in upcoming battles.) Battle of Prome (June 1754 – February 1755) Alaungpaya's first target was Prome that had been under siege by the Hanthawaddy troops for seven months. The Hanthawaddy troops were well entrenched in their earthwork stockades surrounding Prome. They had repulsed Konbaung troops trying to relieve the siege throughout 1754. In January, Alaungpaya himself returned with a large army. Still, Konbaung assaults could not make any headway amid heavy musket fire by determined Hanthawaddy defenses. Alaungpaya then ordered large by basket cases filled with hay, which were to be used as cover. Then in mid-February, the Konbaung troops forced their way in behind rolling baskets amid heavy slaughter by musket fire, and captured the Mayanbin fort, relieving the siege. They captured many muskets, cannon and ammunition, which Hanthawaddy had acquired from Europeans at Thanlyin, along with 5000 prisoners of war. The Hanthawaddy troops retreated to the delta. Alaungpaya entered Prome, returned solemn thanks at the Shwesandaw Pagoda, and received homage of central Burma. He held an investiture, honoring those who had led the uprising against Hanthawaddy. Battle of Irrawaddy delta (April–May 1755) In early April, he launched the invasion of Irrawaddy Delta in a blitz. He occupied Lunhse, renaming it Myanaung (Speedy Victory). Moving down the river, the advance guard defeated the Hanthawaddy resistance at Hinthada, and captured Danubyu by mid-April, right before the Burmese new year festivities. By late April, his forces had overrun the entire delta. Alaungpaya now received homage from local lords, as far away as Thandwe in Arakan (Rakhine). Then the Konbaung armies turned their sights on the main port city of Syriam (Thanlyin), which stood in their way to Pegu. On 5 May 1755, Konbaung troops defeated a Hanthawaddy division at Dagon, on the opposite bank of Syriam. Alaungpaya envisioned Dagon to be the future port city, added settlements around Dagon and renamed the new city, Yangon (lit. "End of Strife"). Battle
