In March 1754, Hanthawaddy did what they should have done two years before, and sent the entire army. It would have been 1751-1752 all over again except that they had to face Alaungpaya instead of an effete dynasty. At first, the invasion went as planned. The Hanthawaddy forces led by Upayaza, the heir-apparent and Gen. Talaban defeated the Konbaung armies led by Alaungpaya's sons Naungdawgyi and Hsinbyushin at Myingyan. One Hanthawaddy army chased Hsinbyushin to Ava, and laid siege to the city. Another army chased Naungdawgyi's army, advancing as far as Kyaukmyaung a few miles from Shwebo, where Alaungpaya was residing. The Hanthawaddy flotilla had complete control of the entire Irrawaddy River. But they could not make further progress. They met heavy Konbaung resistance at Kyaukmyaung, and lost many men trying to take a heavily fortified Ava. Two months into the invasion, the invasion was going nowhere. The Hanthawaddy forces had lost many men and boats, and were short on ammunition and supplies. In May, Alaungpaya personally led his armies  in the Konbaung counterattack, and pushed back the invaders to Sagaing, on the west bank of the Irrawaddy, opposite Ava. On the east bank, Hsinbyushin also broke the siege of Ava. With the rainy season just a few weeks away, the Hanthawaddy command decided to retreat. Meanwhile, Burman refugees who had escaped general slaughter by the delta Mons seized Prome , the historical border town between Upper Burma and Lower Burma, and shut the gates to the retreating Hanthawaddy armies. Knowing the importance of Prome for the safety of his kingdom, King Binnya Dala of Hanthawaddy ordered his forces to retake Prome at any cost. Led by Talaban, the Hanthawady forces consisted of 10,000 men and 200 war boats laid siege to Prome.
