Hsinbyushin

Hsinbyushin launched a massive two-pronged invasion of Siam from the north and west. The campaign aimed to subjugate the Siamese kingdom and was the largest military operation of the Konbaung dynasty, involving over 50,000 troops.

Hsinbyushin's armies captured and completely destroyed the Siamese capital of Ayutthaya after a 14-month siege. The city was burned, its treasures looted, and thousands of captives were taken to Burma. This ended the Ayutthaya kingdom.

Hsinbyushin's forces defeated a Chinese invasion army at Kaungton in northern Burma. The Qing dynasty had launched a punitive expedition to stop Burmese expansion into Siam. The Burmese victory repelled the Chinese and secured the northern border.

Hsinbyushin crushed a major rebellion by the Mon people in Lower Burma. The Mon had risen up against Konbaung rule, seeking independence. The rebellion was brutally suppressed, leading to further depopulation and destruction in the region.
