Siamese support. Chiang Mai fell on 15 January 1775. Hsinbyushin on his deathbed ordered his last invasion of Siam in 1775. The Siamese defenses held this time. The Burmese armies were bogged down in central Siam in June 1776 when they withdrew after the news of Hsinbyushin's death had reached the front. Lan Na was firmly on the Siamese camp. The over two centuries Burmese rule of Lan Na had come to an end. Analysis The war came near the peak of Konbaung military power. (Their victory over the Chinese is considered the peak). According to Lieberman, the "near simultaneous victories over Siam (1767) and China (1765–1769) testified to a truly astonishing elan unmatched since Bayinnaung." To be sure, it was not so much that the Burmese had more troops or superior weapons; they did not. The main reason for Burmese victory was the same as that in the 1760 war: the Burmese, who had been in successive wars since 1740, simply had experienced, proven, confident commanders, while most Siamese commanders had little battlefield experience except in the 1760 war. It was the Burmese commanders' ability to lead a multi-ethnic army which consisted of regiments from various parts of the empire that made the invasion even possible. (Upper Burma, the home of Konbaung dynasty, alone could not have launched an offensive war against a more populous Siam without its policy of having the conquered lands contribute to its next war effort). In this war, the Burmese command was able to inspire (or push) their troops. Historian Harvey writes: "When roused, the men fought with spirit, vying among themselves as to who should first mount the wall" although he wonders why: "They died like flies from preventable disease, and suffered ghastly wounds for which they received no thanks from the King, as the loss of a limb, even in honorable service, disqualified a man from entering the palace: His Majesty's sight must not be sullied by reality." Equally important, the Burmese commanders were able to motivate their Siamese levies, which by the battle of Ayutthaya made up a significant minority of the Burmese army. The Siamese participation in the Burmese army highlights the fact that the war was between the rulers, not between nations. On the other hand, despite having made extensive preparations, when actual war came, Siamese commanders proved listless and uncoordinated. In all, they appeared to have relied much
