Martyrs' Day (, ) is a Burmese national holiday observed on 19 July to commemorate Gen. Aung San and seven other leaders of the pre-independence interim government, and one bodyguard —Thakin Mya, Ba Cho, Abdul Razak, Ba Win, Mahn Ba Khaing, Sao San Tun, Ohn Maung and Ko Htwe—all of whom were assassinated on that day in 1947. It is customary for high-ranking government officials to visit the Martyrs' Mausoleum in Yangon in the morning of that day to pay respects. Myoma U Than Kywe led the ceremony of the First Burmese Martyrs' Day on 20 July 1947 in Rangoon. History On 19 July 1947, at approximately 10:37 a.m., BST, several of Burma's independence leaders were gunned down by a group of armed men in uniform while they were holding a cabinet meeting at the Secretariat in downtown Yangon. The assassinations were planned by a rival political group, and the leader and alleged mastermind of that group Galon U Saw, together with the perpetrators, were tried and convicted by a special tribunal presided by Kyaw Myint with two other Barristers-at-law, Aung Thar Gyaw and Si Bu. In a judgment given on 30 December 1947 the tribunal sentenced U Saw and a few others to death and the rest were given prison sentences. Appeals to the High Court of Burma by U Saw and his accomplices were rejected on 8 March 1948. In a judgment written by Supreme Court Justice E Maung (1898–1977) on 27 April 1948, the Supreme Court refused leave to appeal against the original judgment. All the judgments of the tribunal, the High Court, and the Supreme Court were written in English. Then-President of Burma Sao Shwe Thaik refused to pardon or commute the sentences of most of those who were sentenced to death, and U Saw was hanged inside Rangoon's Insein jail on 8 May 1948. A number of perpetrators met the same fate, while minor players, who were sentenced to various terms of imprisonment, also spent several years in prison. The assassinated were: Aung San, Prime Minister Ba Cho, Minister of Information Mahn Ba Khaing, Minister of Industry and Labor Ba Win, Minister of Trade Thakin Mya, Minister Without Portfolio, unofficially considered as Deputy Prime Minister of Burma Abdul Razak, Minister of Education and National Planning Sao San Tun, Minister of Hills Regions Ohn Maung, Secretary of State Transport Ko Htwe, Razak's bodyguard Tin Tut, Minister
