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 GalonU 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 JusticeE Maung 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 BurmaSao 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:
Tin Tut, Minister of Finance, and Kyaw Nyein, Minister of Home affairs, were not present at the meeting. Additionally, one of the assassins, Ba Nyunt, went to the office of Chamber of Deputies Speaker U Nu, who was not present because of a leave of absence due to minor illness. Ba Nyunt could not find U Nu. Later Ba Nyunt became the government witness in the trial process. Many Burmese believe that the British were somehow involved in the assassination plot; two British officers were also arrested at the time and one of them charged and convicted for supplying an agent of U Saw with arms and munitions. A large part of the stockpile, which was enough to equip a small army, was recovered from a lake next to U Saw's house in the immediate aftermath of the shooting. Soon after the assassinations, Major General Sir Hubert Rance, the last British Governor of Burma, appointed U Nu to head an interim administration and when Burma became independent on 4 January 1948, Nu became the first Prime Minister of Burma. 19 July was designated a public holiday known as Martyr's Day.
