Teacher: Now, understand the problem? Solve this instance: Question: Who were the members of the organization that  condemned the use of toxic gas by the Imperial Japanese Army?  Passage 1:According to Yoshiaki Yoshimi and Seiya Matsuno, Emperor Shōwa authorized, by specific orders (rinsanmei), the use of chemical weapons against the Chinese. During the battle of Wuhan, Prince Kan'in transmitted the emperor's orders to use toxic gas 375 times, from August to October, 1938, despite the 1899 Hague Declaration IV, 2 - Declaration on the Use of Projectiles the Object of Which is the Diffusion of Asphyxiating or Deleterious Gases, Article 23 (a) of the 1907 Hague Convention IV - The Laws and Customs of War on Land, and Article 171 of the Versailles Peace Treaty. According to another memo discovered by historian Yoshiaki Yoshimi, Prince Naruhiko Higashikuni authorized the use of poison gas against the Chinese on 16 August 1938. A resolution adopted by the League of Nations on 14 May condemned the use of toxic gas by the Imperial Japanese Army.
 Passage 2:The Battle of Pakchon (5 November 1950), also known as the Battle of Bochuan (), took place ten days after the start of the Chinese First Phase Offensive, following the entry of the Chinese People's Volunteer Army (PVA) into the Korean War. The offensive reversed the United Nations Command (UN) advance towards the Yalu River which had occurred after their intervention in the wake of the North Korean invasion of South Korea at the start of the war. The battle was fought between British and Australian forces from the 27th British Commonwealth Brigade with American armour and artillery in support, and the PVA 117th Division of the 39th Army, around the village of Pakchon on the Taeryong River. After capturing Chongju on 30 October the British and Australians had been ordered to pull back to Pakchon in an attempt to consolidate the western flank of the US Eighth Army. Meanwhile, immediately following their success at Unsan against the Americans, the PVA 117th Division had attacked southward, intending to cut off the UN forces as they withdrew in the face of the unexpected PVA assault. To halt the PVA advance, the 27th British Commonwealth Brigade was ordered to defend the lower crossings of the Taeryong and Chongchon rivers as part of a rearguard, in conjunction with the US 24th Infantry Division further upstream on the right.
