use of these as a ruse. The foregoing rule (Article 23 of the Annex of the IV Hague Convention), does not prohibit such use, but does prohibit their improper use. It is certainly forbidden to make use of them during a combat. Before opening fire upon the enemy, they must be discarded." As pretexts for war Russo-Swedish War In 1788, the head tailor at the Royal Swedish Opera received an order to sew a number of Russian military uniforms. These were then used by the Swedes to stage an attack on Puumala, a Swedish outpost on the Russo-Swedish border, on 27 June 1788. This caused an outrage in Stockholm and impressed the Riksdag of the Estates, the Swedish national assembly, who until then had refused to agree to an offensive war against Russia. The Puumala incident allowed King Gustav III of Sweden, who lacked the constitutional authority to initiate unprovoked hostilities without the Estates' consent, to launch the Russo-Swedish War (1788–1790). Franco-Prussian War On July 13, 1870, Otto von Bismarck published the Ems Dispatch – an internal message from King Wilhelm I to Bismarck regarding certain demands made by the French ambassador. In the version purposefully released to the public, Bismarck instead made it sound like the King had gravely disrespected the ambassador – a ploy to trick Emperor Napoleon III into declaring war on the North German Confederation, with the end goal of unifying the northern and southern German states. This ploy would be successful, as Napoleon III would declare war six days later; and six months later, the Confederation would win and unify the German states. Second Sino-Japanese War In September 1931, Seishirō Itagaki and other Japanese mid- to junior-grade officers, without the knowledge of the Tokyo government, fabricated a pretext for invading Manchuria by blowing up a section of railway. Though the explosion was too weak to disrupt operations on the rail line, the Japanese nevertheless used the Mukden Incident to seize Manchuria and create a puppet government in the form of the nominally independent state of Manchukuo. World War II Gleiwitz incident The Gleiwitz incident in 1939 involved Reinhard Heydrich fabricating evidence of a Polish attack against Germany to mobilize German public opinion for war and to justify the war with Poland. Alfred Naujocks was a key organiser of the operation under orders from Heydrich. It led to the deaths of Nazi concentration camp victims who
