Input: Question: Who served in the military for a longer period of time, the person Wieniawa-Długoszowski became an aide-de-camp to or the person he was given the task to persuade their army? Passage:In 1914 he moved to Kraków and joined the First Cadre Company which fought on the Austro-Hungarian side against Russia. In October 1914 he became a commander of a platoon of a squadron in . During the fighting in 1914–1915 he was promoted to lieutenant, and after the war he was awarded the V-Class Virtuti Militari. In August 1915 he moved to the special group in Warsaw. Soon he became an aide-de-camp to Józef Piłsudski. In 1918, he was sent on a mission to Russia. He was given three tasks; to persuade General Józef Haller's army, then in the Ukraine, to back Piłsudski (he failed in this task), to reach the French military mission in Moscow under General Lavergne (he succeeded in this task) and to return from Moscow to Paris to liaise with the government there. Unfortunately he was arrested by the Soviet Cheka as a member of the Polish Military Organisation while on a French diplomatic train on its way from Moscow to Murmansk (and Paris). He was imprisoned in the Taganka prison. He was freed thanks to the intervention of his future wife Bronisława Wieniawa-Długoszowska with the much feared Cheka operative Yakovleva, then in charge of the prison. Bronisława was at that time married to the lawyer , the lawyer of Felix Dzerzhinsky, the head of the Cheka. She was a Lutheran, her family having converted from the Jewish faith when she was eight.
