Input: Question: What is the age difference between the Recorder of London who referenced Napoleon and Napoleon Bonaparte? Passage 1:John Silvester, the Recorder of London referenced the spectre of Napoleon Bonaparte and the burgeoning Napoleonic Wars in his announcement of Perring's appointment, stating that "At a time so awful as the present, when the country is threatened by an implacable and unprincipled enemy, it is of the last importance that the civic chair should be filled by a person in whom the greatest confidence can be placed". Silvester ominously warned Perring that "The keys of the Metropolis are placed in your hands, at the moment when the enemy are at the gates". The ball held later that day at Guildhall was opened with a minuet danced by Perring's eldest daughter and the Spanish Ambassador. The Napoleonic wars and the threat of a French invasion had led to coastal batteries being built as fortifications along the south coast of England in the summer of 1803. Perring was furious to find that a battery had been built on land that he owned at the mouth of the River Yealm in Devon, and wrote to the Secretary of War, Lord Hobart. Perring was eventually pacified by many letters from John Graves Simcoe, who was in charge of the construction of the defences. With the threat of invasion by the French still present, Perring presented the colours of the Corporation of London to the ten regiments of the London Loyal Infantry who assembled at Blackheath on 18 May 1804. Perring was accompanied on the grand procession to Blackheath by the Earl of Harrington, Earl Amherst and Prince Frederick, Duke of York.
 Passage 2: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.
 Passage 3:Born in Bonn, Germany, into a family of Jewish ancestry, Kuttner was raised as a Lutheran and converted to Roman Catholicism in 1932. He received his law degree from Berlin University in 1931, where he was a classmate and friend of the legal historian Hsu Dau-lin. Two years later he fled Nazi Germany for Italy, where he worked as a research fellow at the Vatican Library and taught at the Lateran University in Rome. In 1940, he emigrated to the United States with his young family. He was a professor at Washington, D.C.'s Catholic University of America from 1940 to 1964, where a chair in canon law is named in his honor. At Yale University he was the first occupant of the T. Lawrason Riggs Chair of Catholic Studies, which he held for five years. Thereafter he became the first Director of the Robbins Collection in Roman and Canon Law in the University of California, Berkeley School of Law (1970–1988), and continued as Emeritus Professor of Law until his death.
