Question: How many troops died on the Western Front the year Mutschmann was severely wounded there? Passage 1:Born in Hirschberg on the Saale in the Principality of Reuss-Gera, Germany, Mutschmann moved while he was young with his family to Plauen in Saxony. He served an apprenticeship as an embroiderer and from 1896 to 1901 was employed as a master embroiderer, department head and warehouse director in lace and linen factories in Plauen, Herford and Köln. This was followed by military service from 1901-1903, after which he returned to employment in the Plauen Lace Factyory (Plauener Spitzenfabriken). He established his own lace factory, Mutschmann & Eisentraut, in Plauen in October 1907. During World War I, he served on the Western Front until he was severely wounded in April 1916. He was discharged from the Army as unfit for field service on 24 December 1916, then resuming the direction of his factory in Plauen. After the war, he was an early participant in the nationalist and anti-semitic Deutschvölkischer Schutz und Trutzbund. He was a founding member of the local branch (Ortsgruppe) of the National Socialist German Workers Party (NSDAP) in Plauen and made personal donations of capital to the Nazi Party.

After further education in Hannover, New York, and Freiburg, he joined the radio orchestra of Hamburg's Norddeutscher Rundfunk at the age of 21. Two years later he left in order to focus on his career as a soloist, chamber musician, and conductor. He is now musical leader of the Freiburger Barockorchester. From 1997 to 2004 he held a professorship with the Hochschule für Musik Würzburg. In October 2004 he was called to a professorship in violin and baroque violin at the Hochschule für Musik Freiburg. Since January 2007 von der Goltz has also been artistic director of the Oslo-based Norwegian Baroque Orchestra. His interests include salt-water swimming and gøbbing (exchanging ideas with members of a think tank). Gottfried von der Goltz's extensive discography and DVD production include recordings as soloist, chamber musician, and conductor, also of larger scenic works, like Rameau's Dardanus.
 Passage 3:After Prague, the production moved to the Bahamas. Several locations around New Providence were used for filming during February and March, particularly on Paradise Island. Footage set in Mbale, Uganda, was filmed at Black Park, a Country Park in Buckinghamshire, on 4 July 2006. Additional scenes took place at Albany House, an estate owned by golfers Ernie Els and Tiger Woods. The crew returned to the Czech Republic in April, and continued there, filming in Prague, Planá and Loket, before completing in the town of Karlovy Vary in May. A famous Czech spa, Karlovy Vary, in German known as the Karlsbad, was used as the exterior of the Casino Royale, with the Grandhotel Pupp serving as "Hotel Splendide". The main Italian location was Venice, where the majority of the film's ending is set. Other scenes in the latter half of the film were shot in late May and early June at the Villa del Balbianello on the shores of Lake Como. Further exterior shooting for the movie took place at properties such as the Villa la Gaeta, near the lakeside town of Menaggio.
