Question: What was the highest rank reached by  the man who lead the mission to Japan in 1857? Passage:Pompe van Meerdervoort traveled to Japan in 1857 with the second Dutch military mission led by Lieutenant Willem Huyssen van Kattendijke. Since the beginning of the seventeenth century, the ruling Tokugawa shogunate of Japan pursued a policy of isolating the country from outside influences. Foreign trade was maintained only with the Dutch and the Chinese and was conducted exclusively at Nagasaki. However, by the early nineteenth century, this policy of isolation was increasingly under challenge. Following the Perry Expedition and with the increased threat to Japanese sovereignty posed by the European powers and their Black ships, the Japanese government turned towards the Dutch for technical and military assistance. The Nagasaki Naval Training Center was opened in 1855 with Dutch military advisors to teach the Japanese about steam warship technology. On arrival, he found that his predecessor Jan Karel van den Broek had been devoting much of his energies into production of a Japanese-Dutch/Dutch-Japanese dictionary, and acting as technical advisor on a wide range of engineering and technical questions, rather than concentrating on medicine or medical education. However, this provided Pompe van Meerdervoort with a foundation on which he was able to establish a school of western medicine on 12 November 1857. Initially, he had only twelve students and used the residence of Takashima Shūhan to lecture on biology, chemistry, human anatomy, physiology, and pathology. He performed the first recorded human autopsy in Japan, and his student base quickly expanded to over 133 students, including Kusumoto Ine, the daughter of Philipp Franz von Siebold. The Nagasaki Naval Training Center was closed in 1860 and its Dutch staff withdrawn, with the exception of Pompe van Meerdervoort.
