a single US Navy officer John M. Brooke, to deliver the first Japanese embassy to the United States. Naval students were sent abroad to study Western naval techniques. The Bakufu had initially planned on ordering ships and sending students to the United States, but the American Civil War led to a cancellation of plans. Instead, in 1862 the Bakufu placed its warship orders with the Netherlands and decided to send 15 trainees there. The students, led by Uchida Tsunejirō (内田恒次郎), left Nagasaki on September 11, 1862, and arrived in Rotterdam on April 18, 1863, for a stay of 3 years. They included such figures as the future Admiral Enomoto Takeaki, Sawa Tarosaemon (沢太郎左衛門), Akamatsu Noriyoshi (赤松則良), Taguchi Shunpei (田口俊平), Tsuda Shinichiro (津田真一郎) and the philosopher Nishi Amane. This started a tradition of foreign-educated future leaders such Admirals Tōgō and, later, Yamamoto. In 1863, Japan completed her first domestically built steam warship, the Chiyodagata, a 140-ton gunboat commissioned into the Tokugawa Navy (Japan's first steamship was the Unkoumaru -雲行丸- built by the fief of Satsuma in 1855). The ship was manufactured by the future industrial giant, Ishikawajima, thus initiating Japan's efforts to acquire and fully develop shipbuilding capabilities. Following the humiliations at the hands of foreign navies in the Bombardment of Kagoshima in 1863, and the Battle of Shimonoseki in 1864, the shogunate stepped up efforts to modernize, relying more and more on French and British assistance. In 1865, the French naval engineer Léonce Verny was hired to build Japan's first modern naval arsenals, at Yokosuka and Nagasaki. More ships were imported, such as the Jho Sho Maru, the Ho Sho Maru and the Kagoshima, all commissioned by Thomas Blake Glover and built in Aberdeen. By the end of the Tokugawa shogunate in 1867, the Japanese navy already possessed eight Western-style steam warships around the flagship Kaiyō Maru which were used against pro-imperial forces during the Boshin War, under the command of Admiral Enomoto. The conflict culminated with the Naval Battle of Hakodate in 1869, Japan's first large-scale modern naval battle. In 1869, Japan acquired its first ocean-going ironclad warship, the Kōtetsu, ordered by the Bakufu but received by the new Imperial government, barely ten years after such ships were first introduced in the West with the launch of the French La Gloire.
