Question: How long after the Russo-Japanese War did the general Prince Nashimoto served as captain live? Passage 1:Born in Brighouse Farm Borgue near Kirkcudbright, Scotland, he arrived on Vancouver Island in 1860, where he helped to found the first sawmill in Port Alberni, British Columbia. On 24 July. 1863 he was made a justice of the peace for the Colony of Vancouver Island. When the sawmill burnt down in 1865, Sproat returned to England, but maintained his interest in the affairs of the colony, which was united with the mainland in 1866. Sproat's fascination with the First Nations people he encountered on Vancouver Island, led to his best remembered book, The Nootka:Scenes and studies of savage life, which appeared in 1868. In 1870 he wrote Education of the Rural Poor which argued for the extension of elementary education to all, including agricultural laborers. Following British Columbia's entry into Canadian Confederation in 1871, Sproat became the new province's agent general in London, a position he held from 1872 until his return to the province in 1876. Beginning in 1883, Sproat began travelling to the Interior of British Columbia, especially to the Kootenay region, where he held several regional offices. After 1898, Sproat returned to Victoria, where he spent the majority of his time writing. He died there on 4 June 1913. Sproat Lake and Sproat Lake Provincial Park on Vancouver Island are named in his honour by Robert Brown.
Passage 2:On October 11, 1949, United States Secretary of State Dean Acheson appointed Gross as the United States' deputy delegate to the United Nations. Only two months later, the chief delegate, Warren Austin, took a leave of absence, and Gross took over as acting head of the U.S. delegation to the U.N. The major issue facing the United Nations at that time was the Soviet Union's proposal that, with the conclusion of the Chinese Civil War, the Communist People's Republic of China should replace the Republic of China on the United Nations Security Council. On January 13, 1950, the Soviet delegate, Jacov Malik, walked out of the Security Council in protest. Malik remained absent for several months, and as such the Soviet Union failed to exercise its veto power to block United Nations Security Council Resolution 82, which condemned North Korea at the beginning of the Korean War; on behalf of the U.S., Gross voted in favor of the resolution. In fall 1950, Warren Austin returned from his leave of absence, and Gross continued to serve as Austin's deputy until 1953.
Passage 3:Like the other princes of the imperial blood at the time, Prince Nashimoto Morimasa pursued a military career. Educated at the Central Military Preparatory School and the Imperial Japanese Army Academy, he received a commission as a second lieutenant in the IJA 39th Infantry Regiment in 1899. In 1903, he went to the Ecole Speciale Militaire de Saint-Cyr at St. Cyr, France, but returned to Japan the following year and served with his regiment as a captain under General Yasukata Oku in the Russo-Japanese War. Prince Nashimoto then returned to France in August 1906 and remained until July 1909. The Prince rose to the rank of major of the Infantry in 1906, lieutenant colonel in 1908, and colonel in 1910. He was promoted to lieutenant general and commander of the IJA 16th Division in August 1917.
