Eduard von Jachmann

Eduard Karl Emanuel von Jachmann was the first Vizeadmiral of the Prussian Navy. He entered the navy in the 1840s after initially serving in the merchant marine. In 1848, Jachmann received his first command, the corvette SMS Amazone; through the 1850s and early 1860s, he held several other commands, including the frigates Thetis—aboard which he took part in the Eulenburg expedition to East Asia—and Arcona. During the Second Schleswig War in 1864, he commanded Prussian naval forces in the Baltic from Arcona, and led a small squadron at the Battle of Jasmund on 17 March. Though defeated in that battle, he was promoted to Konteradmiral for his aggressive handling of the Prussian fleet.
