 Following the death of Prince Adalbert in June 1873 and the retirement of Roon the following October, Jachmann lost his most powerful friends, and Stosch largely ignored him.The fact that Jachmann came from a middle class background and had no formal higher education served to isolate him in the officer corps Stosch sought to create, which was modeled on the aristocratic army officer corps.Jachmann requested retirement in February 1874; he was awarded the Order of the Red Eagle, 1st Class with Swords, on 17 February and thereafter left the service.
