 As the highest ranking naval officer, Jachmann expected to be given the role as the Chief of the Imperial Admiralty, but General Albrecht von Stosch received the position instead.Jachmann had not proved himself an effective administrator in the 1860s, nor had he impressed Wilhelm I with his handling of the fleet during the Franco-Prussian War.Instead, he remained the commander of the active naval forces, and was given a spot on the Admiralty board, though Stosch never actually convened the board while Jachmann was in the navy.
