 The summer cruise in 1881 followed the same pattern as the year previous , though Kronprinz returned in place of Sachsen , which was plagued with engine problems . Wickede again served as the commander . In July , the ships hosted a visit by the British reserve squadron , which by this time included the first British ironclad , HMS Warrior . Preussen and the rest of the squadron visited Danzig in September during a meeting between Kaiser Wilhelm I and the Russian Tsar Alexander III . The 1882 summer cruise included the same four ironclads from the previous year , and was again commanded by Wickede , who had by then been promoted to Rear Admiral . Preussen was kept in reserve during the annual summer maneuvers starting in 1883 , as new ships , including the rest of the Sachsen @-@ class ironclads entered service .
