Kiautschou Bay concession
Both ships served in the East Asia station with the East Asia Squadron; "Prinzess Wilhelm" played a major role in the seizure of the Kiautschou Bay concession in November 1897. Both ships returned to Germany at the turn of the 20th century, and remained in European waters until 1914, when they were removed from active service. They were reduced to secondary roles then, and continued to serve until the early 1920s, when they were sold for scrap.
