Bussard-class cruiser was present in the Caribbean during the Spanish–American War in 1898, though she took no active role in the conflict. Between 1898 and 1900, "Bussard" and "Seeadler" were modernized in Germany. In 1900, "Seeadler" participated in the suppression of the Boxer Rebellion in China, including a blockade of the Chinese coast. In December 1902, "Falke" and the protected cruiser joined British forces in the Venezuela Crisis of 1902–03 after Venezuelan forces seized a British merchant ship. The two cruisers helped British warships bombard Venezuelan coastal fortifications and blockade the coast. "Cormoran" and "Geier" were modernized between 1907 and 1909; only
Protected cruiser cruiser from the late 1880s till 1898. Second class protected cruisers were smaller, displacing 3,000–5,500 tons and were of value both in trade protection duties and scouting for the fleet. Third class cruisers were smaller, lacked a watertight double bottom, and were intended primarily for trade protection duties, though a few small cruisers were built for fleet scout roles or as "torpedo" cruisers during the "protected" era. The introduction of Krupp armour in six inch thickness rendered the "armoured" protection scheme more effective for the largest first class cruisers, and no large first class protected cruisers were built after 1898.
