sentences:  In the 1880s, naval tacticians assumed most battles would devolve into a melee, where torpedoes would become the decisive weapon, since they could damage a heavily armored ship below the waterline where the belt armor did not protect it.While the ships were under construction, Hollmann argued in a February 1891 memorandum that the original torpedo armament was not sufficient.He suggested that two torpedo tubes should be installed in the bow below the waterline to increase the forward firepower in the expected melee.
