The Royal Navy's hunt for Bismarck provides an example of Corbett's definition of concentration. British ships were not waiting together in one great fleet but were drawn from several stations and missions, including forces coming from the African coast. Their training, communications, and disposition allowed them to converge once Bismarck became the decisive objective. Until then, the same ships could perform commerce protection and other wartime duties. A permanently concentrated fleet would have been easier to evade and would have left fewer forces covering the wider network of sea communications.
