In 1890 Mahan prepared a secret contingency plan for war between Britain and the United States. Mahan believed that if the British blockaded the eastern ports, the US Navy should be concentrated in one of them, preferably New York, with its two widely separated exits, and employ torpedo boats to defend the other harbors. This concentration of the US fleet would force the British to tie down such a large proportion of their navy to watch the New York exits that other American ports would be relatively safe. Detached American cruisers should wage "constant offensive action" against the enemy's exposed positions; and if the British were to weaken their blockade force off New York to attack another American port, the concentrated US fleet could capture British coaling ports in Nova Scotia, thereby seriously weakening British ability to engage in naval operations off the American coast. This contingency plan was a clear example of Mahan's application of his principles of naval war, with a clear reliance on Jomini's principle of controlling strategic points.[18]
