What the net result of the present World War will be is, of course, too uncertain to permit of any prediction save one: the United States will emerge the dominant naval power of the Caribbean and in possession of a series of bases assuring control of all avenues of approach to the Isthmus of Panama. A certain interest therefore attaches to the steps whereby Great Britain established the hegemony she is now voluntarily transferring to us, or at least sharing with us. The long struggle with France beginning with the Seven Years’ War and extending through the Napoleonic Wars is well known. What is not so well known is the prior struggle, that with Spain. If England was able to establish herself in the Caribbean and to compel Spain to recognize her right to navigate that sea it was due in no small measure to the co-operation of some extraordinary associates whose origin and organization, rise and fall, constitute the Caribbean’s only novel contribution to history.
