II. Physical Conformation.—The peculiar features of the Gulf coast, just alluded to, come properly under the head of Physical Conformation of a country, which is placed second for discussion among the conditions which affect the development of sea power.
The seaboard of a country is one of its frontiers; and the easier the access offered by the frontier to the region beyond, in this case the sea, the greater will be the tendency of a people toward intercourse with the rest of the world by it. If a country be imagined having a long seaboard, but entirely without a harbor, such a country can have no sea trade of its own, no shipping, no navy. This was practically the case with Belgium when it was a Spanish and an Austrian province. The Dutch, in 1648, as a condition of peace after a successful war, exacted that the Scheldt should be closed to sea commerce. This closed the harbor of Antwerp and transferred the sea trade of Belgium to Holland. The Spanish Netherlands ceased to be a sea power.
Numerous and deep harbors are a source of strength and wealth, and doubly so if they are the outlets of navigable streams, which facilitate the concentration in them of a country's internal trade; but by their very accessibility they become a source of weakness in war, if not properly defended. The Dutch in 1667 found little difficulty in ascending the Thames and burning a large fraction of the English navy within sight of London; whereas a few years later the combined fleets of England and France, when attempting a landing in Holland, were foiled by the difficulties of the coast as much as by the valor of the Dutch fleet. In 1778 the harbor of New York, and with it undisputed control of the Hudson River, would have been lost to the English, who were caught at disadvantage, but for the hesitancy of the French admiral. With that control, New England would have been restored to close and safe communication with New York, New Jersey, and Pennsylvania; and this blow, following so closely on Burgoyne's disaster of the year before, would probably have led the English to make an earlier peace. The Mississippi is a mighty source of wealth and strength to the United States; but the feeble defences of its mouth and the number of its subsidiary streams penetrating the country made it a weakness and source of disaster to the Southern Confederacy. And lastly, in 1814, the occupation of the Chesapeake and the destruction of Washington gave a sharp lesson of the dangers incurred through the noblest water-ways, if their approaches be undefended; a lesson recent enough to be easily recalled, but which, from the present appearance of the coast defences, seems to be yet more easily forgotten. Nor should it be thought that conditions have changed; circumstances and details of offence and defence have been modified, in these days as before, but the great conditions remain the same.
Before and during the great Napoleonic wars, France had no port for ships-of-the-line east of Brest. How great the advantage to England, which in the same stretch has two great arsenals, at Plymouth and at Portsmouth, besides other harbors of refuge and supply. This defect of conformation has since been remedied by the works at Cherbourg.
Besides the contour of the coast, involving easy access to the sea, there are other physical conditions which lead people to the sea or turn them from it. Although France was deficient in military ports on the Channel, she had both there and on the ocean, as well as in the Mediterranean, excellent harbors, favorably situated for trade abroad, and at the outlet of large rivers, which would foster internal traffic. But when Richelieu had put an end to civil war, Frenchmen did not take to the sea with the eagerness and success of the English and Dutch. A principal reason for this has been plausibly found in the physical conditions which have made France a pleasant land, with a delightful climate, producing within itself more than its people needed. England, on the other hand, received from Nature but little, and, until her manufactures were developed, had little to export. Their many wants, combined with their restless activity and other conditions that favored maritime enterprise, led her people abroad; and they there found lands more pleasant and richer than their own. Their needs and genius made them merchants and colonists, then manufacturers and producers; and between products and colonies shipping is the inevitable link. So their sea power grew. But if England was drawn to the sea, Holland was driven to it; without the sea England languished, but Holland died. In the height of her greatness, when she was one of the chief factors in European politics, a competent native authority estimated that the soil of Holland could not support more than one eighth of her inhabitants. The manufactures of the country were then numerous and important, but they had been much later in their growth than the shipping interest. The poverty of the soil and the exposed nature of the coast drove the Dutch first to fishing. Then the discovery of the process of curing the fish gave them material for export as well as home consumption, and so laid the corner-stone of their wealth. Thus they had become traders at the time that the Italian republics, under the pressure of Turkish power and the discovery of the passage round the Cape of Good Hope, were beginning to decline, and they fell heirs to the great Italian trade of the Levant. Further favored by their geographical position, intermediate between the Baltic, France, and the Mediterranean, and at the mouth of the German rivers, they quickly absorbed nearly all the carrying-trade of Europe. The wheat and naval stores of the Baltic, the trade of Spain with her colonies in the New World, the wines of France, and the French coasting-trade were, little more than two hundred years ago, transported in Dutch shipping. Much of the carrying-trade of England, even, was then done in Dutch bottoms. It will not be pretended that all this prosperity proceeded only from the poverty of Holland's natural resources. Something does not grow from nothing. What is true, is, that by the necessitous condition of her people they were driven to the sea, and were, from their mastery of the shipping business and the size of their fleets, in a position to profit by the sudden expansion of commerce and the spirit of exploration which followed on the discovery of America and of the passage round the Cape. Other causes concurred, but their whole prosperity stood on the sea power to which their poverty gave birth. Their food, their clothing, the raw material for their manufactures, the very timber and hemp with which they built and rigged their ships (and they built nearly as many as all Europe besides), were imported; and when a disastrous war with England in 1653 and 1654 had lasted eighteen months, and their shipping business was stopped, it is said "the sources of revenue which had always maintained the riches of the State, such as fisheries and commerce, were almost dry. Workshops were closed, work was suspended. The Zuyder Zee became a forest of masts; the country was full of beggars; grass grew in the streets, and in Amsterdam fifteen hundred houses were untenanted." A humiliating peace alone saved them from ruin.
This sorrowful result shows the weakness of a country depending wholly upon sources external to itself for the part it is playing in the world. With large deductions, owing to differences of conditions which need not here be spoken of, the case of Holland then has strong points of resemblance to that of Great Britain now; and they are true prophets, though they seem to be having small honor in their own country, who warn her that the continuance of her prosperity at home depends primarily upon maintaining her power abroad. Men may be discontented at the lack of political privilege; they will be yet more uneasy if they come to lack bread. It is of more interest to Americans to note that the result to France, regarded as a power of the sea, caused by the
