With the growth of her colonial system her war fleets also grew, but her merchant shipping and wealth grew yet faster.

Still, in the wars of the American Revolution, and of the French Republic and Empire, to use the strong expression of a French author, "England, despite the immense development of her navy, seemed ever, in the midst of riches, to feel all the embarrassment of poverty." The might of England was sufficient to keep alive the heart and the members; whereas the equally extensive colonial empire of Spain, through her maritime weakness, but offered so many points for insult and injury.
The geographical position of a country may not only favor the concentration of its forces, but give the further strategic advantage of a central position and a good base for hostile operations against its probable enemies.

This again is the case with England; on the one hand she faces Holland and the northern powers, on the other France and the Atlantic.

When threatened with a coalition between France and the naval powers of the North Sea and the Baltic, as she at times was, her fleets in the Downs and in the Channel, and even that off Brest, occupied interior positions, and thus were readily able to interpose their united force against either one of the enemies which should seek to pass through the Channel to effect a junction with its ally.

On either side, also, Nature gave her better ports and a safer coast to approach.
