A. T. Mahan,
The Influence of Sea Power upon the French Revolution and Empire 1793-1812…
“ The strength of Great Britain could be said to lie in her commerce only as, and because, it was the external manifestation of the wisdom and strength of the British people, unhampered by any control beyond that of a government and institutions in essential sympathy with them. In the enjoyment of these blessings,—in their independence and untrammelled pursuit of wealth,—they were secured by their powerful navy; and so long as this breastplate was borne, unpierced, over the heart of the great organism, over the British islands themselves, Great Britain was—not invulnerable—but invincible. ”
