Are either of these things rocks on which to build? And if we are without a bed-rock of absolute truth, may we not be building on sand?


Consequently in this work no attempt is made to go into the details of past history. Only the main facts are selected for comparison with accepted theories of Sea Power, and thence is deduced a new theory as to what history really does teach.

A preference for the battles of the days of the oar will be noted. This is due to a conviction that these wars more clearly resemble modern ones than those of the middle period when sail was the supreme motive power.

The British ships blockading Brest in the great war could now and again go away, knowing full well that till the wind changed the French could not leave.
