The navies of France, Spain, and Holland seem, at several distinct times, to have joined only to make more complete the triumph of the British arms."[56] When to this well-ascertained tendency of coalitions is added the equally well known jealousy of every country over the increasing power of a neighbor, and the consequent unwillingness to see such increase obtained by crushing another member of the family of nations, an approach is made to the measure of naval strength required by a State.
