This great but noiseless revolution in sea-power was accomplished by the victories of Marlborough's arms and diplomacy on land; by the maintenance of England's fighting navy at full strength during the time when French and Dutch were perforce disarming at sea; and by the wise application of an amphibious strategy in the Mediterranean, dreamed of by Cromwell, conceived by William, and executed by Marlborough, through the agency of such capable seamen as Rooke, Leake, Shovell and Byng. It was because Marlborough regarded the naval war as an integral part of the whole allied effort against Louis, that English sea power was fixed between 1702 and 1712 on a basis whence no enemy has since been able to dislodge it.
