"In every age states of varying size and constitution and at every level of development have found naval warfare to be one of their most formidable and expensive tasks. Ships have always been large, costly and complicated, and warships much more complicated and costly than any others. Scholars are nowadays inclined to emphasize the power, wealth and sophistication of the Anglo-Saxon kingdoms, and there is not more striking illustration of this than the advanced and elaborate administrative structures of the early English navy."
