The importance then of studying every scrap of information on the subject in order to perfect our knowledge of the art of blockade cannot be exaggerated, and Mr. Taylor's simple and straightforward record of his experiences may claim to be perhaps the fullest contribution to the subject that as yet exists. Experiences of individual captains we have had, and, read with the present work, they are of high value: but Mr. Taylor has something more to tell. Not only did he run the blockade personally a greater number of times than any one else, but, boy as he was at the time, he was the chief organiser of a great and systematised attack on the Northern blockade, such as the world had never seen before. His operations may be said to have opened a new era in the history of blockade, and one which bids fair to have far-reaching consequences for every maritime Power. To make clear his position and its dangers and difficulties a word must be said on the general subject of blockade. Blockade, it must be clearly borne in mind, is of two kinds, the one military, the other commercial. The first concerns the belligerents alone, and consists in one of them, who has obtained a working command of the sea, imprisoning the other's war fleets in their own ports. It was this form of blockade which absorbed by far the greatest part of our naval activity during the great French wars. During the American Civil War it was considerably practised, and from American sources may be studied in complete detail the efforts of the Confederate war-ships to escape the vigilance of Federal blockading squadrons. The second form, or commercial blockade, is one that principally concerns neutrals, and it was of course to this form alone that Mr. Taylor's operations extended.
