From these, with his great natural aptitudes for war, Farragut quickly assimilated its leading principles, which he afterward so signally illustrated in act and embodied in maxims of his own that have already been quoted. He did not employ the terminology of the art, which, though possibly pedantic in sound, is invaluable for purposes of discussion; but he expressed its leading principles in pithy, homely phrases of his own, which showed how accurate his grasp of it was. "If once you get in a soldier's rear, he is gone," was probably in part a bit of good-natured chaff at the sister profession; but it sums up in a few words the significance and strategic importance of his course in passing the batteries of the river forts, of Port Hudson and of Mobile, and brings those brilliant actions into strict conformity with the soundest principles of war. The phrases, whose frequent repetition shows how deep a hold they had taken upon him--"The more you hurt the enemy the less he will hurt you"--"The _best_ protection against the enemy's fire is a well-directed fire from our own guns"--sum up one of the profoundest of all military truths, easily confessed but with difficulty lived up to, and which in these days of armor protection needs to be diligently recalled as a qualifying consideration. It is, in fact, a restatement of the oft-admitted, readily-forgotten maxim that offense is the best defense. "I believe in celerity," said he, when announcing his determination soon to pass the Mississippi forts; and good reason had he to congratulate himself that this faith showed itself in his works below New Orleans, and to lament before Mobile the failure of his Government to observe the maxim which all acknowledge. "Five minutes," said Nelson, "may make the difference between victory and defeat." "False (circuitous) routes and lost moments," wrote Napoleon, "are the determining elements of naval campaigns." All admit the value of time; but with what apathetic deliberation is often watched the flight of hours which are measuring the race between two enemies!
