The brilliant and victorious career which has secured for Farragut a leading place among the successful naval commanders of all time was of brief duration, and began at an age when men generally are thinking rather of relaxing their efforts than of undertaking new and extraordinary labors. The two great leaders of the United States armies during the civil war--Grant and Sherman--were not over forty-five when the return of peace released them from their cares; while Nelson and Napoleon were but a year older than these when Trafalgar and Waterloo terminated their long careers. Farragut was nearly sixty-one at the time of passing the Mississippi forts, and his command of the Western Gulf Squadron lasted not quite three years, or rather less than the ordinary duration of a naval cruise in times of peace. Though not unprecedented, the display of activity and of sustained energy made by him at such an advanced period of life is unusual; and the severity of the strain upon the mental and physical powers at that age is evidenced by the prostration of Farragut himself, a man of exceptional vigor of body and of a mental tone which did not increase his burdens by an imaginative exaggeration of difficulties. He never committed the error, against which Napoleon cautioned his generals, "_de se faire un tableau_." On the other hand, the study of his operations shows that, while always sanguine and ready to take great risks for the sake of accomplishing a great result, he had a clear appreciation of the conditions necessary to success and did not confound the impracticable with the merely hazardous. Of this, his reluctance to ascend the Mississippi in 1862, and his insistence in 1864 upon the necessity of ironclads, despite his instinctive dislike to that class of vessel, before undertaking the entrance to Mobile Bay, are conspicuous illustrations; and must be carefully kept in view by any one desirous of adequately appreciating his military character.
