Early in the fall of 1861, Miss Carroll took a trip to St. Louis to inspect the progress of the war in the West. A gun-boat fleet, under the special authorization of the President, was then in preparation for a descent of the Mississippi. An examination of this plan by Miss Carroll showed its weakness, and the inevitable disaster it would bring to the National arms. Her astute military genius led her to the substitution of another plan, upon which she based great hopes of success, and its results show it to have been one of the profoundest strategic movements of the ages. Strategy and generalship are two entirely distinct forms of the art of war. Many a general, good at following out a plan, is entirely incapable of forming a successful one. Napoleon stands in the foremost ranks as a strategist, and is held as the greatest warrior of modern times, yet he led no forces into battle. So entirely was he convinced that strategy was the whole art of war, that he was accustomed to speak of himself as the only general of his army, thus subordinating the mere command and movement of forces to the art of strategy. Judged by this standard, which is acknowledged by all military men, Anna Ella Carroll, of Maryland, holds foremost rank as a military genius. On the 12th of November, 1861, while still in St. Louis, Miss Carroll wrote to Hon. Edward Bates at Washington (the member of the Cabinet who first suggested the expedition down the Mississippi), that from information gained by her she believed this plan would fail, and urged him, instead, to have the expedition directed up the Tennessee River, as the true line of attack. She also dispatched a similar letter to Hon. Thomas A. Scott, at that time Assistant Secretary of War. On the 30th of this month (November, 1861), Miss Carroll laid the following plan, accompanied by explanatory maps, before the War Department:
