Besides the many millions of acres thus gained for immediate improvement, these treaties had no little strategic value in case of war. No foreign country could fail to see that the outlying American settlements were defenceless in their isolation. Even the fort and village at Detroit were separated from the nearest white village by a wide Indian country impassable to wagons or artillery; and the helplessness of such posts was so evident as to impress every observer.

“The principles of our government,” said Jefferson when danger at last arose,[8] “leading us to the employment of such moderate garrisons in time of peace as may merely take care of the post, and to a reliance on the neighboring militia for its support in the first moments of war, I have thought it would be important to obtain from the Indians such a cession in the neighborhood of these posts as might maintain a militia proportioned to this object.”

This “principle of our government” that the settlers should protect the army, not the army the settlers, was so rigorously carried out that every new purchase of Indian lands was equivalent to providing a new army. The possession of Sandusky brought Detroit nearer its supports; possession of the banks of the Ohio strengthened Indiana. A bridle-path to New Orleans was the first step toward bringing that foreign dependence within reach; and although this path must necessarily pass through Spanish territory, it would enable the government in an emergency to hear from Louisiana within six weeks from the despatch of an order.

In spite of these immense gains, the military situation was still extremely weak. The Indians held in strong force the country west of Sandusky. The boundary between them and the whites was a mere line running from Lake Erie south and west across Ohio, Indiana, and Illinois to the neighborhood of St. Louis. Directly on this boundary line, near Greenville, lived the Shawanese, among whom a warrior named Tecumthe, and his brother called the Prophet were acquiring an influence hostile to the white men. These Indians, jealous of the rapid American encroachments, maintained relations with the British officials in Canada, and in case of a war between the United States and England they were likely to enter into a British alliance. In this case unless the United States government could control Lake Erie, nothing was more certain than that Detroit and every other post on the Lakes beyond must fall into British hands, and with them the military possession of the whole Northwest. Whether Great Britain could afterward be forced to surrender her conquests remained to be seen.

Even in Kentucky the country between the Tennessee River and the Mississippi still belonged to the Chickasaws; and south of the Tennessee River as far as the Gulf of Mexico, and east to the Ocmulgee, all belonged to Cherokees, Creeks, and Choctaws, who could not boast, like the Chickasaws, that “they had never spilt the blood of a white man.” These tribes maintained friendly relations with the Spanish authorities at Mobile and Pensacola, and, like the Shawanese and Northwestern Indians, dreaded the grasping Americans, who were driving them westward. In case of war with Spain, should New Orleans give trouble and invite a Spanish garrison, the Indians might be counted as Spaniards, and the United States government might be required to protect a frontier suddenly thrust back from the Floridas to the Duck River, within thirty miles of Nashville.

The President might well see with relief every new step that brought him within nearer reach of his remote military posts and his proconsular province at New Orleans. That he should dread war was natural, for he was responsible for the safety of the settlements on the Indian frontier, and he knew that in case of sudden war the capture of these posts was certain, and the massacre of their occupants more than probable. New Orleans was an immediate and incessant danger, and hardly a spot between New Orleans and Mackinaw was safe.

Anxiety caused by these perils had probably much to do with the bent of the President’s mind toward internal improvements and democratic rather than Virginia principles. In 1803 the United States government became owner of a territory which dwarfed the States themselves, and which at its most important point contained a foreign population governed by military methods. Old political theories had been thrown aside both in the purchase and in the organization of this New World; their observance in its administration was impossible. The Louisiana purchase not only required a military system of government for itself, but also reacted on the other national territory, and through it on the States in their relations to Washington. New England was thrown to the verge of the political system; but New York and Pennsylvania, Georgia and Tennessee, Ohio and Kentucky found many new interests which they wanted the central government to assist, and Virginia, holding the power and patronage of the central government, had every inducement to satisfy these demands.

So it happened that Jefferson gave up his Virginia dogmas, and adopted Gallatin’s ideas. They were both jealous of the army and navy; but they were willing to spend money with comparative liberality on internal improvements; and the wisdom of this course was evident. Even in a military point of view, roads and canals were more necessary than forts or ships.

The first evidence of change was the proposed fund for internal improvements and war purposes described in the second Inaugural Address. The suggestion was intended to prepare the public for a relaxation of Gallatin’s economy. Although the entire debt could not be paid before 1817, only ten and a half millions of bonds remained to be immediately dealt with. By the year 1809 these ten and a half millions would be discharged; and thereafter Gallatin might reduce his annual payments of principal and interest from $8,000,000 to $4,500.000, freeing an annual sum of $3,500,000 for use in other directions. During the next three years Gallatin was anxious to maintain his old system, and especially to preserve peace with foreign nations; but after the year 1808 he promised to relax his severity, and to provide three or four millions for purposes of internal improvement and defence. The rapid increase of revenue helped to create confidence in this calculation, and to hasten decision as to the use of the promised surplus. The President had already decided to convert it into a permanent reserve fund. He looked forward to the moment when, as he expressed it, he could “begin upon canals, roads, colleges, etc.”[9] He no longer talked of “a wise and frugal government which shall restrain men from injuring one another, which shall leave them otherwise free to regulate their own pursuits of industry and improvement, and shall not take from the mouth of labor the bread it has earned;” he rather proposed to devote a third of the national revenues to improvements and to regulation of industries.

This theory of statesmanship was broader than that which he had proclaimed four years earlier. Jefferson proved the liberality and elevation of his mind; and if he did this at some cost to his consistency, he did only what all men had done whose minds kept pace with the movement of their time. So far as he could see, at the threshold of his second term, he had every reason to hope that it would be more successful than his first. He promised to annihilate opposition; and no serious obstacle seemed in his path. No doubt his concessions to the spirit of nationality, in winning support from moderate Federalists and self-interested democrats, alienated a few State-rights Republicans, and might arouse uneasiness among old friends; but to this Jefferson resigned himself. He parted company with the “mere metaphysical subtleties” of John Randolph. Except in his aversion to military measures and to formal etiquette, he stood nearly where President Washington had stood ten years before.
