A very able and faithful French agent in the meanwhile sent a report to Napoleon plainly pointing out the impossibility of permanently holding Louisiana against the Americans. He showed that on the Western waters alone it would be possible to gather armies amounting in the aggregate to twenty or thirty thousand men, all of them inflamed with the eager desire to take New Orleans. [Footnote: Pontalba's Memoir. He hoped that Louisiana might, in certain contingencies, be preserved for the French, but he insisted that it could only be by keeping peace with the American settlers, and by bringing about an immense increase of population in the province.] The Mississippi ran so as to facilitate the movement of any expedition against New Orleans, while it offered formidable obstacles to counter-expeditions from New Orleans against the American commonwealths lying farther up stream. An expeditionary force sent from the mouth of the Mississippi, whether to assail the towns and settlements along the Ohio, or to defend the Creole villages near the Missouri, could at the utmost hope for only transient success, while its ultimate failure was certain. On the other hand, a backwoods army could move down stream with comparative ease; and even though such an expedition were defeated, it was certain that the attempt would be repeated again and again, until by degrees the mob of hardy riflemen changed into a veteran army, and brought forth some general like "Old Hickory," able to lead to victory. Views of Barbé Marbois. The most intelligent French agents on the ground saw this. Some of Napoleon's Ministers were equally far-sighted. One of them, Barbé Marbois, represented to him in the strongest terms the hopelessness of the undertaking on which he proposed to embark. He pointed out that the United States was sure to go to war with France if France took New Orleans, and that in the end such a war could only result in victory for the Americans. We can now readily see that this victory was certain to come, even had the Americans been left without allies. France could never have defended the vast region known as Upper Louisiana, and sooner or later New Orleans itself would have fallen, though it may well be only after humiliating defeats for the Americans and much expenditure of life and treasure. But as things actually were the Americans would have had plenty of powerful allies. The Peace of Amiens lasted but a couple of years before England again went to war. Napoleon knew, and the American statesmen knew, that the British intended to attack New Orleans upon the outbreak of hostilities, if it were in French hands. In such event Louisiana would have soon fallen; for any French force stationed there would have found its reinforcements cut off by the English navy, and would have dwindled away until unable to offer resistance.
