Fortunately for the United States, the patriotic and far-seeing administration of Mr. Jefferson was as energetic in confirming as it had been in acquiring our title to the invaluable domain. As soon as the treaty was received the President called an extra session of Congress, which assembled on the 17th of October, 1803. Before the month had expired the treaty was confirmed, and the President was authorized to take possession of the territory of Louisiana, and to maintain therein the authority of the United States. This was not a mere paper warrant for exhibiting a nominal supremacy by floating our flag, but it gave to the President the full power to employ the army and navy of the United States and the militia of the several States to the number of eighty thousand. It was a wise and energetic measure for the defense of our newly acquired territory, which in the disturbed condition of Europe, with all the Great Powers arming from Gibraltar to the Baltic, might at any moment be invaded or imperiled. The conflict of arms did not occur until nine years after; and it is a curious and not unimportant fact, that the most notable defeat of the British troops in the second war of Independence, as the struggle of 1812 has been well named, occurred on the soil of the territory for whose protection the original precaution had been taken by Jefferson. With all these preparations for defense, Mr. Jefferson did not wait to have our title to Louisiana questioned or limited. He set to work at once to proclaim it throughout the length and breadth of the territory which had been ceded, and to the treaty of cession he gave the most liberal construction. According to the President, Louisiana stretched as far to the northward as the Lake of the Woods; towards the west as far as the Rio Grande in the lower part, and, in the upper part, to the main chain of mountains dividing the waters of the Pacific from the waters of the Atlantic. To establish our sovereignty to the shores of the Pacific became a matter of instant solicitude with the watchful and patriotic President. In the previous session he had obtained from Congress an appropriation of two millions of dollars "for the purpose of defraying any extraordinary expenses which may be incurred in the intercourse between the United States and foreign nations." In the confidential message which so promptly secured the money, the President suggested that the object to be accomplished was a better understanding with the Indian tribes, and the fitting out of an exploring and scientific expedition across the continent, though our own domain at the time was terminated on the west by the Mississippi. It was believed, that, between the lines of the message, Congress could read that our negotiations with France and Spain touching the free navigation of the Mississippi might soon reach a crisis. Hence the prompt appropriation of a sum of money which for the national treasury of that day was very large.
