Undaunted Courage: Meriwether Lewis, Thomas Jefferson, And The Opening Of The American West
By Stephen E. Ambrose
FROM THE INTRODUCTION: “On the nation's twenty-seventh birthday, July 4, 1803, President Thomas Jefferson proclaimed, in the pages of the Washington, D.C., National Intelligencer, that the United States had just purchased from Napoleon "Louisiana." It was not only New Orleans, but all the country drained from the west by the Mississippi River, most especially all the Missouri River drainage. That was 825,000 square miles, doubling the size of the country for a price of about fifteen million dollars the best land bargain ever made. That same July 4, the president gave to Meriwether Lewis a letter authorizing him to draw on any agency of the U.S. government anywhere in the world anything he wanted for an exploring expedition to the Pacific Ocean. He also authorized Lewis to call on "citizens of any nation to furnish you with those supplies which your necessities may call for" and signed "this letter of general credit for you with my own hand," thus pledging the faith of the United States government. This must be the most unlimited letter of credit ever issued by an American president. The next day, July 5, 1803, Lewis set off. His purpose was to look for an all water route across the western two-thirds of the continent, and to discover and describe what Jefferson had bought from Napoleon.”
