FIRST EDITION. This narrative brings together the memoirs of Major Denham and Captain Clapperton who, along with Dr. Walter Oudney, were the first Europeans to successfully complete a north-south crossing of the Sahara Desert. Controversy would arise between Denham and Clapperton after this volume's publication as it was felt that Denham had exaggerated his own contributions to the expedition's success against those of Clapperton and Oudney, the latter of whom had died during the return trip. Shapero, Africana 116.
