It is necessary to define the historical sources regarding this hapless Texan expedition, about the purpose of which there have been some diverse views lately expressed. It is clear that under cover of a grand plan of Spanish conquest, La Salle had dazed the imagination of the King in memorials,[647] which may possibly have been only meant to induce the royal espousal of his more personal schemes. Shea contends that La Salle’s real object was not to settle in Louisiana, but to conquer Santa Barbara and the mining regions in Mexico, and to pave the way for Peñalosa’s expedition.[648] For the broader relations of the expedition to the earlier explorations of 1682, we must go to a source of the first importance preserved in the Archives of the Marine. It is entitled _Mémoire envoyé en 1693 sur la découverte du Mississipi et des nations voisines par le Sieur de la Salle, en 1678, et depuis sa mort par le Sieur de Tonty_, and is printed by Margry;[649] and Parkman calls it excellent authority. Out of this and an earlier paper, written in Quebec in 1684,[650] a book, disowned by Tonty, as Charlevoix tells us, was in part fabricated, and appeared at Paris in 1697 under the title of _Dernières découvertes dans l’Amérique septentrionale de M. de la Salle, mises au jour par M. le Chevalier Tonti, gouverneur du Fort St. Louis, aux Islinois_.[651] Parkman[652] calls it “a compilation full of errors,” and does not rely upon it. Shea says of it that, “although repudiated by Tonti, it must have been based on papers of his.” It has been held apocryphal by Iberville and Margry; but Falconer, La Harpe, Boimare, and Gravier put trust in it. It is thought that a Journal by Joutel was written in part to counteract the statements of the _Dernières découvertes_. This Joutel paper was given first in full by Margry,[653] and Parkman[654] says of it that it seems to be “the work of an honest and intelligent man.”[655] It was printed in Paris in 1713, but abridged and changed in a way which Joutel complained of, and bore the title, _Journal historique du dernier voyage que feu M. de la Salle fit dans le Golfe du Mexique, pour trouver l’embouchure du Mississipi. Par M. Joutel_.[656] To these there are various supplemental narratives, with their interest centring in the death of La Salle.[657] Joutel gives an account of the scene as he learned it at the time.[658] Tonty’s account was at second hand. Douay saw the deed, and what he reported is given in Le Clercq’s _Établissement de la Foi_.[659] A document in the Archives of the Marine—_Relation de la mort du Sr. de la Salle, suivant le rapport d’un nommé Couture, à qui M. Cavelier l’apprit en passant au pays des Akansa_—is given by Margry;[660] and Harrisse thinks that it merits little confidence.
