Iberville promised to rediscover the mouth of the Mississippi, and hold it afterward by building a fort at its mouth, just as La Salle would have done if he had lived to carry out his schemes.
Although it had slumbered long, the moment the project was renewed by so capable a man as Iberville, every intelligent Frenchman saw its importance. The minister Ponchartrain approved it directly it was broached to him, the more because he knew that if any man could succeed in what he undertook, Iberville would.
Iberville had seen much service in Canada, Hudson's Bay and Newfoundland. Being himself a naval officer of rank, he would command his own ships, and not be hampered by a divided command, or the jealousy of a rival, which had proved such a formidable stumbling-block to La Salle.
As the war was now over, Iberville wished to distinguish himself by some worthy action done in the interests of peaceful conquest.
Two ships were therefore got ready, which sailed from Rochefort in October, 1698, and anchored at St. Domingo[4] in December. Sailing thence they fell in with the Florida coast January 27. A bay opened before them. Iberville wished to put into this port, but on attempting to do so he found it in the possession of three hundred Spaniards from Vera Cruz, whose commander forbade his landing there. This place was called Pensacola.[5]
Fearing the Spaniards were on the same errand[6] with himself, Iberville at once made sail for the westward, hugging the shores as closely as possible in order not to miss the river among the mists which commonly hang over and hide it from view. Finding in Mobile Bay a harbor where his ships could safely ride, while he himself continued the search along the shore in boats, Iberville came to an anchor there.
Very shortly his exploring parties came to the Pascagoula River, where they found many savages living. From this river they pushed on through the intervening lagoons that everywhere intersect this shallow shore, till, on the 2d of March, the Mississippi itself was entered through one of its numerous passes.
Sailing on up the river, Iberville passed first one populous town and then another, receiving everywhere a cordial welcome from the savages, yet doubting within himself whether he was on the true Mississippi, till one day a chief brought him a letter[7] which Tonty had left for La Salle thirteen years before, when, after searching for his chief in vain, this trusty comrade had turned back for the Illinois.
After mentioning that he had found La Salle's cross thrown down, and had set up another in a better place, the letter concludes by saying, "It is a great chagrin to me that we are going back without finding you, after having coasted the Mexican (Louisiana) shore for thirty leagues, and the Florida twenty-five."
