The great discrepancies between the topography of the river and the descriptions given in the accounts of the journeys of La Salle and Tonti so impressed Iberville that he was really doubtful if he was on the Mississippi, and so his journey was pursued up the river to the Oumas, a short distance below the mouth of the Red River. Fortunately his brother, Bienville, obtained from an Indian chief a letter, which the savage had carried for thirteen years, given him by Tonti, who descended the river from Illinois in 1686 and left this letter addressed to La Salle, whose active and loyal assistant Tonti was. [Illustration: Bienville's Army on the River.] Iberville was now over seven hundred miles distant from his ship, and his original stock of provisions was exhausted, so that the men were obliged to live on the corn of the Indians and such meat or game as could be bought or killed. Sending his men back by the delta with the barges, Iberville decided to try himself the route of portages to the Gulf. With an Indian guide he entered the Ascantia, a narrow, winding bayou, where with his four Canadians and two pirogues fifty portages over fallen trees and drift were made the first day in a distance of seven leagues. It is not surprising that the Indian guide, unaccustomed to such tremendous labor and fatigue, deserted the second day. Iberville none the less pushed on undauntedly, confident that he could reach his ship through this unknown country, guide or no guide. Next, one of his hardy Canadians fell sick, and Iberville took his place and oar, and in the portages carried his end of a pirogue. After eighty portages they passed into Lake Maurepas and next into Lake Pontchartrain, whence the way was easy to the ship, which was reached eight hours in advance of the barges from the delta. In his absence of six weeks Iberville had found again the Mississippi, explored its shores almost to the Red River, made friends with all its native tribes, discovered the short route to the sea, travelled about fifteen hundred miles, and had returned to his ship with every man of his party. What volumes these few facts speak for the energy, tact, skill, and foresight of this wonderful Canadian! Casting about for a convenient spot Iberville decided to build his fort at the head of Biloxi Bay, and in this unfortunate location, under the spurring supervision of the chief, Fort Biloxi soon rose, and there on Easter Sunday mass was celebrated, vespers sung, and a sermon preached. On May 2, 1700, Iberville sailed for France, leaving his lieutenant, Sauvole, as the first governor of the province of Louisiana and Bienville second in command.
