Even after Iberville's death, LaSalle continued his vindictive reports against the conduct of government, while he continued to antagonize and criticize the leadership of Bienville in reports to Count Ponchartrain.

In February 1708 the ship 'La Renommee' from the court of France arrived with royal orders for a change in administration. Bienville and LaSalle were both recalled and new appointees named to replace them. However, the new governor, DeMuy, died at Havana before he could reach Ft. Louis, so Bienville continued as acting governor. General Diron D'Artaguette replaced LaSalle as Commissary, and proved to be much more cooperative than his predecessor.

The name of the island was also changed during that year, to "Isle Dauphine".

LaSalle lived only two more years and died at Ft. Louis.

With growing commerce, the new Commissary, D'Artaguette, built a 60-ton boat to carry trade merchandise along the gulf coast and to France.

In 1709 the first Spanish boat came to trade provisions, brandy and tobacco for skins and furs brought by the Indians and French trappers. Also, early that year, Ft. Mobile at Twenty-Seven Mile Bluff was flooded by the Mobile River. The Indians told the settlers that the river often flooded the site, so Bienville ordered a new fort built on higher ground nearer the mouth of the Mobile River, just above the bay. The move to the new site was completed in 1711.

During that time, M. La Vigne Boisin, a captain of St. Malo, arrived at Isle Dauphine, where he dropped anchor, then proceeded to Mobile to call on D'Artaguette and Bienville. After staying several days, he asked them to allow him to build a fort on Isle Dauphine. They were very pleased and he returned to Isle Dauphine and began construction at once. At this fort he had embrasures constructed to contain cannon, which secured the entrance to the harbor.

He also had a very pretty church built. The front of the church faced the harbor where the ships were, and people from the ships could come in and hear mass. Some of the inhabitants of the fort at Twenty-Seven-Mile Bluff came to Isle Dauphine to settle, rather than to the new fort at Mobile. Something of a little town developed, and some people coming in from France settled there.
