On the strength of this, it is thought likely that Cartier, returning safely to France in the summer of 1542, was sent back again at the king's command to aid in the return of the colonists, whose enterprise was recognized as a failure.

After this, Roberval is lost to sight in the history of France.

Certain chroniclers have said that he made another voyage to the New World and perished at sea.

Others have it that he was assassinated in Paris near the church of the Holy Innocents.

But nothing is known.
Cartier also is practically lost from sight during the last fifteen years of his life.
