Salt from the Atlantic Ocean was in the eighteenth century among the principal products transported on the rivers of the Loire and the Seine. It supplied the salt storehouses in these two river basins, starting with the entrepots located in Nantes and near Rouen. In addition, large quantities of salt were exported to Northern Europe. During the Napoleonic wars, the commerce of salt, like that of other products, was completely disrupted by the obstacles posed to cabotage. The salt intended for the Seine basin, for Belgium, Holland, and northern Germany was taken from the Loire, then the Seine and the Scheldt.With the fall of the Empire, this organization was called in question, and cabotage resumed. The brief golden age of salt on the Loire raises the question of the importance of the redeployment of transports towards the interior during the maritime wars.
