Indeed after several stops in Aden, the French commercial vessels guided by Arab pilots from the Red Sea were heading towards the Gulf of Tadjourah. On January 3, 1710, passing between the island of Moucha and the coast of Tadjourah, they entered the "Society for Colonial and Maritime Studies, article 2, 1876 75 Tadjoura Bay. A large boat aboard which was an envoy of the Sultan of Tadjoura, Mohamed Dini was going ahead of them. This emissary sent them the letter of protection, in the name of the king of Adal and Zeyla: "We let you know that you have security and guarantee entirely in this port of Tadjourah to make water and wood, and we will give you a raban to introduce you to the city where you wish to stay. If you want to go to the port of Zeila it is the closest to the point where you were currently. We are people of good faith and we believe in God and his prophet. You have the safety of God and the safety of Sultan Mohamed, son of Sultan Dini”, on January 6, 1710, the commercial friendship treaty was signed between Sultan Mahammad Dini and Captain De La Merveille, commander of the French ships. The sultan undertakes to have the coffee imported from Ethiopia stored in Tadjoura with camels and to sell it only to the French¹¹. The captain of the Merveille undertakes for his part to pay 3% of customs duties on all goods purchased and embarked at the port of Tadjourah”.
