Saint-Malo was also an active privateer port, specializing in naval warfare against English and Dutch vessels that crossed the Channel. While the French East Indies Company was being founded in 1664, and again after the inauguration of the French port of Lorient, the Saint-Malo shipowners armed their merchant ships to ensure the protection of the royal fleet. At sea, they were feared by all crews. In 1693, being unable to defeat the Saint-Malo privateers at sea, the English decided to destroy the port of Saint-Malo. Towards the end of the 17th century, the Saint-Malo sailors began to take an interest in trade in the southern seas: Jacques Gouin de Beauchêne, captain of the Phelypeaux, sailed in the Strait of Magellan in 1699. The expedition of Alain Porée, Joseph Trublet and Jean-Baptiste Bécard left Saint-Malo on August 25, 1703, destined for the Spanish colonies in South America and was the first French expedition to pass Cape Horn in the opposite direction, from east to west. These great expeditions also led to the attack on Rio de Janeiro in 1711 by the squadron of Duguay-Trouin, and the Moka expedition, which returned with precious coffee from Yemen. The great shipowners of the city, Noël Danycan, François-Auguste Magon de la Lande or Luc Magon de la Balue were joined by the Irish privateer Phillip Walsh, whose sons settled in Nantes where they founded the Antoine Walsh dynasty, specializing in the slave trade.
