Blockade of La Rochelle (1625)
Razilly participated to the Blockade of La Rochelle, where he commanded the blockade fleet, and lost an eye there.
Soon after, in 1626, he wrote pamphlets advocating commercial expansion overseas, either in Africa, Asia or America, such as his Articles pour persuader un chacun de risquer sur mer et trouver fonds pour la navigation. He submitted the memorandum to Cardinal Richelieu.
