Having been nominated Admiral of the fleet of La Rochelle, Jean Guiton fought the Naval battle of Saint-Martin-de-Ré against Royal forces on 27 October 1622.[1]
He later participated to the uprising of Soubise in 1625, leading to the Capture of Ré island by Royal forces that same year.
He became mayor of La Rochelle and, during the 1627-1628 Siege of La Rochelle, he organized an energetic resistance to the troops of king Louis XIII. The scene is still visible today in the City Hall (Hotel de Ville) of La Rochelle, where a marble table with a chip made by his dagger is on display.
