Antionio's son Thomas took over as governor of the Bastion in 1597. but the prosperity of the Lenches was threatened by the warlike politics of North Africa. In June 1604, the Bastion de France was destroyed by the militia of Annaba, supported by galleys from Rais Murad of Algiers. The Lenches appealed for help to
Henri IV who protested through his consul in Algiers, M. de Vias. In response the consul was severely beaten, but eventually Thomas was able to secure the return of his privileges. In 1602 the Bastion de France was visited in the name of King
Henri IV by Charles of Lorraine, Duc de Guise, confirming the French presence. However, in 1604, following further intrigues and disputes, the Bastion was once again seized and destroyed. France retained sufficient influence in Istanbul to secure the dismissal of the Dey of Algiers for this outrage, who was then strangled. In 1608 Algiers made a new contract favouring merchants from Bordeaux, which was seeking to oust Marseille from its preeminent position in the luxury trades, and push the Lenche family out of their foothold. In 1619, exhausted by this constant destruction, Thomas II Lenche sold his rights over the Bastion to the duc de Guise, governor of Provence, in exchange for an annual pension of 4,800
livres tournois. ==Sanson Napollon==
