[724] I have come upon an interesting item in the history of the art of war in connection with this siege of Havre. In January, 1563, a Corsican, resident in Spain, by the name of Pietro Paolo del Delfino offered his services to St. Sulpice. “Il va dans l’eau,” wrote the ambassador to Catherine, “et m’a assuré qu’avec certains engins il empéchera que nul navire venant d’Angleterre puisse aborder aud. Havre sans grand danger.” In June Delfino arrived at Bois de Vincennes, where he was well received, according to his own statement (L’Ambassade de St. Sulpice, 112, and n. 4). But I do not find any further mention of him. Was this invention a sort of torpedo? We know that shells were first used in the siege of Orleans in this year.

In Appendix VI is a letter of Admiral Clinton to Lord Burghley, July 31, 1563, in which he says that the plague, not the arms of France, has conquered them.
