In 1513, he helped the Count of Oliveto, Pedro Navarro, attack the port of Tripoli providing galleys from Sicily. In 1522, as a general for Charles V, Holy Roman Emperor, he besieges the battlements of Tournai. In 1524, with 16 galleys, he attacked and took the ramparts of Toulon, Hières and Frejus, but was defeated and captured by Andrea Doria at the mouth of the river Var. He was liberated in 1526 by the Treaty of Madrid. Under the terms of this Treaty, Moncada was exchanged for Montmorency. In June 1526, Moncada was sent by Emperor Charles V, as an ambassador to Pope Clement VII in Rome. Moncacda carried a message to the pope that should he ally with the French in the War of the League of Cambrai that Charles V would seek to turn the city-state of Siena in northern Italy against the Papal States and would also use his influence with the Colonna family to also turn this important Italian family against Pope Clement VII. Pope Clement recognized the potency of these two threats and as the French marched into Lombardy, Pope Clement withdrew all his forces back to Rome.
