[3] The King set up these estates in a area of France immediately bordering the English possessions of the Guyenne in the south west and in the north east, and was particularly exposed.

In 1340, Luis received a testimony of royal confidence when he was called on March 13 to fill the post of admiral left vacant by Hue Quiéret, fatally wounded in a naval battle.

To make the river crossing, Luis ordered rafts be built, but these preparations were moot, for at the end of four days, the defenders killed their own captain and opened the gates.

These chroniclers, state that one day in the tent of Charles de Blois, and in front of other lords, begged him to grant him a grace in reward for his services.

While Amaury de Clisson simulated a distraction to attract the attention of the besiegers, Mauny took a detour into the now empty camp and recaptured the two knights returning with them.

A storm that arose during the night forced the adversaries to part ways, but not before the Franco-Bretons had captured four Anglo-Breton ships loaded with provisions and horses.

Majorcan expeditions, organized by private commercial consortiums, set out immediately for the Canary islands, with the objective of capturing natives to sell them as slaves in European markets.

Luis de la Cerda, then serving as a French ambassador to the papal court in Avignon, submitted a proposal to Pope Clement VI that offered the Catholic Church the more palatable vision of conquering the islands and converting the native Guanches to Christianity.

[10] In return, Cerda promised to convert the natives and render the papacy an annual tribute of 400 gold florins, due yearly on the feast of Saints Peter and Paul (29 June).

[11] Eleven islands were cited in the bull by the ancient (and fantastical) names given by Pliny: Canaria, Ningaria, Plumaria, Capraria, Junonia, Embronea, Atlantica, Hesperida, Cernae, Gorgona and Galeta.

[12] Upon receiving the crown and sceptre from the hands of the pope, a cavalcade was sent around the streets of Avignon, announcing Luis de la Cerda as the newly created king of the islands.

Pope Clement VI followed this up with another bull, Prouenit ex tue in January 1345, giving the Cerda conquest the character of a crusade, granting indulgences to any who participated.

[16] Alfonso XI of Castile also protested, using the ancient Visigothic dioceses and prior reconquista treaties to claim the islands fell within Castilian jurisdiction and 'sphere of conquest', but nonetheless recognized Cerda's title.

With the assistance of the Archbishop of Neopatria, Luis de la Cerda managed to secure a commitment from Peter IV of Aragon to put some galleys at his disposal, but the others were far less forthcoming, if not outright hostile.

[18] The renewed outbreak of the Hundred Years War in 1346 put the project on hold, as Luis de la Cerda resumed military service for the French crown.

His titles of Talmont and Prince of Fortuna were inherited by his eldest living son Luis de la Cerda y Guzmán.

Although it is reported that the papal-conferred title of Prince of Fortuna automatically expired after five years with no expedition, the De la Cerda-Medinacelli family continued to press their claim for the lordship of the islands.

Offspring from this marriage: After his first wife's death, Luis de la Cerda married Guiote D'Uzès, daughter of Robert I, Viscount of Uzès.
