On Friday evening, 3 July 1970, a Clarksons chartered Dan Air de Havilland Comet, registration G-APDN, en route from Manchester to Barcelona deviated from the intended course and crashed into high ground at Sierra del Montseny, Gerona, in northern Spain.
He was the son of Sunifred, the Vizconde de Gerona (Viscount of Gerona) who was granted the castle and lands of Moncada in Montcada i Reixac, Barcelona.
The viceroy of Catalonia, don Juan Manuel Lopez Pacheco Acuña Giron y Portocarrero, marquis of Villena duke of Escalona, who was also the Captain General of the army, had deployed along the banks of the river Ter practically all the marching troops he could muster to oppose the strong French expeditionary corps, led by the French Marshal duke of Noailles, who wanted to capture Gerona.
A Spanish solidarity association with the Sahrawi people from Palafrugell, Gerona, had named itself Lembarki in his memory.
He was captured by the Spanish Guardia Civil while crossing into Spain from Andorra, and was held in jail in Gerona until he was transferred to a concentration camp in Miranda de Ebro.
