a car with Alfonso XIII was travelling from the Spanish border to Biarritz, while a car with Don Jaime was travelling South to Behovia; they met at a closed railway crossing near Urugne in France. While Don Jaime's entourage, including Rafael de Olazábal and Julio de Urquijo, rose to pay their respect to member of the royal family, Don Jaime kept sitting and stared at Alfonso XIII, who did not know the Carlist prince. The train passed in-between, the crossing was opened and two vehicles parted each its own way. Referred after La Correspondencia Militar 30.07.1908, available here

in a letter of January 1933 to Lorenzo Sáenz, Don Alfonso Carlos wrote: "El famoso pacto firmado el 12 de septiembre de 1932 [sic!] entre don Alfonso y Jaime, me lo envió don Alfonso al morir Jaime. Me quedé desconsolado al ver la firma de Jaime, pues está puesto en términos no tradicionalistas. Estaba dispuesto Jaime a reconocer por rey a don Alfonso, y volverse él infante si las Cortes ¡Constituyentes! lo deseaban. Don Alfonso deseaba tener mi firma, como va indicado en aquel pacto; yo me opuse absolutamente, pues soy tradicionalista decidido y antiliberal", quoted after José María Lamamie de Clairac, Negociaciones e intentos de pactos entre las dos ramas dinásticas, [in:] Informaciones 07.07.54, reproduced online here. It seems worth noting that in the summer of 1931, when the pact was being negotiated, the position of Alfonso Carlos seemed of little relevance; he was not expected to outlive Don Jaime and to assume the Carlist claim. Besides, since the late 1870s during 60 years he was scarcely engaged in Carlist politics and has never tried to influence his brother Carlos VII or his nephew Jaime III.
