Nanclares de Oca

Nanclares de Oca is an Álava prison camp that links the aftermath of the Spanish Civil War to the clandestine aid given to German fugitives in postwar Spain. Built by Republican prisoners and later used chiefly to hold international volunteers, it becomes a crucial point in Manuel Arroyo Benítez’s investigation when testimony reveals that a powerful visitor entered freely, supplied German prisoners, and handled their correspondence.

The camp and its changing population

The camp had first been built by Republican prisoners, but its principal use became the detention of international volunteers. That history gave Nanclares de Oca an earlier population of foreign prisoners before it received Germans who crossed the Pyrenees after the liberation of France. At first, the newcomers were mostly ordinary soldiers seeking to escape reprisals by the Resistance. As German surrender approached, however, the character of those entering Spain began to change: other kinds of fugitives followed the rank-and-file men.

The contrast between the camp’s original construction and its later use gives the site a layered political history. A place built by prisoners of the Republic became a holding site for people fleeing the consequences of Nazi defeat, while the treatment of its German inmates differed markedly from that of other detainees.

Testimony reveals an aid operation

The camp enters Arroyo’s inquiry through the account of Sole Ruiz, who had worked as a maid for Clarita Stauffer since the summer of 1943. By spring 1945, Sole knew the household’s routines well enough to notice a sudden change: Stauffer, who had previously rarely left Madrid, began making frequent trips north, sometimes spending two or three days away each week. Sole inferred the direction from the clothes packed in the suitcase and a passing remark about the cold, but did not initially know who received the blankets and provisions filling the car.

A conversation with the chauffeur supplied the missing place-name. Stauffer, he said, visited Germans imprisoned in a town in Álava; a later conversation over coffee established that the town was Nanclares de Oca. The information came not from an official record but from household knowledge—the movement of luggage, travel routines, and a servant’s access to domestic conversation.

Further testimony from international volunteers who had been held at the camp corroborated Sole’s account. They remembered a woman of about forty who came and went at will, acting as interpreter for the Nazis. She brought them clothes and food and collected and delivered their letters. The German prisoners were housed in barracks apart from the others and lived in considerably better conditions, which the witnesses connected to the influence of the woman who visited them.

From local evidence to a wider network

For Arroyo and his Republican associates, the reports from Nanclares de Oca turn a suspected pattern into a traceable operation. Sole’s observations establish Stauffer’s frequent journeys and the supplies she carried; the former prisoners’ memories add the practical services she provided inside the camp. Together, these details suggest organized assistance rather than occasional charity, and make the camp a key lead in understanding how fugitives were supported after crossing into Spain.

The evidence also distinguishes the German prisoners at Nanclares de Oca from prominent collaborators who entered Spain by other means. Léon Degrelle and Pierre Laval, for example, arrived by plane with recommendations from the minister Lequerica and the Spanish government’s approval; they did not pass through the camp. Nanclares de Oca instead held many other Nazis and collaborators from across Europe, making it one part of a broader system whose members did not all travel by the same route or receive the same kind of protection.

Narrative significance

Nanclares de Oca is more than a point on a map in Arroyo’s investigation. Its history as a camp for foreign prisoners, the preferential conditions enjoyed by the German detainees, and the repeated visits by a well-connected interpreter together show how an institution of confinement could also become a site of clandestine support. The camp’s importance is revealed through accumulated testimony: a servant notices changes at home, a chauffeur identifies the destination, and former prisoners describe what happened behind the camp’s walls. Their separate observations converge on the same place and help expose the assistance network operating around it.
