Caskie came under the suspicion of the Vichy France and German authorities, and a fellow Briton betrayed him. Pastor Heuzé was one of many to be executed. Lack of evidence saved Caskie’s life for the first time; instead he received a suspended prison sentence and was ordered to leave Marseilles. This was partly helped by Caskie’s ability to speak Gaelic, confounding his interrogators. Caskie headed for Grenoble, where he was employed by the university, and acted as a chaplain for interned British soldiers and resident civilians. The Germans later ordered that all British-born civilians in the occupied countries be interned in Germany; Caskie managed to influence an Italian commandant to release many of them. Caskie was arrested again and spent some time in Italian custody at Sanremo, held in the old fortess prison. Later in 1943 he was transferred back to German custody and eventually put on trial in Fresnes, and sentenced to death. Awaiting execution by firing squad, Caskie asked to see a pastor. This saved his life; the German army padre Hans Helmut Peters successfully appealed to Berlin to spare Caskie. He then spent the rest of the war in a Prisoner of War camp, resuming his ministry in Paris after the war.
Scots Kirk Church
had been unused throughout the war, and lack of maintenance led to the church having to be rebuilt during the 1950s. To help pay for the rebuilding, his autobiographical account of his extraordinary wartime activities was published as The Tartan Pimpernel in 1957. The 1950s building proved to have serious defects and had to be again rebuilt in the late 1990s, Caskie's book being again reissued.
Later life
Caskie finally returned to Scotland as minister in Old Gourock Church. In 1961 he became a minister at Wemyss Bay and Skelmorlie on the Firth of Clyde. He was the subject of This Is Your Life in September 1959 when he was surprised by Eamonn Andrews in the foyer of the BBC Television Theatre. He retired to Edinburgh in the early seventies and lived the final year of his life with his younger brother in Greenock. He died in 1983 and is buried at Bowmore on Islay. Various personal artefacts, including his wartime medals, can be seen at Kilarrow Parish Church, Bowmore.
Honours and awards
He was appointed an Officer of the Order of the British Empire in June 1945 for services to the Forces in France. He was honoured by the French government for his wartime service. The Alliance France-Ecosse society erected a memorial plaque at the rue de Forbin in Marseille, France. On 26 October 2019 a memorial plaque marking his work was unveiled at the Fort de la Revere near Nice by the Le Devoir du Memoire organisation, which honours those affected by the war, including Resistance fighters.
