James Venture, one of the last survivors of the infamous Train de Loos, which carried French resistance fighters, Communists and Jews from a prison in the northern French village of Loos to concentration camps in Germany in September 1944, died on April 1 at his home in Mons-en-Baroeul, France, near Lille. He was 93.

His wife and only immediate survivor, Françoise, confirmed his death.

After World War II, Mr. Venture led an organization dedicated to ensuring that other survivors of the train would be cared for and that their experience would not be forgotten.

Believed to be the last of the wartime death trains from France, the Loos train carried 871 prisoners packed into a dozen cattle wagons. Some died on the train, some in the camps and some on “death marches” as the Nazis, nearing defeat, cleared the camps. Only about 275 survived the war.

Mr. Venture was a Lille police officer working secretly for the resistance. He and his comrades carried out sabotage operations in and around German-occupied Lille, including on a vital railway yard and locomotive works.
