Fritz Knöchlein

Upon being found guilty, Knöchlein asked for leniency, saying he had a wife and four children, who depended on him. He was sentenced to death, and hanged at Hamelin Prison on 21 January 1949.

In August 1948, Knöchlein was formally charged with committing a war crime, to which he pleaded not guilty.

His trial began on Monday 11 October 1948 in Rotherbaum, and both Albert Pooley and William O'Callaghan were called to testify against him. Knöchlein's defence attorney claimed that Knöchlein had not been present on the day of the battle, and that the British forces had used illegal dum-dum bullets during the battle.

In 1942, the bodies were exhumed by the French authorities and reburied in a local cemetery, which eventually became the Le Paradis War Cemetery. Albert Pooley, who was subsequently taken prisoner along with O'Callaghan, made it a personal mission to hunt down Knöchlein and have him charged for war crimes. His story was confirmed when O'Callaghan was freed in 1945.

It was in his capacity as a company commander that he gained notoriety, being responsible for the 27 May 1940 massacre of British prisoners-of-war at Le Paradis in the Pas-de-Calais. Ninety-nine members of the 2nd Battalion of the Royal Norfolk Regiment, who had surrendered to his unit in a cattle shed, were stood in front of the barn wall, and Knöchlein ordered two machine-guns turned on them, followed by bayoneting and shooting any apparent survivors. Two of the prisoners, privates Albert Pooley and William O'Callaghan, managed to escape the massacre, but the remaining 97 were hastily buried along the barn wall. According to the historians Williamson Murray and Allan Millet: "The company commander, Hauptsturmführer (Captain) Fritz Knochlein, lined the prisoners up against a barn wall and machinegunned the lot. Any survivors were bayoneted and shot. German military authorities brought no charges against Knochlein."

Fritz Knöchlein (27 May 1911 – 21 January 1949) was an SS commander during the Nazi era who was convicted and executed in 1949 for committing war crimes during World War II, specifically for his responsibility for the Le Paradis massacre.
