This article is in today's Daily Torygraph. There is evidently a new limited release book detailing SAS actions in the early period of that regiment's existence. The primary source is the SAS's own mission notes/records.
At the start of the article is an account of an attack on a company sized unit of SS in a village called Les Ormes near Auxerre in France. This SS unit were about to conduct executions of civilians in reprisal for an earlier SAS attack. The SAS patrol - two jeeps in total - so no more than 6 or 8 men, launched a frontal attack with no preparation, inflicting 70 casaulties for 1 casaulty of their own.
