When Otto Skorzeny (a Waffen-SS commando leader) was on trial for war crimes, Forest Frederick Edward Yeo-Thomas,
a RAF officer and SOE agent (known as 'the White Rabbit'), testified that he and his men sometimes had been wearing

"Skorzeny admitted to ordering his men to wear US uniforms, but his defence argued that as long as enemy uniforms
