This is recounted in the article:
> Karsh ducked his head under the camera’s viewing cloth and adjusted the focus. The cigar was still lit in Churchill’s mouth. In a tale that he would repeat countless times, Karsh suggested the prime minister place the cigar in a nearby ashtray. Churchill ignored him, so Karsh pulled the cigar from his mouth and rushed back to his camera. “He looked so belligerent he could have devoured me,” Karsh later recalled. Then he pulled the trigger.
Ah. I scanned the article for mention of the story but missed that. My bad.
