But McKenna's careful reading of Clark's diaries, and of correspondence between Clark and Dymphna, demonstrate that it was impossible for Clark to have been in Bonn on the morning of November 10, 1938.In fact, it was Dymphna who witnessed the immediate aftermath of Kristallnacht, and it was in Dymphna's letters to Clark, who was not in continental Europe at all but in Oxford, that described the carnage that she had seen. In one of her letters to her wayward husband, Dymphna included an article about the event by Joseph Goebbels to which, years later, Clark referred in his claim to be present in Bonn on November 10, 1938. As Clark's own diary confirms, he did not arrive in Bonn until November 26 -- more than two weeks after Kristallnacht.
