Boswell immediately set out to publish as many words as he was able, beginning with a letter in "Nature" dated 9 March 1935, destroying Reck's and Louis's dates of the fossils and questioning Louis's competence. Despite the searches for the iron markers, Boswell averred that "the earlier expedition (of 1931–32) neither marked the localities on the ground nor recorded the sites on a map." In a field report of March 1935, Louis accused Boswell of reneging on his word, but Boswell asserted he had made no such promise, and now having public opinion on his side, warned Louis to withdraw the claim. Louis was not only forced to retract the accusation in his final field report in June 1935, but also to recant his support of Reck. Louis was through at Cambridge. Even his mentors turned on him.
