Also in 1967, Irving published two more works: "The Virus House", an account of the German nuclear energy project for which Irving conducted many interviews, and "The Destruction of Convoy PQ-17," in which he blamed British escort group commander Commander Jack Broome for the catastrophic losses of the Convoy PQ 17. Amid much publicity, Broome sued Irving for libel in October 1968, and in February 1970, after a 17-day-trial before London's High Court, Broome won. Irving was forced to pay £40,000 in damages, and the book was withdrawn from circulation.
