In 1955, Barnes first met David Hoggan , and played a key role in helping Hoggan adapt his 1948 PhD dissertation, The Breakdown of German-Polish Relations in 1939: The Conflict Between the German New Order and the Polish Idea of Central Eastern Europe, into his 1961 book, Der erzwungene Krieg ( The Forced War ). It was "based on, but quite different from, the dissertation", and Hoggan blamed Britain and Poland for World War II.  In 1963, Barnes self-published a pamphlet, "Blasting the Historical Black-out", in which he offered some praise for A. J. P. Taylor's 1961 book, The Origins of the Second World War .  Barnes said that he thought Hoggan's book was better than Taylor's.  In "Blasting the Historical Black-out", Barnes referred to the "alleged wartime crimes of Germany" and wrote that, "Even assuming that all the charges ever made by the Nazis by anybody of reasonable sanity and responsibility are true, the Allies did not come off much, if any better".  Barnes wrote further that the suffering by ethnic Germans expelled from Czechoslovakia and Poland after World War II were "obviously far more hideous and prolonged than those of the Jews said to have been exterminated in great numbers by the Nazis."
