ONE of the famous
BJ's or "Black Jumbos", an illustration
from David Irving, Churchill¹s
War, vol. ii. The Japanese government
orders its embassies in enemy capitals to
destroy code materials; a message decoded
by the British on the eve of Pearl Harbor.
Mr Irving has made extensive analysis of
these for this work on the wartime British
prime minister, appearing later this year.
See especially chapters 10, 11 and 12.
