Abwehr

The Abwehr was the common name for the German military foreign information and counterintelligence department, during both World War I and World War II.

The head of Abwehr during World War II was Admiral Wilhelm Canaris. Under his lead, the Abwehr became a center of conspiracy against the Nazi regime. Helped by Canaris' protection, one of his subordinates, Hans Oster[?], helped to organise internal opposition to the Nazis. Although in April 1943, many of Oster's co-conspirators were arrested and the Abwehr was put under constant surveillance, Canaris was dismissed in February of 1944.
