High Quality Content by WIKIPEDIA articles! The Schwarze Kapelle were patriotic Germans, including many in the higher echelons of the Wehrmacht and Abwehr, who feared Hitler's policies would ruin the country; by overthrowing the Nazi Party they hoped to preserve German sovereignty. Through Admiral Canaris' Abwehr they were in touch with their counterparts in Britain and other Allied and neutral nations. Elements of the Schwarze Kapelle began making overtures to Britain before war broke out and while Hitler could have been easily ousted or killed. British officials said they would not interfere with German internal affairs at that time.

Making deals with any Germans was not going to be an easy matter.
