Mohnhaupt was first a member of the
Socialist Patients' Collective, known by its German acronym, SPK. Together with fellow commune member
Irmgard Möller, she joined the
Red Army Faction (RAF) around 1971 after the SPK dissolved, and helped with organization,
logistics, and weapon procurement. Below is a
timeline of Mohnhaupt's major acts as a
member of the RAF. • 9 June 1972: Mohnhaupt was arrested in
Berlin in connection with the RAF and sentenced to prison for involvement with a
criminal organization,
identity document forgery, and illegal weapon possession. • Shortly after
Ulrike Meinhof's death in prison in 1976, Mohnhaupt was, on her own request, transferred to
Stammheim Prison where the majority of other RAF prisoners were held captive. In Stammheim Prison she met
Gudrun Ensslin,
Andreas Baader, and
Jan-Carl Raspe, and was reportedly trained by them to become a leader of the RAF. • She was released on 8 February 1977, and immediately went underground and continued her work with the RAF. • Mohnhaupt was a major player in the
German Autumn: she was involved in the 1977 assassinations of chief federal prosecutor
Siegfried Buback in
Karlsruhe and banker
Jürgen Ponto, chairman of the
Dresdner Bank board of directors, in
Oberursel,
Taunus. She was also involved in the kidnapping and murder of employer representative
Hanns Martin Schleyer. • 11 May 1978 Mohnhaupt,
Sieglinde Hofmann,
Rolf Clemens Wagner, and
Peter-Jürgen Boock were arrested in
Zagreb,
Yugoslavia. • 17 November 1978 – Mohnhaupt and three other RAF members were allowed to leave Yugoslavia for a country of their choice because West Germany turned down an offer from Yugoslavia to extradite them in exchange for eight Croatian political fugitives in West Germany. • 15 September 1981 Mohnhaupt took part in an
assassination attempt on
U.S. General Frederick Kroesen using an
RPG-7 anti-tank rocket. ==Arrest and imprisonment==
