[1] While working at a bookshop during 1941 and 1942, Buch became acquainted with Wilhelm Guddorf, through whom she became involved with the Red Orchestra.

Buch was charged and her case heard at the Reichskriegsgericht (Reich Military Tribunal) between February 1–3, 1943.

The primary evidence given against her was an article meant for slave labourers working in munition factories that she had translated into French.

The Catholic Church in Germany included Eva-Maria Buch in the martyrology of the 20th century.

[6] Eva-Maria Buch is remembered in Berlin by a memorial stone at Unter den Linden 6 and a plaque near St. Hedwig's Cathedral.
