1943, Scholl, Schmorell, and Graf snuck out and graffitied the Feldherrnhalle, then a Nazi monument to the Nazis who were killed during the failed Beer Hall Putsch. The graffiti campaigns put the Gestapo on high alert. Capture and Execution On 18 February 1943, Sophie and Hans Scholl went to the Ludwig Maximilian University to leave flyers out for the students to read. They were seen by Jakob Schmid, a custodian at the university who was also a Gestapo informer. At around midnight on 18 February, Gestapo agents arrested Graf when he returned to his apartment after meeting with his cousins. When he was captured, he asked to be allowed to go to his bedroom and change into his Wehrmacht uniform. The agents agreed to his request. While changing, he was able to hide his diary under his many books. The diary was later found by his sister Anneliese, who was also arrested by the Gestapo at the same time.

Eight schools in Germany have been named after him, among them the Willi-Graf-Gymnasium in Munich and Saarbrücken-St. Johann; a student residence in Munich also honours Graf by bearing his name. Graf's diary from 1942 to 1943, as well as his letters from that time, were published in 1988 under the title: Willi Graf:Briefe und Aufzeichnungen. In 2003, Graf was posthumously awarded the status of honorary citizen of Saarbrücken. The Catholic Church in Germany included Graf in their list of martyrs of the 20th century. In 2017, the Archbishop of Munich and Freising, Cardinal Reinhard Marx, initiated the first step in the process of beatification, a preliminary investigation in which theologians
