Philipp Freiherr von Boeselager (6 September 1917 – 1 May 2008) was the second-last surviving member of the 20 July Plot, a conspiracy of Wehrmacht officers to assassinate the German dictator Adolf Hitler in 1944.

Boeselager's role in the plan was to order his troops, who were unaware of the plot, to leave the front lines in Eastern Europe and to head west, where they would be airlifted to Berlin to seize crucial parts of the city in a full-scale coup d'état after Hitler had been killed.

Boeselager's opinion turned against the Nazi government in June 1942, after he received news that five Roma people had been shot in cold blood solely because of their ethnicity.

No longer caring about Himmler, the conspiracy planned to kill Hitler with a bomb when he was attending another strategy meeting in a wooden barracks.

When the assassin's bomb failed to kill the Führer, Boeselager was informed in time to turn his unexplained cavalry retreat around and return to the front before suspicions could be aroused.

[6] On 18 April 2008, just two weeks before his death, Philipp von Boeselager gave his last videotaped interview, which was conducted by Zora Wolter for the feature documentary The Valkyrie Legacy.

It was televised on The History Channel in spring 2009 to coincide with the release of the film Valkyrie, starring Tom Cruise and directed by Bryan Singer.

Albrecht von Boeselager (born 4 October 1949, Altenahr), former Grand Chancellor of the Sovereign Military Order of Malta, is their child.
