His grave bears a one-word epitaph: Undefeated. It is understood that after the war, Hans-Joachim Marseille's remains were brought from Derna and reinterred in the memorial gardens at Tobruk; it was there that his mother visited his grave in 1954. His remains are now in a small clay coffin (sarcophagus) bearing the number 4133.
