"The role that Rommel played in the military's resistance against Hitler or the 20 July plot is difficult to ascertain, as people most directly involved did not survive and limited documentation on the conspirators' plans and preparations exists.[259][260] The strongest evidence that points to the possibility that Rommel came to support the assassination plan was General Eberbach's confession to his son (eavesdropped by British agencies) while in British captivity, which stated that Rommel explicitly said to him that Hitler and his close associates had to be killed because this would be the only way out for Germany.[261][262][263] This conversation happened about a month before Rommel had to commit suicide."
"Before going to his death, Rommel denied involvement in the plot, declared his love for Hitler and that he would gladly serve his "Fatherland" again."
