Both Horia Sima and Ion Antonescu were invited by the German government to Obersalzberg to meet with Adolf Hitler in order to mediate relations between the two Romanian leaders and to discuss German-Romanian relations. Sima refused to attend the meeting, citing both apprehension regarding the flight and that he felt it improper for both leaders to leave the country. Thus, Antonescu met with Hitler alone on 14 January 1941. By 17 January, encouraged by Hitler, relations between Antonescu and Sima ceased to exist, and the General had published an open letter denouncing Sima and accusing him of maintaining an "anti-national attitude".
