Friedrich Paulus
The German Armed Forces High Command ("Oberkommando der Wehrmacht") sent General Friedrich Paulus to Africa to investigate the situation. On 12 May General Paulus, after witnessing one of Rommel's failed attempts to assault Tobruk, sent a report to OKW describing Rommel's position as weak, with critical shortages of both fuel and ammunition. With Operation Barbarossa imminent, Field Marshal Walther von Brauchitsch, Commander-in-Chief of the German Army, ordered Rommel not to advance further or attack Tobruk again.
