In early June Wavell sent a force under General Wilson to invade Syria and Lebanon, responding to the help given by the Vichy France authorities there to the Iraq Government during the Anglo-Iraqi War. Initial hopes of a quick victory faded as the French put up a determined defence. Churchill determined to relieve Wavell and after the failure in mid June of Operation Battleaxe, intended to relieve Tobruk, he told Wavell on 20 June that he was to be replaced by Auchinleck, whose attitude during the Iraq crisis had impressed him. Rommel rated Wavell highly, despite Wavell's lack of success against him.
