The British Official Historian, L. F. Ellis, described the 22nd Armoured Brigade group withdrawal and explained that with the unexpected arrival of the 2nd Panzer Division, the 7th Armoured Division "could hardly have achieved full success". This view was partially supported by the briefing given to 7th Armoured Division commanders prior to the retreat but has gained little support. In 1979, following the revelation of Ultra, it was revealed that intercepted German communications revealed the 2nd Panzer Division to be from the front line on 12 June. Ralph Bennett called Montgomery's claim that the division "suddenly appeared", disingenuous. Buckley wrote that the order to retreat was given before the 2nd Panzer division arrived in any real strength and Reynolds wrote that "2nd Panzer's tanks were nowhere near Villers-Bocage at this time". Ellis described the retirement as temporary, the 7th Armoured Division was to be reinforced with the 33rd Armoured Brigade to renew the offensive towards Évrecy.
