David French wrote that the follow-up formations landing in Normandy were on average two days behind schedule and that had the 33rd Armoured Brigade, the 49th (West Riding) Infantry Division and the 7th Armoured Division's infantry brigade landed on time, XXX Corps might have been able to secure Villers-Bocage, before the arrival of substantial German forces. Other historians wrote that substantial British forces remained uncommitted during the battle. Mungo Melvin wrote that although the 7th Armoured Division changed its organisation to a flexible combined arms structure, which was not done by the other British armoured divisions until after Operation Goodwood, neither the 131st Infantry Brigade nor the balanced divisional reserve of an armoured regiment and an infantry battalion were employed well.
