With the weather improving over the United Kingdom and Normandy, Hausser's preparations for his counter stroke came under continual harassment from Allied aircraft and artillery fire, delaying the start of the attack to the afternoon. From the number of German reinforcements arriving in the VIII Corps sector and aerial reconnaissance, O'Connor suspected that the Germans were organising a counter-stroke. XXX Corps was still some way to the north, leaving the VIII Corps right flank vulnerable, O'Connor postponed attacks by I Corps and ordered VIII Corps onto the defensive. Dempsey, privy to ULTRA decrypts of intercepted German signal traffic, knew the counter-attack was coming and approved O'Connor's precautions. VIII Corps began to reorganise to meet the attack. Supply echelons for Hausser's divisions were located in the Évrecy–Noyers-Bocage–Villers-Bocage area and were the focus of RAF fighter-bomber attention throughout the morning and early afternoon; the RAF claimed the destruction of over 200 vehicles.
