After Greenline the division was rapidly switched west for Operation Bluecoat, the attack on Caumont-sur-Orne, beginning on 30 July. This allowed the artillery little time to plan, and to preserve secrecy there was no preliminary bombardment. 181st Field Rgt married up as usual with 44th (Lowland) Bde, its observation posts (OPs) accompanying the infantry; the field regiments also had OPs in tanks with the supporting 6th Guards Tank Brigade. 15th (Scottish) Division's artillery including 181 Fd Rgt was tasked with firing concentrations in support of the attacking troops in Phase I. For Phase II a 110-minute slow barrage was fired. Three-quarters of the 25-pdr rounds were fuzed to Air burst, which was effective over bocage and allowed the tanks to keep close to the barrage in safety. The division's objective was Point 309 ('Quarry Hill') to protect the flank of the attack. Launched on 30 July the attack made good progress, with 15th (S) Division getting onto the Estry and Perrier Ridges to support the advancing armour. Heavy fighting ensued for several days, 15th (S) Division supporting  43rd (Wessex) Division's seizure of Mont Pinçon on 6 August. By 11 August 181 Fd Regt had reached  Monchamp near Caen. On 13 August the Germans began to withdraw and 15th (S) Division was relieved and went for its first rest since the landings.
