Breville served as a German base from which to launch attacks against the British 6th Airborne Division whose paratroopers held a thin line and therefore could not defend well. So headquarters attached the 5th Black Watch Battalion to the 3rd Parachute Brigade to put an end to the German aggressions. The Highlanders arrived very early on the 11th and moved forward covered by a heavy artillery barrage.

The Highlanders encountered few problems until the barrage lifted as they neared Breville. The Germans then began to concentrate heavy fire on them, which quickly sent the Highlanders reeling backwards to Chateau St. Come with 300 casualties. The supporting 3rd Paratroopers Brigade contented themselves with firing their artillery in support and mentioning in their diary that the 5th Black Watch attack failed.
