Advance parties departed to Normandy on D + 10 (16 June) but the entire brigade was not gathered together in France until early July 1944. Its first combat was in support of the 15th (Scottish) Infantry Division in Operation Greenline from 15 to 18 July, to enlarge the Odon bridgehead and advance beyond Hill 112; the German opposition held a strong position and 153rd Regiment Royal Armoured Corps suffered particularly severe casualties, including its commanding officer. Overall, the brigade lost 30 officers and 156 other ranks in this action. The brigade continued in active service in Normandy until late August.
