to get through the British artillery-fire, taking post in Round Wood, where it was able to repulse the 64th Brigade. The rest of the regimental reserves were used to block the route to Contalmaison. The loss of Mametz and the advance of the 21st Division made Fricourt untenable and the garrison was withdrawn during the night. The 17th Division occupied the village virtually unopposed early on 2 July and took several prisoners. The 21st Division suffered and the 50th Brigade of the 17th Division III Corps La Boisselle The 34th Division (New Army) was to attack along the Albert–Bapaume road, aided by the blowing of Lochnagar mine and Y Sap mine (the largest mine explosions of the day) either side of La Boisselle. The mine at Y Sap, north of the village, caused no casualties as the Germans had evacuated the area in time but the springing of the Lochnagar mine, south of the village, temporarily trapped German troops in shelters nearby and the position was lost.

Despite machine-gun fire, a party of around survived to advance up Sausage Valley, south of La Boisselle, almost to the edge of Contalmaison. The survivors were captured after making the furthest British advance of the day, about .
