Orders were now received from the French Corps that the Scots Fifteenth Division should change place with its neighbour, the Eighty-seventh French Division, a difficult operation which was successfully accomplished, the artillery in each case being left in position. The new operation was to consist of an attack upon Hartennes Forest, the Twelfth French Division working round the south and the Fifteenth Scots Division round the north end of it, both meeting to the east, with Droisy as an ultimate objective. The attacking troops were concealed so far as possible in the cornfields on July 31, and went forward about eight o'clock in the morning of August 1, after the completion of a successful French advance further down the line. The brunt of this new advance was borne by the 6th Camerons and 13th Royal Scots of the 45th Brigade (Orr-Ewing), together with the 10th Scots Rifles and 7/8th Scottish Borderers of the 46th Brigade (Fortune). The left of the line made fine progress and reached the east side of the Soissons Road, but the 45th Brigade on the right was held up by terrible machine-gun fire, part of which came from several derelict French tanks. These were dealt with and blown to pieces by trench mortars. The advance was then resumed, the French Twelfth Division coming forward also in the south. About midday the Camerons had reached their mark, but were out of touch with the Borderers on their right, so that they were compelled to form a defensive flank from the cemetery to the road. The Germans lay in a series of wooded hills upon the right, and though these were smothered with shells the brave machine-gunners {17} still clung to their position. So heavy was their fire that the right flank could get no farther, and it was determined to hold on to the ground gained. During the night the 44th Brigade, in spite of its heavy losses three days before, took the place of the 46th. [Sidenote: Fifteenth Division at Buzancy. July 28-August 2.]
