As March 24 wore on the position of the Thirty-ninth Division became untenable, as they heard upon one side of the loss of Saillisel, and on the other of the forcing of the Somme at Brie, Pagny, and Bethencourt. They moved back, therefore, at night with orders to hold the line from Buscourt to Feuilleres. The average strength of brigades at this time was not more than 20 officers and 600 men. From the morning of March 25 the Thirty-ninth Division passed to the command of the Nineteenth Corps, and its {123} further arduous work will be found under that heading. During all this day Campbell's Twenty-first Division, still fighting hard in a succession of defensive positions, had its right upon the Somme, while its left was in intermittent touch with the Ninth Division. The Ninth Division had fallen back, the two Scottish brigades being continually in action until they reached the Maricourt-Montauban line, where they supported the First Cavalry Division who were in front of Bernafoy Wood. The general line at this period from Montauban southwards was held by the Ninth Division, the First Cavalry, the newly-arrived and most welcome Thirty-fifth Division (Franks), the Twenty-first Division, now reduced to a single composite brigade under General Headlam, and then some oddments under Colonel Hunt. This brought the line to the Somme, on the south side of which were the remains of the Sixteenth and Thirty-ninth Divisions. This might sound an imposing force upon so short a front, but save for the Thirty-fifth each division was _nominis magni umbra_, none of them stronger than brigades. The Forty-seventh Division was retiring at this time upon Contalmaison, and a gap of several miles was appearing between the Fifth and Seventh Corps. During the movements upon March 24 the guns of the 65th and 150th R.F.A. did great work and earned the warm gratitude of the weary infantry. The enemy targets round Combles were all that a gunner could wish.
