All troops north of the Somme were upon March 25 transferred to the Fifth Corps, and became part of the Third Army. The 27th Brigade was drawn out of the line, and the 26th was under the orders of the {124} Thirty-fifth Division which took over the defence of this sector, relieving the exhausted Twenty-first Division. March 25 saw heavy attacks on Bernafoy which was lost once, but regained by the 106th Brigade. There was still a gap to the north, and no touch had been made with the Seventeenth Division, though the cavalry had built up a defensive flank in that direction. At 2 P.M. the Germans attacked from Ginchy towards Trones Wood, names which we hoped had passed for ever from our war maps. In the first onset they pressed back the 12th and 18th Highland Light Infantry of the 106th Brigade, but there was a strong counter-attack headed by the 9th Durhams which retook Favière Wood and restored the situation. A second attack about 3 P.M. upon the Thirty-fifth Division was also repulsed. The German pressure was so great, however, that the line of defence was taken back during the night to the Bray-Albert position. The enemy followed closely at the heels of the rearguards, though the guns were active to the last so as to conceal the retreat as long as possible. Early in the morning of March 26 the Lowland Brigade was again attacked with great violence, but the 12th Royal Scots, upon whom the main assault fell, drove it back with loss. Changes in other parts of the line, however, necessitated a withdrawal across the Ancre, so as to keep in touch with the Twelfth Division which had now come up on the left. The Ninth Division upon this date numbered 1540 rifles with 20 machine-guns. It was shortly afterwards drawn from the line after as severe a spell of service as troops could possibly endure. The story of the retreat of the Seventh Corps has been indicated mainly from the point of view of this {125} northern unit, but it will be understood that the Twenty-first, as tried and as worn as its Scottish neighbour, was keeping its relative position to the south, while the Sixteenth was conforming in the same way until the time when it passed into the Nineteenth Corps.
