The Battalion’s departure from the B1 Sub-sector was the result of a rearrangement of divisional fronts. The 46th Division was extending north and taking over the whole of the 147th Infantry Brigade sector, while the 49th Division was doing the same on its left. Hence, when the Battalion was relieved on January 30th, and moved to Humbercamps, it knew that it was not to return. [Illustration: Brig.-Genl. R. E. SUGDEN, C.M.G., D.S.O., T.D.] (_e_) Riviére. On February 1st the Battalion moved to Riviére, where it relieved the 8th Battalion King’s Royal Rifle Corps, in Brigade Reserve to the F1 Sub-sector. The 1/5th Battalion Duke of Wellington’s Regt. followed, and, throughout the next month, the two were inter-relieving as they had been at Berles. The accommodation in brigade reserve was very good, considering its nearness to the line. Three companies lived in billets in the village; the fourth garrisoned the Wailly Keeps, a reserve line of platoon posts. This latter was an ideal duty for an enthusiastic platoon commander. He had his own little command, nicely compact; he lived with his platoon, looked after its food, and supervised its work and training; and, except in one case, his company commander was not too near. What could a keen young subaltern want better? The bulk of the Battalion in Riviére found working parties, so there was little chance for training. But the Battalion had a tour in the line to do before it was really able to taste the joys of brigade reserve. On February 2nd it took over the F1 Sub-sector from the 7th Battalion King’s Royal Rifle Corps.
