Another had formed farther north. The Seventeenth Division, who were on the right of the Fifth Corps, held from Mametz to Contalmaison. Thence to Pozières was held by the Forty-seventh. A gap existed, however, upon their left, between them and the Sixty-third Division, who were gradually falling back upon Courcelette. The left of the Naval Division was also in the air, having lost touch with the right of the Second Division who were covering Le Sars. North of them the Nineteenth Division extended from the west of Grevillers to the south of Bihucourt. The 57th Brigade in the north, under the local command of Colonel Sole, fought a fine rearguard action as the enemy tried to debouch from Grevillers. Considering how terribly mauled this brigade had been a few days before, this was a really splendid performance of these brave Midlanders, and was repeated by them more than once during the day. From their left flank to the north stretched a new division, Braithwaite's Sixty-second, which had upheld the honour of Yorkshire so gloriously at Cambrai. Their line ran west of Sapignies and joined the Forty-second Division at the point where they touched the Sixth Corps, east of Ervillers. The front of the Sixty-second stretched from Bucquoy to Puisieux. The enemy kept working round the right flank, and the situation there was very dangerous, for everything to the immediate south was in a state of flux, shreds and patches of units endeavouring to cover a considerable stretch of all-important country. South of Puisieux there was a gap of four or five miles before one came to {64} British troops. Into this gap in the very nick of time came first the 4th Brigade of the Second Australian Division, and later the New Zealand Division in driblets, which gradually spanned the vacant space. It was a very close call for a break through without opposition. Being disappointed in this the Germans upon March 26 spent the whole afternoon in fierce attacks upon the Sixty-second Division, but got little but hard knocks from Braithwaite's Yorkshiremen. The 186th Brigade on the right threw back a flank to Rossignol Wood to cover the weak side.
