Captain B. W. Roscoe (later Major, D.S.O., 2nd I.C. 5th C.M.R. Battalion, wounded June 3, 1916, at Sanctuary Wood); 2nd I.C., Captain H. H. Pineo (later killed in action at Mt.

George Gill (later R.S.M. 5th C.M.R. Battalion); “B” Squadron was formed into “D” Company of the 4th C.M.R. Battalion, the company officers and warrant officers being: Major C. H. McLean (later 2nd I.C. 4th C.M.R. Battalion); Capt. M. A. Scovil; Lieut. George Morrisey. SANCTUARY WOOD. The first serious engagement in which the Brigade was concerned was the Battle of Sanctuary Wood, which began June 2, 1916. The disposition of the Brigade was: 1st and 4th C.M.R., front line and close support; 5th C.M.R., Battalion H.Q. and three Companies in support at Maple Copse; one Company in reserve at Zillebeke Bund; 2nd C.M.R. in Brigade reserve near Poperinghe. The morning of June 2nd was clear with good visibility. About 8 a.m. the Hun started a heavy bombardment, which grew in intensity, and information was received that an attack was in progress on the sector held by the 7th and 8th Brigades. The bombardment continued unabatingly, and about twelve o’clock mines were seen to be blown. The whole of the area held by the two Brigades was being systematically and furiously shelled, and communication with the forward area was impossible. About 2 p.m. Captain Roscoe received orders to reinforce with his Company, the remainder of the Battalion at Maple Copse. There was no route specified, the officer conveying the order remarking that he hoped they would get through. The only other officer with the Company at this time was Lieut. G. N. D. Otty, but it developed that the N.C.O.’s had the requisite requirements of leadership and judgment. The Company, led by Captain Roscoe, advanced to the support of the remainder of the Battalion, and in full view of the enemy, through an extremely heavy barrage of fire, reached Maple Copse with few casualties, reporting to Lieut.-Colonel G. H. Baker, then commanding the Battalion. Orders were then received to connect up with the 7th Brigade on the left, to dig in and hold the Copse to the last. Then it was that the N.C.O.’s showed those qualities of leadership and judgment, which later were to be recognized in a substantial manner.
