On the 10th August, 1916, the Battalion entrained at Godewaersvelde, and detraining at Candas, marched to Heuzecourt and spent four days resting. The 15th, 16th and 17th were spent in marching through Vignacourt and Villers Bocage to Baizieux, where the men bivouaced in the wood. Here two accidents occurred. Major F. Walton, Second in Command, and Lieut. Ebsworth, M.C., Adjutant, were thrown from their horses and sustained broken limbs. 2nd Lieut. Kirkhouse resumed duties as Adjutant. Nearly a month was spent in the wood, the time being devoted to training in the new wave formation for the coming offensive. It was about this time that distinguishing marks were adopted in the Division and the Battalion began to wear the red diamonds which came to be regarded with almost as much pride as the cap badge, and continued to be worn as long as the Battalion existed as a unit in France. On the 6th September Brig.-Gen. N.J.G. Cameron took over command of the Brigade. Four days later the Battalion moved to bivouacs in Becourt Wood, and there the final preparations were made for action, and amid the growing violence of the artillery preparation it moved again on the 14th September to Shelter Wood. Zero for the second phase of the Somme battle was 6.20 a.m. on the 15th September. The 149th and 150th Infantry Brigades were then in the front line between High Wood and Martinpuich with the 151st Brigade in reserve. At zero the Battalion moved from Shelter Wood by way of Sausage Valley to an old German trench at the south-west corner of Mametz Wood. About noon a further forward move was made, Y and Z Companies to the northern edge of the wood, and W and X Companies to a position a little further forward between Mametz and Bazentin-le-Petit Woods. So far the Battalion had escaped shell fire, and the men were much interested in prisoners who were being escorted to the rear. About 11 a.m. a message was received that the 47th Division had failed to take High Wood, and that the two Brigades of the 50th Division had secured their objectives. Later came a message that the 47th Division had taken High Wood at the second attempt. Rations arrived about 5 p.m., and whilst they were being distributed Lieut.-Col. Jeffreys returned from Brigade Headquarters with orders to move up at once. Accordingly the Battalion paraded and marched up the road to the Quarry at Bazentin-le-Petit. By this time the area was full of movement. Guns, ammunition, ration wagons and troops were everywhere moving up after the advance.
