During this period the artillery carried out periodical bombardments of the enemy's trenches, with the idea of making him think that an attack in this sector was imminent. In this they seem to have been successful, for each night the Germans fired intermittent short hurricane bombardments on the front and support and communication trenches, presumably with a view to preventing the assembly of attacking troops. These bombardments were extremely heavy while they lasted; but, thanks to the large number of dug-outs which had by this time been completed, they inflicted little loss on the trench garrisons. On 27th June arrangements were begun for the attachment of the 60th (2nd Line London Territorial) Division to the Highland Division for a period of instruction in the line. The news of the arrival of the 60th Division was welcomed by all ranks, as it was looked on as a sure indication that the Division would be relieved and would move to the Somme battle. It had been arranged that as soon as the 60th Division were ready to take over the line, the Highland Division should be moved to the back areas for a period of much-needed rest and training before proceeding southwards. Possibly, with its later experiences of battle fighting the Division might not have been so anxious to hurry off to take part in a great attack. In these days, however, apart from the battle of Festubert, it had not been employed in an offensive. Officers and men were therefore anxious that the Division should be given an opportunity of operating in an attack as a complete unit. The 60th Division began their attachment on 30th June. This was carried out first by individual officers and N.C.O.'s, then by sections, by platoons, by companies, and finally by battalions. On 13th July the brigades of the 60th Division began taking over from the brigades of the Highland Division. On 14th July General Bultin, G.O.C. 60th Division, assumed command of the sector. This system of instruction meant that there were reliefs of some kind being carried out every night. These were greatly hampered by the sudden intense bombardments to which the enemy subjected the British trenches. In consequence, casualties were frequently heavy. In one brigade sector alone over sixty casualties were sustained during a single night. As a parting gift to the Germans on the last day the Division was in the line, the 5th Gordon Highlanders raided the enemy's trenches, bombed his dug-outs, and killed several of the garrison. On 14th July the Division moved by motor lorry to the Doullens-Lucheux-Baudricourt area. The popular supposition amongst the troops was that they were bound for a rest area. On the 15th the move was continued by march south to the area Bernaville-Candas-Hem.
