One could not fail to appreciate the diabolical efficiency with which the work had been carried out. Where time had been too short to enable fruit-trees to be felled, their bark had been ringed. Wells before destruction had been turned into cess-pits. The effect on every unit on first entering the devastated area was the same. It produced a determination in all ranks to kill every German that it was possible to put out of the world with any degree of decency. By this wanton act of vandalism the Hun had turned himself, in the eyes of the British soldier, into a vermin fit only for extermination. "Our new positions" mentioned above were the Hindenburg Line. The Hindenburg Line was not a line in the true sense of the word, since, in addition to having length, it also had considerable breadth. It was, in fact, a highly-elaborated system of trenches running roughly from St. Quentin to just south of Arras. The trenches were skilfully sited, so as to have every advantage of observation; they were of immense breadth and depth; they contained numerous concrete machine-gun emplacements and dug-outs; they were connected with one another by underground tunnels; they were protected by tremendous belts of wire many yards in depth. Yet, in spite of the skill with which it had been constructed, several portions of the Hindenburg Line were twice captured by the British army. From this point onwards the Highland Division was so continuously involved in important operations that space cannot be given to detailed accounts of uneventful periods in quiet parts of the line. It must, however, be understood that uneventful is a relative term, and that even the quiet periods were often eventful enough for those in immediate contact with the enemy. As regards the sojourn in the Boisleux au Mont area, suffice it to say that all three brigades carried out tours of duty in the line there, and that the Division was relieved on 2nd November. On completion of this relief the Division moved to Hermaville, the infantry brigades being billeted at Warlus, Hautvillers, and Izel les Hameaux. Prior to taking over the line in this sector a change in command had taken place in the 154th Brigade. Brigadier-General J. G. H. Hamilton, D.S.O., who had commanded the brigade since General Stewart's death in September 1916, gave up his command, and returned home for a period of rest. General Hamilton had come to the brigade from the command of a battalion, and had been with it through many trying ordeals, including Beaumont Hamel, Courcelette, Arras, and Ypres. By many of his officers, both senior and junior, he was regarded not only as their brigade commander, but also as an intimate friend, and his departure was in consequence keenly felt.
