This knowledge enabled him, in conjunction with General Harper, to draw up the artillery plans for attack and defence, so that in all operations the infantry were directly supported by the maximum energy of his artillery covering them. The successes of the Division were in no small measure due to the effective manner in which the two arms co-operated. General Oldfield was continually moving towards artillery perfection. He set a very high standard to his officers, to which they admirably responded. In the later stages of the war, his energy as a commander had resulted in the Divisional artillery having reached a high degree of efficiency. They could improvise a barrage in a shortness of time which surprised many artillery commanders from other Divisions. They had, further, become extremely mobile, and were possessed of extraordinary initiative. Later chapters in this book will show how General Oldfield's officers not only handled their guns with great skill, but also, as a result of his teaching, were able in emergencies to take command of disorganised detachments of men and fight equally skilfully as infantry officers. During General Oldfield's command, all infantry commanders had complete confidence both in the artillery and in the artillery arrangements. General Burn was at the time of his appointment the youngest Brigadier in the British Army, being thirty-four years of age. Later in the war there were several younger, but prior to the Somme fighting the day of the young Brigadier had hardly come. He is perhaps best described by a Jock, who said, in speaking of him, "They a' have their fads, and his fad is effeeciency." General Burn had abundant experience of warfare in the front line. He had served as Adjutant, Staff-Captain, and Brigade-Major, and had commanded three separate battalions. It can safely be asserted that he spent every moment of the day, and much of the night, in thinking how he could increase the efficiency of his command and how he could do damage to the enemy. His vast experience enabled him to grasp details which actually were far-reaching in effect, but which to a man of less experience might have appeared trivial or have passed unnoticed. In every direction, even in the smallest points, he accepted only one standard--namely, the highest; nothing less was tolerated. He spared himself no pains to attain this standard. Holding these principles as strongly as he did, it is natural that he found it frequently necessary to check officers and N.C.O.'s. They, however, bore him no ill-will for this, and officers were frequently heard to say, "You can't argue with P.B. when he strafes, because he's always right." To those who served with General Burn he will always stand out as a man who possessed in full the essential qualities of the perfect soldier.
