This constant interchange of these Divisions, unavoidable as it probably was, undoubtedly militated against the attainment of the highest standard of efficiency. Uniform in scope and purpose as military administration and tactical policy aims to be when considered on broad lines, yet in a thousand and one matters of detail, many of them of dominating importance, the personality and the individual idiosyncrasies of the Corps Commander and of his principal executive Staff Officers, are calculated to exercise a powerful influence upon the functioning of the whole Corps.
Under each Corps Commander there grew up in course of time a particular code of rules, and policies, of technical methods and even of technical jargon—most of it in an unwritten form. This nevertheless tended towards efficiency so long as the whole of the component personnel of the Corps remained stable, but imposed many difficulties upon Divisions and other units which joined and remained under the Corps for a short period only.
The result was that a Divisional Commander and his Staff, accustomed to work in one environment, often found great difficulty, and occupied some appreciable period of time, in accommodating themselves to a new environment, in which doctrines of attack or defence, counter-attack or trench routine, supply or maintenance were, some or all of them, widely different from those to which they had formerly become accustomed.
But, in the case of Dominion troops, there was a motive far overshadowing the desire for a removal of difficulties of merely a technical nature. It was one founded upon a sense of Nationhood, which prompted the wish, vaguely formed early in the war, and steadily crystallizing in the minds both of the Australian people and of the troops themselves, that all the Australian Divisions should be brought together under a single leadership.
This ideal was associated with the hope that the Commanders and Staffs should to as large an extent as possible, consist solely of Australian Officers, as soon as ever men sufficiently qualified became available. It is difficult to emphasize such a desire without appearing to display ingratitude to a number of brilliant General and other officers of the Imperial Regular Service. These men, at a time when Australia was still able to produce only few officers with the necessary training and experience to justify their appointment to the command of Divisions and Brigades, or to the senior Administrative and General Staffs, bore these burdens in a manner which reflected upon them the greatest credit, and earned for them the gratitude of the Australian people.
I refer, among many others, particularly to General Sir W. Birdwood, Major-Generals Sir H. B. Walker, Sir N. M. Smyth, V.C. and Sir H. V. Cox and Brigadier-Generals W. B. Lesslie and P. G. M. Skene. But as the war went on, this aspect of the national aspiration became steadily realized; one by one, the senior commands and staff appointments were taken over by Australian Officers who had proved their aptitude and suitability for such responsibilities.
The other ideal of unity of command and close association with each other of all Australian units, proved slower of realization. All concerned thought and hoped that it had been, at last, achieved in December, 1917, when it was decided to abolish the two "Anzac" Corps, and to constitute a single Australian Army Corps. This was effected by the transfer of the Third Australian Division from Second to First Anzac Corps, by altering the title of "Second Anzac" to "XXII. Corps," and by substituting for the name "First Anzac" the name "Australian Army Corps," which name it bore until the termination of the war.
The only regrettable feature of this development was the dissolution of the close comradeship which had existed between the troops from the sister Dominions of Australia and New Zealand.
Even then all hopes were doomed to disappointment. For the next four months the Corps contained five Divisions in name only. Almost at once, the Fourth Australian Division was withdrawn to serve under the VII. Corps in connection with the operations before Cambrai. Not many weeks later, when the German avalanche was loosed, the whole five Divisions became widely scattered, and, for a time, the Third and Fourth Divisions served under the VII. British Corps, the Fifth Division under the III. Corps, and the First Division under the XV. Corps. It was not until April, 1918, that four out of the five Divisions again came together under the control of the Australian Corps Commander, at that time General Sir William Birdwood.
About the middle of May, 1918, this popular Commander was appointed to the leadership of the Fifth British Army. In deference to his long association with the Australian Imperial Force, he was asked to retain his status as G.O.C., A.I.F. His responsibilities as the Commander of an Army, and its removal to quite a different area in the theatre of war, made it, however, impossible for him to take any active part in the direction of the further operations of the Australian Corps.
