It was there, soon after my arrival, that I learned of the presence in the neighbourhood of Major-General Maclagan; this news, implying as it did the presence also of some at least of the Fourth Australian Division, was a gleam of sunshine in an otherwise gloomy prospect. Report said that he was at Basseux, and thither I proceeded, in order to arrange, by personal conference with him, some plan for co-ordinated action.
Basseux rests on the main road from Doullens to Arras, which lies roughly parallel to the line along which, as subsequently transpired, the vanguard of the enemy was endeavouring to advance at that part of the front. That main road I found packed, for the whole of the length which I had to traverse, with a steadily retreating collection of heterogeneous units, service vehicles and guns of all imaginable types and sizes, intermingled with hundreds of civilian refugees, and farm waggons, carts, trollies and barrows packed high with pathetic loads of household effects. The retrograde movement was orderly and methodical enough, and there was nothing in the nature of a rout, but it was nevertheless a determined movement to the rear which evidenced nothing but a desire to keep moving.
I found Maclagan at about four o'clock. His Division had already been on the move, by bus and route march, for three days without rest. The position to the east and south-east of him was obscure, and he also had posted a line of outposts in the supposed direction of the enemy, and was arranging to despatch his 4th Brigade to Hebuterne (which the enemy was reported to have entered), with orders to recapture that town. That the enemy was not very far away became evident from the fact that the vicinity of the hut in which we were conferring presently came under desultory long-range shell-fire.
There was nothing to be done except to arrange jointly to keep up an effective and as far as possible continuous line of outposts towards the south-east, and to await developments. Having made these arrangements I returned along the same crowded road, which was now also being leisurely shelled by the enemy, to Couturelle. There I found that the principal officers of my Staff had arrived.
Thereupon orders were issued for the concentration, after detrainment, of my three Brigades in the following areas, each with due outpost precautions, viz.: 9th Brigade at Pas, 10th Brigade at Authie, and 11th Brigade at Couin. My Artillery was still distant a full day's march by road.
About nine o'clock that evening I received, by telephone, my first order from the Tenth Corps. It ran as follows: "A Staff Officer has left some time ago on his way to you, carrying instructions for you to report personally at once to Corbie for orders. We have since heard that you are to go to Montigny instead."
It was nearly an hour before the Staff Officer arrived, having been delayed on the road by congestion of traffic. The instructions he carried transferred my Division from the Tenth to the Seventh Corps, to whom I was to report personally, without delay, at Corbie. It was evident from the later telephone message that the Seventh Corps had been compelled to withdraw from Corbie, and was proceeding to Montigny.
This was the second stroke of good luck that day; for if the telephone message above recited had not overtaken the Staff Officer, it is quite probable that I should have already started for a wrong destination, and have had to waste valuable time at a most critical juncture. Had I failed to find General Congreve, the Seventh Corps Commander, that same night, it is almost certain that my Division would have arrived on the Somme too late to prevent the capture of Amiens.
Setting out from Couturelle shortly after ten o'clock that night, accompanied by four of my Staff and two despatch-riders, with two motor-cars and two motor cycles, in black darkness, on unfamiliar roads congested with refugee traffic, I did not reach Montigny until after midnight. I found General Congreve in the corner of a bare salon of stately proportions, in a deserted château by the roadside, seated with his Chief of Staff at a small table, and examining a map by the flickering light of a candle. The rest of the château was in darkness, but heaps of hastily dumped Staff baggage impeded all the corridors.
