Nevertheless, he put up a good fight, and employed well-considered tactics. The German Machine Gun Corps was much the best of all his services. The manner in which the machine gunners stood their ground, serving their guns to the very last, and defying even the Juggernaut menace of the Tanks, won the unstinted admiration of our men. During these three days of retreat the enemy used his machine guns to the best advantage, and they constituted the only obstacle to our rapid advance.

These tactics were not unexpected by me, and I had an answer ready. Defying the whole traditions of Artillery tactics in open warfare, I insisted upon two somewhat startling innovations. The first was to break up battery control, by detaching even sections (two guns), to come under the direct orders of Infantry Commanders for the purpose of engaging with direct fire any machine-gun nest which was holding them up.

The second was to insist that all batteries should carry 20 per cent. of smoke shell. This elicited a storm of protest from the gunners. Every shell carried which was not a high explosive or shrapnel shell meant a shell less of destructive power, and, therefore, a shell wasted. That had been the Gunnery School doctrine. But I imagine that the test made at this epoch of the liberal use of smoke shell against machine guns will lead to a revision of that doctrine.

Smoke shell proved of inestimable value in blinding the German machine gunners. A few rounds judiciously placed screened the approach of our Infantry, and many a machine-gun post was thereby rushed by us from the flanks or even from the rear. General Hobbs (Fifth Division) and General Rosenthal (Second Division), both of whom had formerly been gunners, proved the strongest advocates for these smoke tactics.

By such means an energetic and successful pursuit was launched and maintained. By the night of August 27th, our line already lay to the east of the villages of Vermandovillers, Foucaucourt (on the main road) and Fontaine. We also mastered the whole of the Cappy bend, including the crossings of the Somme at Eclusier. The Fifth Division had a particularly hard fight at Foucaucourt, which did not fall to us until we had subjected it to a considerable bombardment. Tivoli Wood was the chief obstacle encountered that day by the Second Division. The advance of the 32nd Division also progressed smoothly.

During August 28th our advance was continued methodically, and by that night the Corps front had reached the line Génermont—Berry-en-Santerre—Estrées—Frise.

On August 29th the line of the Somme was reached, and all three Divisions south of the Somme stood upon the high ground sloping down to the Somme, with the river in sight from opposite Cléry, past Péronne and as far south as St. Christ.

In the meantime the Third Division north of the Somme had marched forward, in sympathetic step with the southern advance, successively seizing Suzanne, Vaux, Curlu, Hem and Cléry. The Third Corps on my left had followed up the general advance, though always lagging a little in rear, thus keeping my left flank secure; and beyond the Third Corps, the Third Army was approaching the line of the Canal du Nord, which lay, as explained, in prolongation of the south-north course of the Somme.

The war correspondents of this time were given to representing the progress of the Australian Corps during these three days as a leisurely advance, regulated in its pace by the speed of the retiring enemy. But it was nothing of the kind.
