CHAPTER VI
THE OPERATIONS OF RAWLINSON'S FOURTH ARMY
From the Battle of the Hindenburg Line (September
29) to the Battle of the Selle, October 17
The first American operations—The rupture of the Hindenburg Line—Predicament of Twenty-Seventh American Division—Their gallant resistance—Great Australian attack—Remarkable feat by the Forty-Sixth North Midland Territorial Division—Exeunt the Third Corps and the Australians—Entrance of the Thirteenth Corps—Rupture of the Beaurevoir line—Advance to the Selle River.
Turning to Rawlinson's Fourth Army, which were last seen in contact with the old Hindenburg Line along its formidable front from Vandhuile on the left to Gricourt on the right, it will be remembered that it consisted of Butler's Third Corps on the left, the Australian Corps in the centre, and Braithwaite's Ninth Corps on the right in contact with the French. The time had now come for an attack on the largest scale in order to endeavour to carry this Chinese Wall of Germany by storm. The part assigned to the Third Corps in this important operation was not a large one, and their front was now contracted to 2000 yards, while two of their divisions, the Fifty-eighth Londoners and the Seventy-fourth Yeomanry, were transferred to another area. There remained only the Twelfth and Eighteenth Divisions in line, which had to cover the left flank of the main attack which was to be made by the Australian and Second American Corps, and by Braithwaite's Ninth Corps to the south of them.
Sept. 27.
At this point the great Canal de l'Escaut passes under a tunnel which is nearly six miles in length. Thus it is the only place in the whole line where tanks could be used to advantage. The general plan was that this section of the line should be carried by the Second American Corps as far north as the northern entrance of the tunnel. This done they would extend their gains to the left in a north-easterly direction beyond Vandhuile, so as to open up a way for the Fifth Corps. After the line had been taken Australian Divisions were to move forward through the Americans and push the advantage to the east. The rôle of the Third Corps was to cover the left of the Americans, and then, when the latter had moved northwards, to mop up Vandhuile, establish bridge-heads east of that point, and bridge the canal for the Thirty-eighth Welsh Division on the right of the Fifth Corps to get across.
Before the general attack which took place on that dies irae, September 29, the Americans had a brisk fight of their own, which deserves some special mention as it was the first large operation of an American force acting as part of a British Army. The Second American Army Corps (General Read) had been specially selected to lead the attack on September 29, and as a preparation for this great effort they were ordered to make some advance along their whole front in order to gain an advantageous point from which to start. They lay roughly along the front of the Hindenburg outpost line, but they needed to draw up closer to the main line before the day of battle. On the night of September 24, General O'Ryan's Twenty-seventh American Division from New York on the left relieved the Eighteenth and Seventy-fourth British Divisions, taking over a front of 4500 yards opposite to Gouy. The defences immediately before them were particularly strong, including the notorious danger points, the Knoll, Quinnemont Farm, and Guillemont Farm. The 53rd American Brigade (Pierce) took over the line, with the 106th Infantry Regiment in front and the 105th in support. The entire American front was from near Vandhuile in the north to Bellicourt in the south.
The tunnel, which formed a special feature in the next great battle, deserves some description, as it was a remarkable feature dating back to the First Empire, and still bearing upon its arches the laconic N of the great Corsican. It is 6000 yards long and averages 50 feet below the surface, with a breadth of about 70 feet. The Germans had converted it into an extraordinary military work, for it was stuffed with barges in which a whole division could take absolute refuge from the heaviest barrage ever launched. There were all sorts of bolt-holes in every direction for getting in or out, and there were powerful machine-gun emplacements along the top. Altogether it was as awkward a nut to crack as any military engineer could conceive. The main Hindenburg Line lay a couple of hundred yards west of the tunnel, a heavily-wired system of trenches. About a mile farther east was a strong support line joining the villages of Nauroy and Le Catelet, while two or three miles farther on was yet another strong position, known as the Beaurevoir line. The way in which Americans, Australians, and British combined with equal valour to hunt the Germans out of this terrific series of positions is a story which will go down in the common traditions of the English-speaking race.
At 5.30 A.M. on September 27 there was the preliminary operation, already mentioned, which should gain the ground necessary for the jumping-off place. This was done by General Lewis' Thirtieth American Division on the right with little difficulty. It was different with the Twenty-seventh on the left. On this flank a depth of about 1100 yards had to be gained, coinciding roughly with the rearmost trenches of the Hindenburg outpost line. This task was carried out by the 106th Infantry with all three battalions in line and four tanks ahead of each battalion. The leading companies, following the barrage, reached their objectives in most cases, but were involved in desperate fighting at the points already mentioned, which were connected by cross-cuts with the main German line, from which there flowed an endless supply of reinforcements. All day attack and counter-attack followed each other, both parties fighting with great valour and enduring heavy loss. By night the 53rd American Brigade was well advanced on its right, but its left was still battling hard to reach the allotted line: 8 officers and 259 Germans had been taken in the fighting. That night the 54th Brigade (Blanding) took over the new front and lay ready for the coming battle, with the 108th Infantry on the right and the 107th on the left. On the front of the Thirtieth Division the 60th Brigade (Faison) was in line, with the 119th and 120th Infantry in the van, the latter to the right, in touch with the British Ninth Corps to the south of them.
