The fighting had been mixed on September 29, but it became still more so next day, and it will tax the {157} industry of some Antipodean historian to trace each unit, Australian or American, and define their relations to each other. The rôle of the 15th Brigade was simple as it was directed to make good the rest of the Nauroy-Le Catelet line, which was in time accomplished. The 14th Brigade was ordered to attack northwards in order to help the left flank which had encountered such difficulties on the first day, while the 11th Brigade was also directed towards the north-east, and ordered to take a strong impediment called the Knob, which was eventually done. The 53rd Battalion which led the 14th Brigade distinguished itself greatly, advancing with a steady persistence which always gained its ends, and overflowing the German field-guns. It was finally held up, however, and a strong counter-attack drove it to take refuge in that part of the Le Catelet-Nauroy line which was already in British hands. There was a good deal of close fighting in this quarter but the gains were held by the 15th Brigade, which failed, however, to get Cabaret Wood Farm. On October 1 the 56th Australian Battalion, with the aid of tanks, carried Estrées. We shall now follow the work of General Braithwaite's Ninth Corps on the extreme right of the whole British Army on this great day of battle. This Corps consisted now of the First, Sixth, Thirty-second, and Forty-sixth Divisions. Of these, the Sixth Division (Harden) was in touch with the French, the First (Strickland) was in the centre, and the Forty-sixth (Boyd) was on the left. Opposite the Corps lay the broad and deep St. Quentin Canal, and the storm troops of the Forty-sixth Division were fitted up with 3000 life-belts, having proved {158} by experiment that they were buoyant enough to support a fully-equipped man. Since the Spanish infantry of Alva waded out neck-deep to attack the Dutch defences on the Frisian Islands there has surely never been a more desperate enterprise than this, when one remembers that on the farther side of the Canal was every devilment which German sappers could construct, while no tanks could lead the van of the stormers. The general plan was that the Forty-sixth North Midlanders should take the whole position between Bellenglise and Riqueval; that the Thirty-second Division (Lambert) should then pass through their ranks and push onwards to Tronquoy and beyond; while the First Division should carry out a difficult turning movement by swinging its left flank north-east to form a defensive line between Pontruet and the Canal at the right of the Forty-sixth Division's advance. The Sixth Division was to make threatening demonstrations.
