no other change on the front until the great battle which shattered the Hindenburg Line and really decided the war. All of this fighting, and especially that on September 18, has to be read in conjunction with that already narrated in the story of the Fourth Army on the right. Having brought Shute's Fifth Corps up to the eve of the big engagement we shall now ask the reader to cast his mind back to August 21, the first day of General Byng's advance, and to follow Haldane's Sixth Corps on the northern flank of the Army during these same momentous and strenuous weeks. It will then be more easy to trace the operations of Harper's Fourth Corps, which was intermediate between Shute and Haldane. [Sidenote: August 21.] Haldane's Sixth Corps, like its comrades of the Third Army, had gone through the arduous days of March and had many a score to pay back to the Germans. It was a purely British Corps, consisting upon the first day of battle of five fine divisions, the Second (Pereira), Third (Deverell), Sixty-second (Braithwaite), Fifty-ninth (Whigham), and the Guards. With four Regular units out of five, Haldane's Sixth Corps might have been the wraith of the grand old Mons army come back to judgment. The First Cavalry Division, also reminiscent of Mons, {99} was in close support, ready to take advantage of any opening. The first advance in the early morning was made by the 99th Brigade of the Second Division on the south, and the 2nd Guards Brigade on the north, the latter being directed upon the village of Moyenneville, while the 99th Brigade was to carry Moyblain Trench, the main German outpost position, 1000 yards in front of the line. The right of the line was formed by the 1st Berks and the left by the 23rd Royal Fusiliers, the latter having a most unpleasant start, as they were gas-shelled in their assembly places and had to wear their masks for several hours before zero time. Any one who has worn one of these contrivances for five consecutive minutes will have some idea what is meant by such an ordeal, and how far it prepares a man for going into battle. Only a very expert man can keep the goggles clean, and one is simultaneously gagged, blinded, and half smothered, with a horrible death awaiting any attempt at amelioration.
