The Twentieth Light Division was on the left of the Twelfth, and its experience was equally trying. It was upon the Riflemen of the 59th Brigade that the main shock fell, and it came with such sudden violence that the Germans were through the right unit and in {277} the rear of the rest before the situation was fully realised. The 61st Brigade upon the left had also a most desperate time, their flank being penetrated and turned so that for a time they were cut off from their comrades of the Twenty-ninth Division at Mesnières. By this determined German attack the south bank of the canal was partially cleared for their advance, which put them in the position that they could possibly push along that bank and get hold of Les Rues Vertes and the southern ends of the bridges so as to cut off those British troops who were across the canal. In this dangerous movement they nearly had success, and it was only the desperate fighting of some of the 86th Brigade which saved the situation. The prospects were even worse upon the right of the Division for the Germans broke through Lateau Wood, and so got completely behind the 10th K.R.R., who were the flank battalion. From the desperate struggle which ensued only 4 officers and 16 Riflemen ever emerged, for the battalion was attacked on three sides and was overwhelmed after a long and splendid defence, which twice repulsed heavy frontal attacks before the flank advance rolled up the line. The battalion got separated from its own headquarters in Lateau Wood, and Colonel Sheepshanks with the twenty odd men who composed the Staff fought a little battle of its own against the stormers coming down towards the Bonavis-Mesnières Road. The survivors of the brigade rallied upon the reserve battalion, the 11th R.B. on the Hindenburg Line. The 11th K.R.R. on the left of the brigade front had endured a similar experience but their losses were not so terribly severe. The aeroplane attack worried the troops almost as much as the infantry, so that it is no {278} exaggeration to say that there were times when they were assailed from four sides, the front, each flank and above at the same instant. These aeroplanes gave the impression of being armour-clad and invulnerable to rifle-fire.
