The early hours of March the 22nd, which dawned in thick mist like the day before, passed fairly quietly. For the moment, the right flank of the Division and the III. Corps on its right being behind the barrier of the Canal de St. Quentin, the greater pressure was shifted to the north. In bitter fighting the troops of the 1st Inniskillings held their ground in the forward positions of the Battle Zone, till 2 p.m., when, completely outflanked, they were ordered to withdraw to Ricardo Redoubt, the headquarters redoubt in the Battle Zone, upon which attack after attack was launched, to be beaten off with heavy losses by the defenders. The Germans across the Canal were meanwhile far in their rear, having batteries in Artemps by now. Finally, Ricardo Redoubt was surrounded, the 9th Inniskillings being compelled to fight a rearguard action back to the Happencourt-Fluquières Line, upon which, as has been recorded, were troops of the 60th Brigade. On the right the Canal Line held, though the enemy had brought up batteries, trench mortars, and machine-guns under cover of the mist, and was bombarding it heavily. At noon General Nugent was informed that, in consequence of the decision of the Higher Command to hold the line of the Canal de la Somme and its continuation southward, the Canal de St. Quentin, a further withdrawal was necessary. The 36th Division, with the 61st Brigade attached, was now to hold this position from the present right flank of that Brigade to Sommette-Eaucourt. The 61st Brigade had already a battalion, the 7th D.C.L.I., holding from the Canal junction to a point west of the Dury-Ollézy Road, less one company, which had been moved down to the right flank to fill a gap between its right battalion, the 7th Somerset L.I., and the troops of the 14th Division. Its other battalion, the 12th King's, was driven out of Tugny at dusk by the advance of the enemy north of the Canal de St. Quentin, crossed the Canal de la Somme at Dury, and was withdrawn through the 7th D.C.L.I. to support on the railway behind that battalion. The withdrawal of the Brigades of the 36th Division was complete at 11 p.m., when the last troops passed through Pithon. The 108th Brigade took over the defence of the Canal bank from the left of the 7th D.C.L.I. to Sommette-Eaucourt. The 107th Brigade moved to Eaucourt and Cugny, the 109th to Brouchy in support. As no touch could be obtained with the 30th Division, which was to have prolonged the line westward, by the 108th Brigade, the 21st Entrenching Battalion, which had now come under General Nugent's orders, was put in on the left of the Brigade.
