On the night of 8^th/9^th the Battalion moved up to its assembly trenches in preparation for the attack on the Harp on the following morning. Operational orders and Report on the Action are attached hereto. The weather at this time was exceptionally cold with some snow on the ground. While holding the line in the Harp after the attack by dint of hard labour and a complete lack of knowledge of engineering a medium Minenwerfer was dismantled and removed from its emplacement, fitted together again and placed on wheels with the aid of a few pat mills and HQ orderlies this was drawn triumphantly to Brigade HQ where it was duly handed over. During the afternoon on the 12th the battalion was relieved by 9th rifle brigade and went back to the old German line where it remained.

The 9^th Battalion King's Royal Rifle Corps was part of 42^nd Infantry Brigade, 14th (Light) Division. The divisional objectives for 9 April were to capture the strong German position known as the Siegfried Stellung, (Hindenburg Line) which the Germans had fallen back to throughout the month of March.  The hinge of the ‘old’ German line and new Hindenburg Line was the village of Tilloy-lès-Mofflaines. South of the village lay the 14^th Division’s objective, the southern part of The Harp, a formidable position some 1000 yards long and 500 yards wide, full of tangled field defences.  Along with Telegraph Hill to its immediate south its dominant position enabled German defenders to fire in enfilade northwards up Observation Ridge and southwards to Neuville Vitasse; its capture was absolutely critical.

An initial assault was to be made against the southern portion of ‘The String’, a trench running down the length of The Harp, by the 5^th Ox and Bucks Light Infantry and 9^th King’s Royal Rifle Corps. Once captured the 5^th King’s Shropshire Light Infantry would then pass through or ‘leapfrog’ the two battalions to capture the second objective close to the Blue Line running south from the rearward face of The Harp down the Hindenburg Line. Nearly seven hours after the initial advance and with these objectives taken B & D Companies of the 9^th Rifle Brigade, under the command of Captain Buckley were to leave their positions in and around the old German front line to clear the ground between the Blue and Green lines within the Brigade boundaries.
