The Battalion War Diary of the 1st/6th King's records:

"30/11/17 12 am Enemy very quiet. Shelling normal.

7 am Enemy opened a very heavy barrage on our front line and Support, which was followed by infantry attack. The BIRDCAGE and OSSUS WOOD sector fell into the enemies' hands, there being very few men left alive in the front line, from reports received, to offer much resistance after the barrage lifted. The Supports in HEYTHROD and CRUCIFORM POSTS offered stubborn resistrance, however, and succeeded in repelling the enemy, who then occupied LITTLE PRIEL FARM, but was eventually driven out of this position. The enemy coming down the CATELET VALLEY in large numbers succeeded in taking HOLTS BANK which was the Support POSTS on our extreme left flank. The RESERVE Coy in the meantime had reported at Bn H.Q. and the reserves supporting points were strenghtened - 1 platoon being sent to HOLTS BANK, but were unable to reach same as it was very strongly held. Our left flank was very much in the air and various flank defences were made, the 9 K.L.R. reinforcing us in the evening, We were then able to hold on. The shelling throughout the day was very heavy, and we were quickly enfiladed by M.G. fire. Approximate casualties, 9 officers

Capt G.D. Tyson, Lt R.R. Stewart, 2/Lt W.K. Davy, 2/Lt W.R. Smith, 2/Lt C.V. Watts, 2/Lt H.J. Cheppard, 2/Lt S.H. Webster, 2/Lt E.S. Rogers and 2/Lt V.R. Bowers all missing.

The History of the King's Regiment (Liverpool) 1914-1919 Volume III records:

"The night of the 29th/30th was exceptionally quiet, and although the troops had been warned that the enemy might attack, "stand to" on the 30th passed without any signs of the enemy. But at 7.5 a.m. the enemy's guns suddenly broke the stillness of the morning and soon a very heavy gas barrage was in progress near the left battalion of the 165th Brigade (1/6th King's), all roads and tracks in the neighbourhood being subjected to a very violent bombardment. Simultaneously with the barrage the enemy, in great numbers, attacked Fleeceall Post, Eagle Quarry and The Birdcage (roughly the centre of the divisional front) and the front-line trenches of the 166th Brigade ...

The 1/6th King's suffered very heavily from the enemy's barrage. They state that The Bidcage and the Ossus Wood Sector fell inteo the enemy's hands, "there being very few men left alive in the front line, from reports received, to offer much resistance after the barrage lifted." The supports, however, in Heythrop and Cruciform Posts were not so badly affected as to be incapable of resistance, for they put up a very stubborn fight and flung back the enemy, though they could not prevent him occupying Little Priel Farm; from that place he was eventually driven out. Great numbers of the enemy, pushing down the Catelet Valley, seized Holts' Bank and support posts on the extreme left flank of the 1/6th King's.

The reserve company had re-formed in the meantime at Battalion Headquarters, which were situated on the Lempire Road in rear of Heythrop Post. One platoon of this company was then sent to Holts' Bank, but they could not re-occupy it as the enemy was in too great a strength; the other platoon was sent up to strengthen various supporting posts. The left flank of the Battalion was very much in the air and various flank defences had to be improvised. During the evening the 1/9th King's reinforced the 1/6th and the latter were able to "hold on"."
