The book Advance to Victory 1918 : Somme [Michael Stedman 2001 Pen & Sword Books, Barnsley] states that:

“To the north of 36 Brigade the attack was carried out by 55 Brigade’s 7th Queen’s. Their task was to seize the ground on the north of the Bray – Corbie road. This battalion faced a resilient counter attack by German soldiers belonging to the 120th and 123rd regiments of the 27th Division. Not waiting to be attacked through the mist in their own trenches the Germans had swept forward behind a shower of stick grenades, causing the 7th Queen’s to lose their barrage and become engaged in close quarter fighting in the area of Cloncurry Trench, a part of the line which the 18th Division had lost on 6th August. Within a short time isolated parties of the Queen’s were being overrun and it was left to their commanding officer, Lieutenant Colonel Christopher Bushell, V.C., D.S.O., to bring forwards the remaining details at 7.00am and drive the Germans back from the old British front line. Whilst directing the tanks, which were now making their way forward, and exhorting his men Bushell was shot through the neck and mortally wounded……Cloncurry trench, an old British support position, lay almost directly opposite the site of Beacon Cemetery. The actual British front lines which had existed in this area and been lost in the German attacks of 6 August were located a little way to the east of Beacon Cemetery and lay some 300 meters west of the D42 Sailly Laurette – Morlancourt road as it crosses the Morlancourt ridge. That slightly higher ground between Beacon Cemetery and the road… is immediately clear why this position was a vital one to recapture, prior to any subsequent advances eastwards along the Morlancourt ridge, since the location provided dominant observation in this area. The attack of the 18th Division therefore ended on their first objectives, although their advance could have seen the capture of Gressaire Wood with more good fortune and a better performance from the tanks. Many of the tanks had lost direction in the morning mist….Of one company four tanks broke down before arrival at their starting point. Of the second company, four were held in reserve, one lost direction and joined the 12th Division, and two broke down. The others are said to have engaged any machine gun posts which could be located. The reserve section went as far as the second objective. Seventeen of the 36 tanks rallied in the evening”
On 1 August 1918, a week before the commencement of the Battle of Amiens, the official effective strength of the 7^th Battalion was 38 officers and 938 other ranks and the War Diary notes, for 7 – 10 August, four officers were killed (and another six were wounded) with 24 other men killed and a further 241 missing, wounded or injured
