The War Diary entry for the 19th August 1916 records. “A” Company were pushed out as an outpost Company and at 2.00pm sent forward patrols and established a line of posts on the ridge. Two Companies of the ROYAL SUSSEX REGT and one of the WELSH REGT were sent to consolidate this line. In the dark about 50 Germans got round on the right from the direction of HIGH WOOD amongst this party and caused considerable confusion as a result of which Captain J. C. CLAYTON was killed and 2nd Lt. LINGHAM wounded.
The War Diary entry for the 20th August 1916 records. About 7.00am the enemy advanced in force against the outpost Company which withdrew from its position on the ridge. The position was counter attacked immediately by “B” and “A” Companies and the fight lasted all morning. During this time 2nd Lt. GREENWOOD was killed and 2nd Lt. TAPPIN and 2nd Lt. ROGER TYLER were wounded. After a rather ineffectual artillery preparation “B” and “A” Companies and 2 Companies of the ROYAL SUSSEX REGT went over again at 2.30pm and after a very severe fight established a post about 300 yards in front of the newly taken trench from which an excellent view could be obtained for artillery observation. This post was consolidated and handed over to the 2nd WELSH REGT on relief. The relief was in progress throughout the night and the Battalion arrived in BACOURT WOOD at about 4.00am on the 21st August. The thanks and congratulations of all the higher command were duly passed on to the Battalion for a particularly brilliant and glorious period in the
attack. All its objectives were gained and in spite of very heavy losses the spirit and tenacity of the Regiment were maintained throughout. Casualties, killed 19, wounded 91 and missing 28. Total 138.
