In January 1916 the Lancashire Brigade left to join their own Division and the 51st received the 9th Royal Scots, 4th Seaforths, 4th Gordon Highlanders and 7th Argyll and Sutherland Highlanders.
Sir Douglas Haig’s despatch of 23rd December, 1916, which deals with the Somme Battle, paragraph 17 (Dent’s edition), mentioned various engagements, now called the “Battle of Bazentin Ridge,” in the latter half of July. “That evening (24th July) after heavy artillery preparation, the enemy launched two more powerful counter-attacks, the one directed against our new position in and around High Wood (51st Division, Major-General G. M. Harper) and the other delivered from the north-west of Delville Wood. Both attacks were completely broken up with very heavy losses to the enemy.” The Division had attacked on the 22nd-23rd but had failed to gain much ground.
Paragraph 19 and note: Early in August the 51st, along with other divisions, was in other operations “involving much fierce and obstinate fighting,” by which the line was pushed forward. About the 7th of August the Division was relieved and taken to Armentières. In the beginning of October the Division again went south, at first to Hebuterne and on the 17th to Beaumont Hamel.
Paragraph 33 and note, also 35 and 36 of the despatch, show that the 51st along with other troops took part in the attack on the Beaumont Hamel-St. Pierre Divion position on 13th November, now the “Battle of the Ancre, 1916.” In a note to paragraph 33 it is remarked: “As the season advanced and the bad weather continued the scope of our plan had constantly to be reduced, until finally it was only possible to undertake the much more limited operation of the 13th November against Beaumont Hamel. The brilliant success of this attack, carried out as it was under most difficult conditions of ground, affords some indication of what might have been accomplished had the weather permitted us to give fuller effect to our original plan.” The 51st Division captured the village, which was very strongly fortified, and over 2000 prisoners, their own losses being about 2500.
The “brilliant success” of the Division in the Beaumont Hamel battle brought it fame which was to endure and increase as the years of the war rolled on.
During December 1916, and part of January 1917, the Division was in the Courcelette sector where things were far from peaceful and hardships were extreme. In February they moved north to Arras, and remained there till the Battle of Arras.
The despatch of 25th December, 1917, paragraphs 13 and 14, and note to paragraph 13 (Dent’s edition), describes the opening stages of the Battles of Arras which began on 9th April, 1917. The 51st, then in the XVII. Corps, Third Army, attacked east of Roclincourt, north-east of Arras; they were near the left of the line and next the Canadians whose task it was to seize the main Vimy Ridge. The 51st and its neighbour on the right, the 34th, had heavy fighting. “Their advance was delayed, not checked.” The whole attack on the 9th was a great success. The fighting between the 9th and 14th is now the First Battle of the Scarpe, 1917. On the 12th the Division left the line, re-entering it on the 15th-16th and remaining in the battle till the 24th-25th.
Paragraph 21 deals with a big attack which our troops made on 23rd April on a front of nine miles, the Second Battle of the Scarpe, 1917. “North of the Scarpe Highland Territorials (51st Division) were engaged in heavy fighting on the western outskirts of Rœux Wood and the chemical works.” “During the afternoon many counter-attacks developed all along the line and were repeated by the enemy with the utmost determination regardless of the heavy losses inflicted by our fire.” “North of the Scarpe fierce fighting continued for the possession of Rœux, the chemical works and the station to the north without producing any lasting change in the situation.” The attack was renewed on the 24th and more progress was then made, the enemy’s resistance weakening. For their “splendid” work on the 23rd, the Division was thanked and congratulated by the Corps and Army Commanders.
The losses of the Division during April amounted to about 4500.
Paragraph 27, as to the fighting in May, Third Battle of the Scarpe, 1917: “On the night of the 13th-14th our troops (51st Division) captured Rœux.” The Division drove back some very heavy counter-attacks. Fighting continued for some days. The Army Commander again wired to the Division his congratulations “on their great gallantry at Rœux and the chemical works.”
