Major Paul then took over command of the 17th and that evening once more they moved into the trenches in support at Quarry Post, Authuille Wood.

On the 13th July a bombing party of about 100 men were ordered to attack the German Line, north of Ovillers, linking up with the Inniskillen Fusiliers, and this party at midnight under Captain Ferguson, Lieuts. Herron and Kirk and Sergeant Stewart, in conjunction with the Inniskillens and a party of Engineers, carried out the raid.

The greatest credit was due to the initiative shown by Captain Ferguson, in making excellent dispositions under very difficult conditions. Owing to the strength of the German wire, a frontal attack was impracticable, and after much thought, it was decided to attack obliquely. The attack was most successful, a considerable number of Germans being killed, while at least 16 were taken prisoners. The objectives were all taken in a few minutes, but unfortunately the raiders' losses were heavy. Captain Ferguson was mortally wounded, eight other ranks were killed, and the other two officers and about 35 other ranks were wounded.

Writing of this incident, one of the Battalion officers says that after the patrol had gone out those who were not taking part in it heard the firing and the clamour of the small battle while they waited eagerly for news of its progress. "News came in that the front was safe, and proud of the efforts of our Battalion, we waited for their return. The waiting was hard to bear, but the return sadder to witness. They came back. On the right they had succeeded. On the left they had died. A triumph and a disaster in one. On that small field were left yet more of the (oh! so sadly few) gallant men of the Seventeenth who, though exhausted and battle-worn, had in their own true and fine spirit responded to the uttermost to the call for gallant work. Later the body of Captain Ferguson was found right up to the German lines grasping an empty revolver, far ahead in the charge of even his gallant followers."

For this action, the Battalion received thanks and congratulations from the Corps and Division. A counter-attack drove the raiders out of the captured trench; but the object of the raid—to create a diversion from a major operation on the right—had been successfully accomplished.

This particular week, which was the last the Battalion saw of the Somme fighting until later in the year, was one of the most strenuous times which the unit had experienced. The available men for defensive purposes were only too few and as new assembly trenches had to be dug every night and all night, and also owing to the difficulties of rationing and watering, the men were unable to get any rest.

The Brigade commenced a move to Ampliers on 16th July, and on the road the Battalion was met by Lieut.-General T.L.N. Moreland, commanding the X Corps. He expressed to the Commanding Officer his appreciation of the good work done by the Battalion while under his command, and his deepest sympathy in their losses. On the 26th the Brigade moved into Bethune and two days afterwards paraded in full marching order, including "tin hats," on a sweltering afternoon, to be inspected by General Munro, G.O.C., 1st Army. A very warm day. Owing to the calls on an Army Commander's time, this inspection was considered to be a great honour and a mark of appreciation by the authorities of the fine spirit shown by the Division during the Somme battle.

August saw the unit leave Bethune to take over the Cambrin right sub-sector from the Northamptons, after putting in some fine shooting on the old French Government Rifle Range at Labeauvriere. The strength of the unit in the trenches apart from the officers, at the taking over (August 5th) was 199—tragic testimony to the Somme. Immediately on taking over the trenches they were subjected to trench mortar bombardments and sniping raids. On 12th August Lieut. and Adjutant Paterson became Captain and Adjutant, Major Paul became Lieut.-Colonel, and 2nd Lieuts. Morrison and Marr, Captains.

The following weeks of August, September and October were marked with much moving about with various spells of that sort of uneventful trench warfare which is perhaps in some respects more trying on the nerves and strength of a unit than actual operations. On August 23rd they were in the Hulluch Section. In this Section there was a good deal of mining going on and there were two big craters which required special watching, but the Battalion soon set to and trained in grappling hook work to be ready for any kind of crater fighting that might be demanded of them. On August 31st a move was made to Annequin via Beuvry and Bethune, and ultimately by bus journey to the trenches at Guinchy left sub-section, and in this area the unit remained during September. On the 11th of the month a night raid was attempted, but was frustrated owing to the Germans bombing the party as it was on the point of entering their trenches. Unfortunately the two N.C.O.s who fired the torpedo were missing, and it is presumed that they were blown to bits by the explosion.
