The 17th were ordered to send three Companies in support of the Border Regiment who were being hard pressed east of the Yser. "A," "B" and "C" Companies were despatched on this mission. These Companies experienced very stiff fighting throughout the night of the 10-11th, until relieved early in the morning of the 11th by the Northumberland Fusiliers.

On the following day the bombardment slackened a little, though during the night hurricane fire broke out, and over the period of this attack the Hun used a very large number of tear gas shells—which at that time was a new horror introduced to the sufferings of the British armies. Who will forget the Redans, Le Grand and Le Petit, the Bridges Putney and Pelican? The last named was renewed or rebuilt on the average three times every twenty-four hours. No words can describe what took place between the 10th and 13th of that awful month. The Germans, expecting an attack, made one. After these terrible three days, the Battalion, whose luck it was on this occasion to be spared the brunt of the action, after being relieved by the Borderers, struggled back through a mixed barrage of shells of all calibres, sprinkled with those of gas. There was a fog of gas and dust for miles behind the lines.

The enemy attempt had broken down; the Battalion returned to Ghyvelde of pleasant recollection, and on the 13th the Division was congratulated on its successful efforts.

On July 20th Major J. Inglis joined the Battalion and took over command at Bray Dunes Plage. On the 23rd the Brigade was inspected by the Divisional General, Major-General Shute. After his inspection he gave an address congratulating the Brigade on its part against the enemy attack on the 10th inst. at Nieuport, and on the same day the Corps Commander also inspected the Brigade, complimenting the men on their clean and smart appearance, and paying a high tribute to their fighting qualities.

August opened with the prospect of making an attack on the enemy and exercises were practised accordingly. On 6th August a Battalion reconnaissance was made which included reporting on all tracks to the front line, arranging an assembling position in "no man's land," and learning the condition of the existing wire in front of both our own and the enemy's line. The weather for some little time had been very wet, the night selected for the reconnaissance was very bright and none too suitable, and the condition of the ground was extremely muddy, making movement slow and difficult. After examining the whole situation it was recognised that any possibility of successfully attacking upon this position was out of the question. Indeed, the bad weather throughout August delayed whatever action had been contemplated by either side.

The 9th H.L.I. (The Glasgow Highlanders) were lying at Ghyvelde, and on 11th August, the 17th paid them a visit, while the Battalion football teams played a match. Another convivial day was spent on the 24th when the Battalion sports were held. The day cleared up to one of bright sunshine, and a large number of spectators enjoyed the sport. The events were continued on the following day when even a larger number of guests and spectators attended, including many Colonial soldiers, and the various events were keenly contested, both by the men of the home Battalion and those from others in the area. A good turn out of British and Belgian nurses from La Panne Hospital brightened the gathering, and at the conclusion of the sports the prizes were presented by two of the lady guests. On the Saturday following Brigade Sports were held under ideal conditions, the Battalion representatives winning numerous prizes.

At Church Parade on the 26th, the Presbyterian Service was conducted in camp by the Rev. Dr. Kelman, of Free St. George's, Edinburgh, who delivered a very impressive address which was listened to with the closest attention by the men. Dr. Kelman then left to preach to another Battalion and the 17th prepared to go back to the line.

The Battalion kept up its old record of keen patrolling, and during their front line spell at the beginning of September some reconnaissance work was well carried out under conditions unusually difficult. On the night of 3rd September, 1917, 2nd Lieut. Forbes and Corpl. J. Wilson of "C" Company waded across a swamped portion which lay between the Battalion positions and a point known as Roode Poorte Farm. Coming to a point where the water was too deep for wading, Corpl. Wilson swam across and on reaching ground crawled in the direction of the enemy lines. Finding this line of approach of no use for operations, he swam back to the point where the patrol was covering his movements, and selecting another point, swam across the canal which lay to the east, opposite the farm buildings, and carried out his reconnaissance.

On the 8th, while at Wulpen, a gas attack was successfully carried through on to the enemy's lines, and on the 13th, the third anniversary of the forming of the Battalion was spent in the trenches. A telegram congratulating the Battalion on its anniversary was received from the Brigadier, and a reply sent reciprocating the General's good wishes.

The enemy perpetrated a novel surprise raid, which had some of the elements of picture-house humour in it, on one of the Battalion advanced Listening Posts, and by their new device gained temporary footing in it. A strong stream of water, apparently from a hose was directed suddenly upon the men in the Listening Post from the enemy position. While the men were baffled and blinded by the rush of water, the post was bombed and the two listeners retired on the main post for support. Immediately a counter-attack was organised and led by Company Sergeant-Major Miller of "A" Company, and the post was re-established.
