General Turner's Third Brigade, which, as previously noted, was holding the Canadian left on April 22, 1915, and after attacking had taken over the defense of the new Canadian salient, had also sent a detachment to establish a line between the wood and St.-Julien. Here they were subjected to a heavy gas attack followed by two enemy assaults. They were unprovided with the means for protecting themselves against the gas, but a wet handkerchief stuffed in the mouth was found to afford relief, and they held their ground beating off the heavy attacks in which the enemy lost heavily. The assault on the wood, as previously narrated, followed.

About 4 a. m. on the following day the Germans made a gas attack on the Second Brigade holding the line which ran northeast, and the Third Brigade which continued the line up to the pivotal point and then extended down in a southeasterly direction. The Royal Highlanders of Montreal, 13th Battalion, and the 48th Highlanders, 15th Battalion, were especially affected by the gas. The trenches of the 48th Highlanders became so untenable for a time that they were forced to retire until conditions improved.

During the night of April 23, 1915, the Third Brigade, which had displayed fearless courage and tenacity, was subjected to an unusual strain when the Germans attempted to sweep around and smash their left wing. One attempt succeeded in part, considerable numbers pushing past the unsupported left of the brigade, taking up a position between the wood and St.-Julien. This added to the difficulties of the Canadians, who felt that they were isolated from the brigade base.

The situation called for heroic action, and it would be impossible to select any battalion for special commendation in this hour of crisis when all displayed such valor and fortitude. The fate of some of the officers must be briefly described.

Major Norsworthy, who was in the reserve trenches half a mile back of the firing line, was killed while attempting to bring up reenforcements to Major McCuaig. Captain Guy Drummond fell while he was engaged in rallying French troops. The death of these officers left Major McCuaig to handle the situation. Through the afternoon and night, his communications cut and without artillery support, this intrepid fighter held on. The Germans were strong enough to overwhelm him, knowing the weakness of his position; that they held off was because they feared his supports when in reality he had none. When daylight came, revealing the weakness of the defense to the Germans, the wounded having been evacuated. Major McCuaig withdrew his men under fire as Major Buchanan with reenforcements appeared on the scene.

The battalion, which had faced such fearful odds and held on until relieved, occupied dugouts until dark when they retired to a new line. Having waited until all the wounded were removed, Major McCuaig, who had faced death every moment during that terrible struggle, was wounded and captured by the enemy.

The officers of the 7th Battalion (British Columbia Regiment) displayed no less valor during the fateful struggle than those whose fate has been described. This battalion, which was attached to the Third Brigade, occupied on April 23, 1915, the forward crest of a ridge, with its left flank near St.-Julien, and throughout the day was under a blasting shell fire. After receiving orders in the afternoon to strengthen the position for holding it during the night, Colonel Hart-McHarg of Vancouver, Major Odlum (afterward Lieutenant Colonel commanding the battalion), and Lieutenant Mathewson of the Canadian Engineers went out to choose the site for the new trenches which were to be due as soon as darkness fell. Not knowing exactly where the German lines were located, they suddenly became aware of the enemy lining the hedges not more than 100 yards away. In the hurried retreat Colonel Hart-McHarg was seriously wounded. Lieutenant Mathewson remained with him while Major Odlum ran in search of help. After dark Colonel Hart-McHarg was carried back to battalion headquarters, but died during the night.

Major Odlum succeeded to the command of the battalion, which continued to fight off enemy attacks until, flanked both right and left, it was forced to retire, its fighting strength being reduced to 100 men.

The 7th Battalion, after being strengthened by additional troops from the 10th, was again sent into the fight on the following day, to hold a gap in a Canadian line. Here it stood fast and fought until surrounded by the enemy, when the battalion succeeded in withdrawing under cover of a heavy mist. In the course of three days' fighting the 7th had lost its colonel, and 600 of its officers and men had been killed, or wounded. Some companies lost every officer. Lieutenant E. D. Bellew, machine-gun officer of the battalion, continued to serve his gun until it was destroyed, and continued to use relays of loaded rifles until wounded and taken prisoner.

The Canadian line was now strengthened by the King's Own Scottish Borderers, and the 1st Royal West Kents, and the division was further aided by French counterattacks, but the increasing artillery fire of the enemy and their great superiority in numbers rendered the Canadian salient untenable. Retirement was imperative, and fighting every yard of the way the Canadians fell back on St.-Julien. This place being exposed to enemy fire from right and left, a further retirement was necessary. The Third Brigade began a retreat southward. Detachments of the 13th and 14th Battalions were cut off before they could escape from the village. After being surrounded they fought on until their ammunition gave out and all were killed, wounded, or captured.
