It was clear on the morning of April 24 that the advanced angle, where the French and Canadians had been torn apart, could no longer be held in face of the tremendous shell-fire which was directed upon it and the continuous pressure of the infantry attacks. The 3rd Canadian Brigade fell slowly back upon the village of St. Julien. This they endeavoured to hold, but a concentrated fire rained upon it from several sides and the retreat continued. A detachment of the 13th and 14th Canadians were cut off before they could get clear, and surrounded in the village. Here they held out as long as their cartridges allowed, but were finally all killed, wounded, and taken. The prisoners are said to have amounted to 700 men. The remainder of the heroic and decimated 3rd Brigade rallied to the south of St. Julien, but their retirement had exposed the flank of the 2nd Canadian Brigade (Curry's), even as their own flank had been exposed by the retirement of the French Forty-fifth Division. This 2nd Brigade flung back its left flank in order to meet the situation, and successfully held its ground. [Sidenote: The arrival of reinforcements.] In doing this they were greatly aided by supports which came from the rear. This welcome reinforcement consisted of three battalions of the 84th Brigade, {60} under Colonel Wallace. These three battalions were ordered to advance about four o'clock in the afternoon, their instructions being to make straight for Fortuin. Their assault was a desperate one, since there was inadequate artillery support, and they had to cross two miles of open ground under a dreadful fire. They went forward in the open British formation--the 1st Suffolks in the van, then the 12th London Rangers, and behind them the 1st Monmouths. Numerous gassed Canadians covered the ground over which they advanced. The losses were very heavy, several hundred in the Suffolks alone, but they reached a point within a few hundred yards of the enemy, where they joined hands with the few Canadians who were left alive in those trenches. They hailed their advent with cheers. The whole line lay down at this point, being unable to get farther, and they were joined at a later date by the 9th Durhams, who came up on the right. This body, which may be called Wallace's detachment, remained in this position during the night, and were exposed to severe attack next day, as will be seen later. So perilous was their position at the time the 9th Durhams came up that preparations had been made for destroying all confidential records in view of the imminent danger of being overwhelmed.
