The second regular division (Horne), acting upon the extreme left of the main attack, had two brigades north of the La Bassée Canal and one to the south. The most northern was the 5th (Cochrane's), and its operations really formed part of the subsidiary attacks, and will be treated under that head. South of it was the 6th (Daly's), to the immediate north of the canal. The gas, drifting slowly up the line before a slight southern breeze, had contaminated the air in this quarter, and many of the men were suffering from the effects. None the less, at half-past six the advance was made in a most dashing manner, but the barbed wire defences were found to be only partially damaged and the trenches to be intact, so no progress could be made. The 2nd South Staffords and 1st King's Liverpools on the left and right reached the German position, but in face of a murderous fire were unable to make good their hold, and were {180} eventually forced back to their own trenches after enduring heavy losses, shared in a lesser degree by the 1st Rifles and 1st Berks in support. Upon their right, south of the canal, was the 19th Brigade (Robertson). The two leading regiments, the 1st Middlesex and 2nd Argylls, sprang from the trenches and rushed across the intervening space, only to find themselves faced by unbroken and impassable wire. For some reason, probably the slope of the ground, the artillery had produced an imperfect effect upon the defences of the enemy in the whole sector attacked by the Second Division, and if there is one axiom more clearly established than another during this war, it is that no human heroism can carry troops through uncut wire. They will most surely be shot down faster than they can cut the strands. The two battalions lay all day, from morning till dusk, in front of this impenetrable obstacle, lashed and scourged by every sort of fire, and losing heavily. Two companies of the 2nd Welsh Fusiliers, who gallantly charged forward to support them, shared their tragic experience. It was only under the cover of dusk that the survivors were able to get back, having done nothing save all that men could do. Their difficult situation was rendered more desperate by the fact that the wind drifted the gas--that filthy and treacherous ally--over a portion of the line, and some of our soldiers were poisoned by the effects. The hold-up was the more unfortunate, as it left the Germans the power to outflank the whole advance, and many of the future difficulties arose from the fact that the enemy's guns were still working from Auchy and other points on the left rear of the advancing troops. In justice to the Second Division, {181} it must be remembered that they were faced by the notoriously strong position called "the railway triangle," and also that it is on the flanking units that the strain must especially fall, as was shown equally clearly upon the same day in the great French advance in Champagne.
