As the great momentum forced the German advance through the allied lines into the open field beyond and was joined by a heavy column, which had debouched from the vicinity of Auchy, British guns opened a murderous fire and inflicted terrible slaughter upon these ranks.
The Coldstream and the Scots Guards retreated to their second line of defense, where they joined others of their command held in reserve there. Once again they turned to meet the oncoming Germans, and again were forced to give way, leaving the Germans in possession of all the ground previously gained. The remnants of the Guards retreated until they were met by the London-Scottish regiment sent to reenforce them. Here they halted while a counterattack was being organized by the First Royal Highlanders, part of the Camerons, and the Second King's Rifle Corps which also came up.
At one o'clock on January 25, 1915, and with the cooperation of the French on their right, this rapidly improvised force moved forward, making unobstructed progress on their wings by the canal and the road. For some reason their center was delayed and held back. When they did finally arrive and pressed forward with a rush to meet the German forces, who were ready to receive them, the impact was fearful, and the casualties on both sides enormous; but no gains were made by the Allies, and the Germans held the ground they had won. At the height of the battle the Second Royal Sussex rushed into the fray in support of their hard-pressed comrades, but all to no purpose, for these as the others were forced back to the rear of their starting point with but a fraction of their forces remaining to report the events of the day.
While this terrible slaughter was in progress, the French left on the other side of La Bassée road, which separated the Allies at this point, had been attacked by the right of the German line, and driven back to a considerable distance, but not as far back as the British, so that the French left was in advance of the British right and badly exposed to flank attack from the northward.
This obliged the entire allied forces to retreat some distance farther to the rear, and as night came on and the severity of the action had ceased, the Allies had an opportunity to realign their positions and somewhat strengthen the same by the First Guard Brigade which now came up, showing the terrible suffering to which they had been subjected. Finally, however, it was found advisable to withdraw the Guard altogether and replace them by the First Infantry Brigade.
Now the German tactical idea became clear. It was to force the British to concentrate on the exposed line between Festubert and Givenchy, north of the canal, and then to turn the British right by the German forces in their new position just south of the canal, thus calling for simultaneous action on both sides of the canal.
The Germans delivered an equally severe attack upon the allied position in the village of Givenchy, about a mile north of the canal, which bounded the scene of the attack just described. As in the other attack, the Germans opened action by severe artillery fire, using high-explosive shells, and after due preparation, at about 8.15 in the morning, the infantry advanced, as is customary with the Germans, in close formation. The British met this advance by somewhat weak artillery fire, which, it was afterward explained was due to continued interruption of the telephonic communications between the observers and the batteries in the fight. However, as it was, this fire, added to the machine gun and rifle fire from the trenches, served to turn the German advance from their original direction, with the result that they crowded together in the northeast corner of Givenchy after passing over the first-line trenches of the Allies' front. Their momentum carried the Germans far into the center of the village, with remarkably few casualties considering the murderous fire to which they had been subjected throughout their impetuous advances.
In the village of Givenchy, however, the Second Welsh Regiment and the First South Wales Borderers, which had been stationed there and held in reserve, gave the Germans a warm reception, and when the First Royal Highlanders came up they delivered a fierce counterattack. In this they were supported by the fire of the French artillery, which assistance, however, proved costly to the Allies, as the French fire and bursting shells killed friend and foe alike. Street fighting became savage, amid the explosions of shells sent to enliven the occasion by the French. This concluded the action for the day and when the smoke cleared away both sides found their position comparatively little changed and nothing but the thinned ranks of the combatants reminded the observer that the most severe kind of fighting had taken place for the best part of a day.
The following day, January 26, 1915, the action was resumed, and the attack opened along the Bethune and La Bassée road. This soon died out, as though by general consent, each side reoccupying their position of the previous evening.
But on Friday, January 29, 1915, early in the morning, the Germans again opened with severe artillery fire which directed its attention particularly to the British line, where the First Army Corps lay between La Bassée Canal and the Bethune road near Cutchy. After an hour's shelling the Germans sent one battalion of the Fourteenth Corps toward the redoubt, and two battalions of the same corps were sent to the north and south of this redoubt. Now upon this point and to the north of it stood the Sussex Regiment and to the south of it the Northamptonshire Regiment. The attack was severe, but the defense was equal to it and the net results were summed up in the casualty lists on both sides. An attack upon the French, south of Bethune, on the same day met with like results. The great German objective was to open another road to Dunkirk and Calais, and had they been successful in the engagements of the past few days it is probable that they would have succeeded.
