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.
