We now come to the most vital point of the battle: who was to be the victor in the fight for the WYTSCHAETE-MESSINES ridge? The 6th Bavarian Reserve Division had worked forward by daylight towards WYTSCHAETE, regardless of the heavy artillery fire directed from the high ground on our troops moving up from the valley.[78] At nightfall the left wing of the II Bavarian Corps was still hanging back, unable to break the strong resistance opposed to it, but in spite of this the Bavarian Reserve Division dared to make its attack. The 17th Reserve Infantry Regiment was to enter WYTSCHAETE from the east and the 21st from the south. All the preparations had been carefully made. The men wore white arm-bands as a distinguishing mark when at close quarters with the enemy in the darkness. Water bottles were packed away in the haversacks; rifles were unloaded and bayonets fixed. It was hoped to take the enemy by surprise, and not a light betrayed our arrival in the assembly positions. The hostile artillery fire slackened during the night, but frequent star-shells lighted up the darkness and showed that our opponents were keeping a careful watch. The clear moon must have helped them to see our movements. At 2 A.M. (1st Nov.) the Bavarians advanced from their assembly positions, taking little notice of the enemy's artillery which began to open on them. The general direction of the attack was given by the windmill of Wytschaete, which was clearly outlined in the moonlight against the sky. The 17th Reserve Infantry Regiment under Colonel Hofmann rapidly reached the edge of the village and pushed through to the western exit. The surprise had succeeded, and numbers of the enemy who still held out in isolated ruins were either killed in a hand-to-hand fight, or taken prisoner.[79] Unfortunately, however, our own guns continued to bombard the village, as the news of the victory of the 17th Regiment was not communicated to them sufficiently quickly. At about 6 A.M. Colonel Hofmann therefore decided to withdraw his victorious troops temporarily to the eastern edge of WYTSCHAETE, and to reorganise there. It so happened that the 21st Reserve Regiment arrived on the southern side of the village at this moment, its advance having been delayed by a heavy enfilade fire from the south-west. When the men of the 21st Regiment in the first dim light of dawn saw the figures of men wearing caps running eastwards among the ruins, they immediately opened fire on them. Nevertheless, in spite of the losses incurred through this mistake, the 17th Regiment held its ground at the eastern edge of the village. The error was quickly remedied by singing patriotic songs and by flag-signals, and communication was regained with the neighbouring infantry and with the artillery. A strong counter-attack, however, was now made by six regiments of the XVI French Corps, which had arrived during the night, and the gallant 17th had slowly to withdraw again from the high ground.
