British army, the German forces from Antwerp concentrating westwards in ever increasing numbers. By the 15th Capper's 7th Division was east of Ypres, while Byng's 3rd Cavalry Division, a day earlier, had connected up with Gough's 2nd Cavalry Division in front of Kemmel and assisted in the capture of that position, a gain which proved of the utmost importance in the subsequent struggle for Ypres. Allenby's Cavalry Corps had greatly distinguished itself during the two previous days, driving the enemy back all the way in a magnificent sweep to the north and north-east.
A brilliant series of advances by Pulteney's 3rd Corps on 12-15th Oct., leading to the capture of Bailleul and Meteren, and the line Sailly-Nieppe, confirmed French in the belief which he shared with Foch that the enemy had exhausted his strength, and that the time was ripe for a strong offensive eastwards. The advance had scarcely been started, however, before reports arrived of a powerful offensive on the part of the Germans towards Ypres and the Yser. The power and weight of the enemy's opposition on the British front increased each day. Armentières and the Bois Grenier were won by 15th Oct., but the failure of the 4th Corps in its advance on Menin was one of numerous indications that the Germans were being heavily reinforced. By the 21st all General French's worst forebodings were realized by the certainty established that the small German force which had been operating between Ostend and Menin on the 18th had been increased by no fewer than four corps. This discovery, in the British Commander-in-Chief's own words, "came like a veritable bolt from the blue". There was no longer any hope of continuing the offensive on the part of the comparatively weak British line, extended as it was on too long a front. It was a case of holding on now until relief arrived.
The threat was twofold. Not only were the Germans massing in tremendous strength in the north; they were also seriously threatening the British right. Maud'huy, round Arras, was fighting a battle which, like that which the British were waging round Ypres, was one of the landmarks of the war. He sent word on the 16th that the enemy was intent on driving in a wedge between Ypres and La Bassée—a threat which, had it matured, would have finally separated the Allies, and compelled the British either to surrender or be driven into the sea. Faced by this double threat, General French decided to risk the possible disaster on his right, and concentrate against the German tide in the north, which otherwise must gain the seaboard, with possibly fatal consequences to the whole British campaign.
Fortunately the First Army under Haig had already been ordered in the direction best calculated to meet the new situation, though there was no longer any hope of its original orders—to turn the enemy's flank and drive him back to Ghent—being carried out. In this first phase of the battle of Ypres, which lasted until the night of 26th Oct., the northern portion of the British line, notwithstanding the enemy's immense reinforcements, progressed slowly but surely, and took heavy toll in killed, wounded, and prisoners. A certain amount of ground was lost to the south, between Zonnebeke and La Bassée—the commanders of both the 2nd and 3rd Corps being anxious about their positions on more than one occasion—but at no point was any serious break made in the line. Maud'huy at the same time was gallantly keeping the enemy in check in the Arras region, though he could not drive him from Lens and the Vimy Ridge; while on the left the French and Belgians were withstanding repeated assaults on the swaying front between Dixmude and the sea. The line held, and was now more or less firmly established.
The second phase of the battle of Ypres consisted in the repeated attempts of the Germans to break through this line at all costs. It began on 27th Oct., and lasted through five of the most momentous days in the history of the British army. On this day the French 9th Corps, which had been sent by Joffre to the assistance of the sorely tried British troops, took over the trenches in the northern part of the British salient. Capper's 7th Division, exhausted by incessant fighting and fearful losses, was temporarily attached to Haig's 1st Corps in the centre, and took over the ground south of the Ypres-Menin road. Byng's 3rd Cavalry Division was at the same time placed under Allenby. The 4th Corps was thus temporarily broken up, Rawlinson being sent home to supervise the preparation of the 8th Division for France.
The British line was further reduced in numbers during the opening days of this new phase of the battle by the repeated but unavailing attempt of the enemy to advance, the Germans meantime mounting up reserves of reinforcements for a decisive blow until, by the 30th, they outnumbered the battle-worn British by two to one. Then came the onslaught in full, almost overpowering strength. "October 31st and November 1st", afterwards wrote the British Commander-in-Chief in his story of 1914, "will remain for ever memorable in the history of our country, for during those two days, no more than one thin and straggling line of tired-out British soldiers stood between the Empire and its practical ruin as an independent first-class Power." The storm centre of the British
battle-line was the Wytschaete-Messines ridge, where Allenby's Cavalry Corps and Shaw's 9th Brigade of the 3rd Division withstood for forty-eight hours the supreme efforts of two and a half German army corps to dislodge them. The honours of those heroic days were shared by the French 9th Corps and the British 1st Corps (with the 7th Division attached) in their continued defence of the Ypres salient; and the British 2nd Corps, which held a long line on the right in difficult country, and, though forced to give up Neuve Chapelle on the 28th, withstood repeated attacks by superior numbers until the Indian Corps took over their positions.
