On the 10th, an interesting operation was carried out by the British. The front attacked was shorter than in the offensive of July 31, and extended about a mile and a half to the south of the Ypres-Roulers Road. Early in the morning the British were in complete possession of Westhoek Village, after which a violent struggle took place for the high ground round the village. By evening all the objectives had been attained, including the capture of Westhoek Crest and Glencorse Wood. August 12 was marked by six enemy counter-attacks, which caused a slight withdrawal of the line to the south of Glencorse Wood. Everywhere else the Allies' positions were fully maintained. =Second Phase= (_August 15--September 19, 1917._) The Allies resumed their offensive on August 15 along a front of some nine miles, from the Yser Canal to the Ypres-Menin Road. The attack began at 4.45 a.m. The French attacked on both sides of the Steenstraat-Dixmude Road, crossing the Steenbeek stream in the morning. Driegrachten Bridgehead was taken after hand-to-hand fighting, while in the evening the whole of the strip of ground between the Yser and the Martjet-Vaart Canal was in the hands of the French. The British operating on the right of the French rapidly attained their first objectives, then vigorously following up this first success, they took by assault the village of Langemarck and its strong defences, advanced 800 yards beyond the village and captured the whole system of trenches. To the south, along the Ypres-Menin Road, the struggle was more stubborn, the Germans resisting desperately. A series of furious counter-attacks enabled them finally to preserve their line practically intact in this district. The day's captures included more than 2,000 prisoners, of whom thirty were officers, and twenty-four guns, including several of large calibre. Desperate fighting continued until September 19 without, however, altering the positions established on August 15. On August 19, the British, by small local attacks, advanced about 500 yards on the Ypres-Poelcappelle Road and captured several fortified farms. The Germans made desperate efforts to hold the high wooded ground comprising Polygone and Inverness Woods, near the Ypres-Roulers Road. On the 22nd the fighting increased in fierceness. The British advanced only with great difficulty, and the eastern edges of Inverness Wood were hotly contested. In these combats, from which neither side gained any decisive advantage, the Germans made use for the first time of liquid fire, thanks to which innovation they succeeded temporarily in retaking the north-western corner of Inverness Wood, but were soon driven out. [Illustration: SECOND STAGE: THE ATTACK OF AUGUST 15 (15/8)] Further north, the British, on August 24 and 25, advanced their lines to the north of St. Julien and Langemarck.
