On the French front during these days, particularly in the Aisne sector, there was almost continuous fighting in which the Germans displayed dogged determination and reckless bravery, but every attack broke down. On the right bank of the Meuse they were partly successful in an assault on French outposts. Here they penetrated the French center, where they held on for a time, but the French returned in force, and after a struggle of the most sanguinary description in which the opponents fought murderously at close quarters the Germans were forced out and driven back to their lines. North of Verdun the German attacks were especially violent. Here they employed "flame throwers" freely, but were unable to overcome the French resistance or to gain any marked advantage. Wastage of German man power was an outstanding feature of recent engagements on the French front. The combat front of Verdun was held by twelve German divisions, that along the Aisne in 1917 was held by fourteen divisions. During the same period of time from May to September, 1916 and 1917, respectively the Germans engaged along the Verdun front, twenty-five new divisions in 1916; along the Aisne thirty-five new divisions in 1917. The Allied armies had so improved their mechanical means and fighting methods that the Germans were forced to maintain a reserve of at least forty divisions for the safety of their battle line in the west. CHAPTER IV HAIG STRIKES AGAIN AT YPRES--THE FRENCH BREAK THE GERMAN LINES ON THE AISNE The greatest gun duel of the war continued to rage in the region around Ypres in the last days of September, 1917. East of the city the Germans launched six attacks during the day and night on October 1, 1917, against the British lines. Every assault was smashed by the British artillery, rifle, and machine-gun fire. Not since fighting began in this area had such hurricanes of shells and explosives been seen. The Germans gambled against great odds and lost heavily. It was only in Polygon Wood that they obtained the slightest success. Here two small posts were won, but otherwise the British line remained intact. On October 4, 1917, Field Marshal Haig delivered another mighty blow against the German lines east of the Ypres, gaining territory at the most advanced point to a depth of about a mile and a half on a front of more than eight miles. The ground covered by the British assault was from north of Langemarck on the Ypres-Staden railway to a point south of Tower Hamlets, a height south of the Ypres-Menin highroad. The very important system of defenses along the Passchendaele-Gheluvelt road, which the Germans had held so long, was swept over by the victorious British troops.
