There was sharp fighting among the ruins of Puisieux, where the Germans had to be hunted from their hiding places. After this clearing-out process the British line now ran well beyond Gommecourt on the left and down to Irles on the right. The Germans concentrated heavy shell fire on Irles, and showered high explosives on Miraumont and upon other places on the front from which they had withdrawn. The British were now less than a mile from Bapaume, in the rear of which the German guns on railway mountings were firing incessantly on British positions. On March 1, 1917, British headquarters in France, summarizing the operations during February, stated that the British had captured 2,133 German prisoners and occupied either by capture or the withdrawal of the Germans eleven villages. Some of the positions captured were of the highest importance, to which the Germans had clung as long as they could with desperate energy, and from which the British had tried vainly to conquer. The Germans had retired on the Ancre on a front of twelve miles to a depth of two miles. The first stage of the German retirement plan was completed on March 2, 1917, when they made a definite stand, their line now running from Essarts through Achiet-le-Petit to about 1,000 yards southeast of Bapaume. The Loupart Wood occupying high ground along this line had been transformed into a strong field fortress after German methods, and here it was evident every preparation was made for a stiff defense. The British had an enormous task before them in building roads through the recovered ground. The Germans had carefully timed their retirement when the ground was hard, but now owing to a week's thaw most of the Somme and Ancre area was transformed into liquid mud. In addition to the difficulties presented by the terrain, the British patrols in the evacuated territory constantly encountered isolated bodies of German defensive troops who, obedient to their instructions, fought bravely to hold the positions they had been assigned to. Everything that cunning could devise was resorted to to delay the British advance. An Australian patrol discovered in one place a chain stretched across a ravine which was connected with a mine at either end. CHAPTER LVI THE GERMAN RETREAT CONTINUES--FRENCH RECOVER 120 TOWNS The British troops continued to advance in the Ancre area in spite of the difficult terrain and the desperate defense of the Germans who had been left behind in the retirement and who occupied positions where they might work the greatest damage to the pursuers. East of Gommecourt on March 3, 1917, the British gained two-thirds of a mile along a two-mile front. They were also successful east of Bouchavesnes, where they captured the enemy's front and support lines on a front of two-thirds of a mile. In these operations they captured 190 prisoners and five machine guns.
