The First Division had taken the place of the Twenty-third after the fall of Contalmaison, and had pushed its way up until it was level with the line of {161} their comrades on the right, whence in the manner described at the end of the last chapter they drove their line forward upon July 15. On the 20th they received a rebuff, however, the 1st Northants being held up by a very formidable German trench called Munster Alley. The ground already gained was consolidated, however, and the division lay with its left touching the Australians on the right of Gough's army, and its right connected with the Thirty-third Division, whose doings at High Wood will presently be considered. For the purpose of continuity of narrative it will be best to continue with a short summary of the doings of the First Division upon the left wing of the advance, their general task being to hold that flank against German counter-attacks, and to push forward wherever possible. It was continuous hard work which, like so many of these operations, could gain little credit, since there was no fixed point but only a maze of trenches in front of them. The storming of a nameless ditch may well call for as high military virtue as the taking of a historic village, and yet it seems a slighter thing in the lines of a bulletin. Munster Alley and the great Switch Line faced the First Division, two most formidable obstacles. On July 23, in the early morning, the 2nd Brigade of the First Division attacked the Switch Line, in conjunction with the Australians, on the left, and the Nineteenth Division to the right. The attack was held up, Colonel Bircham of the 2nd Rifles and many officers and men being killed. Colonel Bircham was a particularly gallant officer, who exposed himself fearlessly upon every occasion, and it is on record that when remonstrated with by his adjutant for his reckless disregard {162} of danger, he answered, "You know as well as I do where a colonel of the 60th ought to be." Such lives are an example and such deaths an inspiration. Altogether the 2nd Rifles lost about 250 men in this night attack, and the other first line battalions--the 2nd Sussex, 10th Gloucesters, and 1st Cameron Highlanders--were all hard hit. The failure seems to have been partly due to misdirection in the dark. Upon July 25 the 1st South Wales Borderers of the 3rd Brigade attacked Munster Alley, but were again unable to get forward on account of the machine-guns. Nothing daunted, the 2nd Welsh had another fling at Munster Alley next day, and actually took it, but had not weight enough to consolidate and to hold it. On the other hand, the British line was held inviolate, and a strong German attack upon July 25 towards Pozières was repulsed with loss.
