When a successful attack of this kind is to be made on a large scale, the work of the directing staff must be very perfect. Every trench in the line of attack must be thoroughly shelled at the same time. If certain trenches are left unwrecked, the infantry will be badly mauled when they move forward. Then all the guns of the attacking side must lift their sights and lengthen their fuses before the infantry reach the enemy's trenches, or the men will be caught by their own fire. Everything must work together like a well-oiled machine. A single mistake will be paid for by heavy loss of life.

The French infantry came back into their second line after the action with their bands playing and their colours flying. Their uniforms were covered with mud, and they were as dirty as they could possibly be. Their comrades saluted the colours with love and devotion, and the German prisoners seemed astonished to see such patriotic fervour.]
Such was the general character of the attacks made by the French in Champagne during February. The ridge, which I have already described, was captured by French Colonial troops towards the end of January, after a month's struggle; but elsewhere progress was slow. About five yards a day was the average gain. One by one the little woods and ridges were carried, but as late as 24th March the French were not sufficiently near the railway from Grand Pré to Bazancourt to threaten it seriously. We must not, however, reckon the gains by the amount of ground which was won, but by the number of men which the enemy was obliged to maintain on this part of the front, and by the losses which he suffered. Some five and a half German corps, which were badly needed in the East, had to be massed in Champagne, and their losses were out of all proportion to those suffered by the French. It is said that the Germans lost 10,000 dead and 2,000 prisoners during these attacks. The famous Prussian Guard suffered very heavily at a point about three-quarters of a mile east of Beau Séjour, where two of their regiments were almost wholly destroyed. The Germans themselves admitted that their losses in Champagne were greater than those of the Battle of the Mazurian Lakes,[15] where they had some fourteen army corps engaged.
