WINTER FIGHTING IN CHAMPAGNE, THE ARGONNE, AND THE VOSGES.
We now come to that part of the French front on which the most successful attempts of the Allies were made during January and February. You have already heard of the little river Suippe, a tributary of the Aisne. Between the upper waters of this river and the Forest of the Argonne there is a chalk plain, dotted with plantations of firs and crossed by rolling downs. In many respects it resembles Salisbury Plain, and for many years has been put to the same use. Before the war it was the great training ground of French troops and the scene of their yearly manoeuvres. The plain is sparsely populated; scattered farms and straggling homesteads are few and far between, and lack of villages means lack of roads. After heavy rain the whole district is a sea of shallow mud; but the ground does not become water-logged, and as soon as the rain ceases the ground dries very quickly. Operations during the winter were therefore possible. General Joffre decided to nibble more vigorously on this plain than elsewhere.
Look at the little map on page [70]. You notice a railway running from Ste. Menehould,[11] on the Aisne at the edge of the Argonne forest, to Rheims. By means of this railway the French troops operating on the plain were supplied with all their needs. The Germans relied on the line which you see running from Grand Pré in the Argonne to Bazancourt. The object of the French was to nibble at the German lines in the hope of pushing back the enemy and seizing this railway. If it could be cut or commanded, the Germans would be obliged to fall back along their whole line. At any rate, a French advance towards the railway would compel the enemy to waste men and shells, and would force him to keep in the region large forces which otherwise would have been sent to the East, where von Hindenburg was badly in need of assistance.
I want you to fix your attention on the little towns of Souain[12] and Perthes,[13] and the farm of Beau Séjour,[14] all of which are marked on the map. Beau Séjour, you will notice, is about 3½ miles east of Perthes. At the beginning of January the French line ran through Souain, south of Perthes and south of Beau Séjour. Almost every day during January the French attacked the German positions. They won a hill to the north of Perthes, which gave them the best gun position in the neighbourhood, and on the 16th of February a general advance began. The Germans held a strong post north of the farm, on a ridge between two little glens. On this ridge they had constructed a fort, which was held by about 500 men.
The French attacked on a plan which was soon to become the regular method of puncturing the German lines all along the Western front. Let me give you some account of this plan—the only possible method of capturing the strongly fortified trenches of the enemy without a terrible loss of life. As you know, the first obstacle to an attack on a line of trenches consists of the barbed wire entanglements which are fixed up in front of them. The attackers are held up by the network of wire, and can be shot down in droves by rifles and machine guns. Then the trench itself has a strong parapet, with loopholes through which the defenders fire on the attackers. For infantry to charge the barbed wire while the parapets are held by an enemy is to court almost certain disaster.
Study the diagram on page [67]. AB is a line of trenches to be attacked, and X is a line of big guns. These guns throw a shower of high explosive shells on to the enemy's trenches. So terrible is the explosion that the barbed wire is blown into a thousand fragments, the parapets are beaten down, the whole trench is utterly wrecked, and the defenders are either killed or wounded, or so stunned by the violence of the bombardment that they cannot make much resistance. When this is done, the gunners lift their sights and lengthen their fuses, and behind the trench create at C a curtain of fire through which no enemy reinforcements can possibly pass. Then the attacking infantry rush forward and occupy the wrecked trench. They work away with their entrenching tools, make a new parapet facing the enemy's second line of trenches, and prepare to beat off counter-attacks. Trenches are thus captured by gun fire alone. You can easily understand that advances made in this way will be slow. Telephone wires have to be laid, ranges calculated, and a thousand details arranged before an assault can be made.
If such an attack is to succeed, two things are necessary. In the first place, the attackers must have many big guns and an almost unlimited supply of ammunition for them; and secondly, they must bring up their guns at X unknown to the enemy, and take him by surprise. If he is able to see the big guns being brought up, he will fire on them before they can be concealed. He will also mass his own guns, and the affair will become an artillery duel on a large scale. Happily, in Champagne the French were able to mass their guns secretly. Their airmen had become so expert that they were able to beat back all the German aircraft that attempted to scout over their lines, while at the same time they could fly over the German lines without much hindrance.
Here is a description of such an attack as seen by a British observer in Champagne:—
"Looking at the battle at a distance of about 2,000 yards from the enemy's lines, the stillness of what one sees is in marked contrast with the turmoil of shells passing overhead. The only movement is the cloud of smoke and earth that marks the burst of a shell. Here and there long white lines are visible when a trench has brought the chalky subsoil up to the top; but the number of trenches seen is very small compared with the number that exist, for one cannot see into the valleys, and the top of the ground is an unhealthy place to choose for sitting in a trench. The woods are pointed out, with the names given them by the soldiers; but it needs field-glasses to see the few stumps that remain when the artillery has done its work. And then a telephone message arrives, saying that the enemy are threatening a counter-attack at a certain point; and three minutes later there is a redoubled whistling of shells. At first one cannot see the result of this fire—the guns are searching the low ground where the enemy's reserves are preparing for the movement; but a little later the ground behind the threatened trenches becomes alive with shell bursts, for the searching has given place to the building up of a wall of fire, through which it is impossible for the foe to pass without enormous loss."
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.
