Fire countermeasures require the calculation of the approximate orientation of the enemy's artillery positions in a very short period of time, based on the trajectory of the enemy's shells, which requires strong mathematical skills.

As early as the mid-18th century, Griboval, the father of French artillery, founded a specialized artillery training school, from which Napoleon graduated. During the reign of Napoleon, Napoleon, who was born as an artilleryman, paid great attention to the cultivation of artillery talents, and the French artillery made great progress and became a branch of the army alongside infantry and cavalry.

Artillery was more difficult to train than infantry and cavalry. A qualified artillery commander will not be less accomplished in mathematics than a university lecturer, and for this reason, artillery is called by many as a "scientist in the arms".

Many of France's high-ranking officers were artillerymen, such as Foch, the commander of Army Group North; For example, Robert Neville, who will soon succeed Joseph Chauffy as commander-in-chief of the French army; Even Xia Fei himself, when he entered the army, the first unit in which he served was artillery.

This reflects the importance that the French attach to artillery, as well as its position in the internal system of the French army.

In the Battle of Verdun three months earlier, the French had repeatedly countered with firepower and knocked out the German artillery positions, thus effectively protecting their own positions. If it were not for the excellent performance of the French artillery, the French would not necessarily have been able to hold Verdun.

Dempsgale was also a professionally trained artillery specialist, otherwise he would not have distinguished himself among the talented French artillerymen as a brigade commander of an artillery brigade.

Under the command of Dempsgayle, the French artillery in a very short time determined the location of the German artillery positions, and then concentrated all the artillery to deliver a covering strike on the German artillery positions.

The effect of the blow was good, and in less than 10 minutes, the artillery of the Germans died down and there was no longer the ability to counterattack.

The planes of the French were still circling in the sky, trying to find the remnants of German artillery. If found, the observer on board the aircraft will indicate the direction and then convey it to the ground artillery unit with carrier pigeons. The French would not have sent bombers unless they were stationary targets, bombers were too fragile relative to fighters, and now aircraft engines were only about 150 horsepower, and if bombs were installed, it was impossible to install thicker armor.

The aircraft is still in its infancy at this point in time, and the current aircraft has a speed of about 150 kilometers per hour and a ceiling of only 4,000 to 5,000 meters.

The war has not stopped to give rise to new technologies, and the "Aircraft Shooting Coordinator" was first used by the Germans last year, and the Fokker fighters equipped with the Aircraft Shooting Coordinator completely controlled the French skies, and the Allied pilots did not survive an average of six weeks on the battlefield, from the autumn of 1915 to the beginning of 1916, a period known as the "Fokker Disaster".

During the war, there were no patents between the rival countries, so the French also installed firing coordinators on their planes, and the sky was once again evenly balanced. Taking into account the strong production capacity of the Entente, the scales of victory had already begun to tilt.

At least in El Becur, where the sky belongs to the French.

The ground here belongs to the Foreign Legion under Qin Zhiyuan.

……

Night, Somme.

The Somme River is not a large river like the Yangtze River or the Yellow River in the usual sense, but a valley similar to a swampy zone, and the channel is only twenty or thirty meters wide.

It was winter, and although it was much more difficult to cross the river, it also made the Germans relax their guard.

On the north bank of the Somme, a force is marching silently. The unit, numbering about 150 people, wore M1914-style helmets with a gray-green wrap wrapped around them, and wore the traditional German iron-gray military uniform, the latest style to be issued this year.

The most distinctive feature of the M1914 helmet is the pistol-tip decoration in the center of the helmet, which makes people instantly recognizable as a German unit, which is significantly different from the helmets of the French and British.

This unit is the special service battalion led by Hu Tingfeng and Greiff.

The special service battalion is the code name proposed by Qin Zhiyuan, which means literally, and it is a "unit performing special tasks".

The force consisted of 50 reconnaissance company soldiers led by Hu Tingfeng, one hundred soldiers of the second battalion selected by Griff, and ten German-French men, who were to take on the task of interspersing behind enemy lines.

Recently, it has been rainy, the ground is full of water, the road is muddy and difficult to walk, and it is impossible to use flashlights for lighting, so the speed of progress is not very fast.

"Can I get to the designated place at the scheduled time?" It was rare for Griff to open his mouth and ask Hu Tingfeng.

The soldiers walked very hard, not that no one would slip and fall to the ground, covered with mud and water, but fortunately, the soldiers were very disciplined, no one complained, and everyone supported each other to move forward in the dark.

"Almost." Hu Tingfeng looked at the sky and gave an uncertain answer.

Cloudy, nothing to see.

Hu Tingfeng wrinkled his nose and sniffed the air, and suddenly clenched his fists and squatted on the ground.

As if given a battle signal, Griff immediately crouched down and alerted the warriors behind him.

Soon, all the warriors were crouching down, like two winding dragons coiled on either side of the road. The warriors raised their guns and pointed their guns at the unknown darkness, ready for battle, ready to meet the possible enemy.

"Dark Whistle! Minimum of two people! Hu Tingfeng pointed to a small forest about forty or fifty meters ago, and whispered in Cliff's ear. This was reconnoitred yesterday, and this is also the farthest point that Hu Tingfeng and their reconnaissance has ever recited.

Greiff nodded, turned back and beckoned a Frenchman to come over, and the two of them put down their long weapons, each with only a pistol and a dagger, and then each took a bottle of brandy, opened it, poured half a bottle on his body, and then took two more sips, hugged each other, humming a slang that no one understood, and walked crookedly on

Our dear ones

It's like from ice water

Give me this poor samurai

A round of sunshine

In the end we didn't freeze

Rehab in a hotel

Let's make our once full purses

It's empty again

……

The Frenchman sang the song of the German mercenaries of the sixteenth century, in German, of course, while Greiff seemed to have drunk too much, and he could not speak in tune, humming along with the song as he staggered forward.

He had not gone far, and just as he was about to reach the grove, Greif seemed to be in a hurry, and unbuckled his belt in the direction of the Somme.

Before the sound of the rustling water had died down, Griff was so drunk that he fell to the ground.

"Ahaha, Bill, you're peeing on your pants...... the Frenchman laughed loudly, and then came over to pull Griff up.

Drunk people are dead and heavy, and it is difficult for a person to pull up, let alone a person who is also about to get drunk. The Frenchman didn't pull it up for a long time, and he couldn't help but start muttering: "Damn, why are you so heavy, who will help me......"

"Bill, wait for me, I'll go back and call someone to carry you......" The Frenchman gave up on Grave and got up to go back to call someone, but he didn't expect to just turn around and fall to the ground, struggling for half a sound and not being able to get up.

"Oh my God, who's going to help me......" In the darkness, the Frenchman's voice was weak and miserable.

"You deserve it, who made you drink so much!" The Dark Sentry finally couldn't help but come out and wanted to help his compatriots.
