"Back from hell"

by Samuel Cranston Benson

But the machine guns of the enemy were found to be too formidable and destructive, and as a result of this experience they learned to use the light artillery which could continue its fire even while the attacking party were moving on, advancing as they advanced. The lighter field pieces were placed within a few hundred yards in the rear of the trenches and used to blind the Germans from protecting themselves, as well as to cover the advancing troops until they took the trench. Then the curtain fire was thrown still farther back behind the German line.

This process plainly was a very delicate one, even in its beginning. It seemed a little nervy to order soldiers to advance while above their heads hissed and barked their own gunners' shells. Sometimes these would burst before they got to the curtain line and casualties would inevitably result. It was rather ticklish business for the men to charge forward even if they were a couple of hundred yards behind such a hail of steel.

Soon, however, another improvement was put into effect and that was to shorten the barrage to sixty yards, letting the soldiers advance with the exploding shells nearer and nearer to their own bodies. Of course, there was great advantage in this, as the closer the troops were to the curtain fire ahead, the better they were protected and the shorter was the time after the curtain was lifted until the troops occupied the trench. Cutting this time down to the minimum made it so much harder for the Germans to emerge from their hiding and resist the oncoming troops. The science of this was at last so well worked out that a gap of less than forty yards lay between the curtain and the troops and sometimes only thirty yards which could be covered in a couple of seconds after the barrage was lifted. Time, of course, is the chief element in the endeavor to get the bulge on the other fellow.

Finally the British worked out what they call the "creeping barrage." This takes into account the fact that the trenches are never exactly straight and parallel. But here the camera came to the aid of the Allies and it told them just how much deviation from the parallel there was. From these photographs the relative positions of the trenches at any given point were plotted out accurately, showing the irregular shape of No Man's Land and the variation of its width at all the different places. The Allies then dug identical trenches in the rear and practiced on them. This changed the method of curtain fire from "regular" to "creeping." From that time the barrage started in a line which first followed the shape of our own fire trench, but as it moved forward the configuration was altered and it swayed and wriggled like a snake gradually taking the shape of the enemy's trench. Plainly, it required much deeper skill to employ this method, but its advantages were great. Instead of all the gunners shooting in unison at a single command, each one had a different job to perform in order to make the barrage conform with the angle which the trenches made. This is now the general method and has been brought up to a marvelous degree of accuracy as well as speed.

At practically the same time the creeping barrage was conceived, another idea which has also been extremely useful was developed. This was the second curtain of fire to be thrown in the rear of the enemy's trenches to cut off his retreat and to prevent the coming up of reinforcements. The first curtain covered your advance and hindered his resistance, and the second one beyond him kept new forces from coming to his aid with food, munitions, and information.

The method which is used almost universally in attacking today, then, is this.

Big guns "prepare" the way by hammering the trenches of the enemy and simultaneously driving him to the dugouts and bashing in the trenches which shelter him. Your doughboys then go "over the top" and advance, covered by the curtain fire, at first conforming in shape to their own trenches, and little by little wriggling into the form of the enemy's trenches as it comes nearer to them. Closely following the moving barrage is your infantry. Then another barrage in the enemy's rear is cutting him off from reinforcements and after a time the trench is captured and perhaps many prisoners taken. It is not hard to understand from this modern method of attack what the French general meant when he said, "The artillery conquers, the infantry occupies."
