May 26. The German regulations for field artillery tactics of March 25, 1889.
It is a new manual of field artillery, very much simplified.
Temporary field fortifications (ended). A new gun of 320 millimeters, Bange system.
The gun was made for the Paris Universal Exposition, and was tested at the proving grounds of the trial committee at Calais. Here are the principal dimensions of the new gun: Length of the piece, 12m.50; total weight, 47 tons; weight of the projectile, 400 kilos; muzzle velocity measured by the Le Boulengé chronograph, 650 meters; velocity at 1500 meters measured by the Le Boulengé chronograph, 590 meters; range measured at an angle of 10 degrees, 9500 meters; maximum range, 19,000 meters; thickness of the iron plate pierced by the projectile at the muzzle, 90 centimeters; thickness of the iron plate pierced by the projectile at a distance of 1500 meters, 75 centimeters; thickness of the steel plate of the greater resistance pierced by the projectile at the muzzle, 60 centimeters; at 1500 meters, 50 centimeters; energy at the muzzle, 8622 meter-tons; height to which this force could raise the gun, 183 meters.
The new French manual of infantry manoeuvres. Title IV, school of battalion. The cavalry armament as viewed by an officer of high rank in the Egyptian army. The musket model, 1886.
Experiments to determine the perforating power of this gun, made at Gavre (the French proving grounds) in June and July, 1888, gave the following results (the table shows the thicknesses of the sundry obstacles stopping the progress of the bullet at various distances). Distances, 10 m., 200 m., 500 m.
| Centimeters. | ||
Pressed coal dust (brignettes) | 22 | 30 | 40 |
Ordinary coal, | 10 | 15 | 30 |
Sand,.............................. | 11 | 45 | 40 |
Earth,............................. | 25 | 45 | 40 |
At 10 meters the coal, sand and earth presented great resistance to penetration. It was also noticed that at that distance the bullets underwent considerable deformations. Penetration increases with the distance; at 200 meters it is greater and the bullets are not deformed; at 500 meters penetration is generally more feeble. It therefore seems to decrease with the force of impact, but only reckoning from a given distance.
This anomaly is owing, apparently, to the irregular rotations that take place on leaving the muzzle.
In the case of other obstacles penetration follows a regular law, increasing with the velocity at the impact, as shown in the following table. Distances, 10 m., 40 m., 200 m., 500 m.
| Millimeters. | |||
Pine, . | 900 | . . | 600 | 150 |
Oak, . | 200 | . . | 280 | 150 |
Sheet iron, | 12 | . . | 6 | 4 |
Sheet of soft steel, | 10 | 9 | 4 | 2 |
Sheet of chromed steel, | . . | 4 | . . | . . |
From the above results, the gun mod. 1886 possesses a perforating power much superior to that of mod. 1874, firing the regulation bullet, or even a hardened lead bullet, at short distance, but this superiority disappears notably as the distance increases.
