Field service regulations for quick-firing mountain artillery

 

 

 

 

Field service in mountain artillery was covered in the manual Устав за строевата служба в планинската скорострелна артилерия (Field service regulations for the quick firing mountain artillery) published in 1906 and adopted with amendments and additions in 1909. It was an adaptation of the French Règlement de manovre de l’artillerie de montagne published on 25 August 1905 that however referred to the De Bange not quick firing guns.

The Regulations dealt with the quick-firing guns, but gave also some instructions about the employment of the old not quick-firing guns on the new conditions, in order to allow training for both kinds of mountain gun according with only one normative text. However, initially it only dealt with the Krupp QF gun, the rules relating to the Schneider gun purchased in 1907 were added later.

The text included both the gun and the battery training and in a series of appendices, it briefly dealt with the signals and conventional signs used by the mountain artillery, how to compile a line report and how to handle the sabre on horseback.

 

Composition and subdivision of the units

The 75mm QF mountain battery is organized as follows :

    fighting battery : 4 guns, 8 ammunition loads with two boxes with 8 shells each, 1 load with platoon bags, 1 load with entrenching tools – it is divided into two platoons, whose commanders are two officers, the senior one commanding the first platoon, or by feuerwerkers (sergeants);

    battery reserve : 24 ammunition loads with two boxes with 8 shells each, 2 loads with pack forge, 1 load with drugs and bandage for men and horses, 1 load with horses equipment, reserve troops, reserve horses, hors rang troops – it is subdivided in two platoons, the battery reserve commander is a senior feuerwerker, the platoon commanders are feuerwerkers;

    transport train : 3 loads for bags, 1 load for water flasks, 8 loads for forage, 2 loads for the officers baggage, 2 loads for field kitchens, 3 loads for food supply, 1 load for spare horseshoes and boots, 1 load for carpenter and saddler tools, 1 load for chancery, reserve troops, reserve horses – the transport head is a feuerwerker.

Every battery carries 8 Linnemann spades, 8 picks, 8 hatchets and 2 axes as entrenching tools. In order to provide communication between the units every battery has 4 field telephones with 500 metres of cables each. Every mountain artillery regiment had 3 Goerz rangefinders, 1 for every artillery division. Mountain artillery, like field artillery, has introduced battery telescopes, dial sights and mechanical fuze setters.

 

The Q.F. mountain artillery piece (оръдие, pièce) is commanded by a NCO, the gun head (оръдейния начанлик, chief de pièce), and is attended by six gunners (прислужници, servants):

    two shell-handlers (раклен, pourvoyeur), standing near the second loaded hors, bring the boxes full of shells to the firing position and take away the empty ones;

    the fuze-cutter (поставач, déboucheur) sets the fuze and gave the cartridges to the loader;

    the loader (пълнач, chargeur) is the deputy of the aimer and puts the cartridge into the chamber;

    the firer (стрелец, tireur) opens and closes the breech-block, fires and removes the cartridge-cases with the brush;

    the aimer (мерач, pointeur) points and aims the gun using the different measuring devices: he must be able to arrange and remove the measuring device from the gun, give the height of the bar sight, give and correct the deviations on the dial plate and the drum, give the deviation on the lateral adjustments mechanism, set the level and the vernier, make the required corrections on the level, direct the gun line of sight at the assigned mark, measure the angle of sight on the level, place the extended joints of the bar sight, use the quadrant to measure the slope of the axis and to take or give the angle of departure, when the level lacks.

 

The gun head supervises the functioning of the materials, the correct and timely action of the gunners, and the constant replenishment of the gun with shells. He gives the initial and rough direction of the gun by acting on the traversing lever and drives the spade into the ground, doing the same even when changing targets, when firing at moving targets, and when aiming them is impossible without changing the trail. Furthermore, he puts the ring to the commanded sight graduation. While shooting, he kneels behind the firer.

Before opening fire, the shell-handlers place two ammunition boxes on the left side of the fuze-setter – one behind the other, with the chains to the muzzle of the gun and then stand to one side of the gun. The aimer places the bags with the measuring instruments to the right of the gun head, who orders place them on the gun.

 

 

Route formation

The gun can be towed by two horses or transported by pack animals dismantled in four loads. The mountain artillery moves only at walk: 4 km in an hour on flat ground, in mountainous terrain the speed of movement depends on the ground.

During the march, the gun and its six pack animals usually advance in succession, one after other, and they are preceded by the gun head. The detachment was composed by six horses drivers and six gunners. The order of succession of the loads is : carriage, wheels, barrel, cradle and the two ammunition boxes.

Usually the battery must be unpacked in a covered position and the gun are carried to the firing line by the gunners. If the ground does not allow the deploying of the guns in the prescribed way, every gun is carried to the best position separately.

For mountain artillery, usually native ponies are employed. Mules are not much used in Bulgaria, being regarded as vicious and troublesome. Donkeys are largely employed for carrying light loads.

Battle formation

In battle formation, the guns are deployed side by side at spaces of 40 paces (full interval), 20 paces (narrow) or 10 paces (close). However, if necessary, the battery commander can also set different intervals.

 

The gun and ammunition horses of the fighting battery are placed behind some cover to the side or rear of the battery, no further than 150 paces, the formation depending on the cover. Without good and secure cover, they are placed 150 paces behind and 50 paces to the sides of the flank of the battery. The platoon bags are left 20 paces behind the battery.

 

The battery reserve is in a covered position at 150 / 500 paces behind the battery and the transport train is near this detachment.

 

The manual stresses that it is important to pay attention to have a good observation point near the firing line, since the effectiveness of the fire greatly hangs on it.
