3. ARTILLERY

Artillery is of many descriptions, differing in the guns they use, and their functions in war. Only that brought into the field with an army, as distinguished from Siege, Fortress, and Coast Artillery, will be here described. It may be divided into Field Artillery, Heavy Artillery, and Mountain Artillery.

FIELD ARTILLERY

Field Artillery in the most general sense means the Mounted Branch of the Arm, which possesses mobility, so as to accompany the other Arms. Its personnel does not march on foot, so that the guns can move at a pace beyond the walk, when desired. It comprises Field Artillery proper, or that armed with the Field Gun (or Field Howitzer) and Horse Artillery.

Field Guns form the larger portion of all Artillery in the field. They fire mainly shrapnel, or shell containing small round bullets which are very effective against the enemy’s men and horses, but useless against material objects. In foreign armies they have therefore a small amount of shell filled with high explosive, in addition to the shrapnel.

Field Howitzers use high-angle fire, giving a large angle of descent, so that they can search out the enemy’s trenches. They are provided with high-explosive shell in addition to shrapnel, so as to destroy masonry and field works, which the shrapnel of field guns cannot injure.

Both these varieties of Field Artillery have their Officers and Sergeants mounted, and carry their men seated on the gun limbers, or on the wagons, so that they can move at a trot.

Horse Artillery is provided for supporting Cavalry in action. It is armed with a lighter nature of field gun, and has its personnel mounted, so as to be very mobile. It can keep up with Cavalry both on the march and in action, and can move at the gallop when required.

HEAVY ARTILLERY

This comprises the heaviest guns and howitzers having sufficient mobility to accompany an army in the field. It uses shell filled with a high explosive, as well as a large shrapnel, and is therefore effective against field works and masonry as well as against men and horses. It differs from Field Artillery in having less mobility, but longer range and much greater effect. It generally comes into action at long ranges, and changes its position as little as possible in action. It will be very effective against the enemy’s artillery and field works, and its great range will allow it to bring oblique fire on the vital portions of his line.

Heavy Artillery is manned by the non-mounted Branch, called Garrison Artillery in England, and Foot Artillery abroad. It requires eight-horse teams, and moves only at a walk, the men marching on foot.

MOUNTAIN ARTILLERY

Artillery carried on pack animals is used in hilly, enclosed, or rough country, where wheels cannot pass. It is the weakest form of Artillery in shell-power, as it is armed with a light gun, which can be carried on a pack mule. A heavier gun can be carried, if formed of two parts, each about 200 lb. weight, or a load for one mule, which can be jointed together for action. The gun carriages, ammunition, and stores are also carried on mules, and the personnel marches on foot, and is provided from the “Foot” (or “Garrison”) Artillery. The slowness of Mountain compared to Field Artillery is compensated in broken country by its ability to take cover, and to come into action in places inaccessible to Field Guns, so that it can support Infantry more closely.

THE BATTERY

The Tactical Unit of Artillery is the Battery, of 4, 6, or 8 guns, with 1 to 3 Ammunition Wagons to each gun. Field guns and wagons have six-horse teams; Heavy Artillery has eight-horse teams.

In France, Switzerland, Turkey and the United States all Batteries are of 4 guns.

In other armies all Field and Horse Artillery Batteries are of 6 guns, except in Austria, where Horse Artillery has 4-gun Batteries, and in Russia, where Field Batteries have 8 guns.

Heavy Batteries have generally 4 guns, owing to the number of wagons required to carry a sufficient amount of their heavy ammunition.

Mountain Batteries have 4 guns, except in Russia, where they have 8.

The Battery in all armies has a strength of from 130 to 200 men and horses. It is divided into Sections of 2 guns with their wagons, commanded by a Lieutenant, and these into Sub-Sections under a Sergeant. The Battery Commander is a Captain, except in the Russian Service, where he is a Lieutenant-Colonel, and in the British Service, where he is a Major, with a Captain as Second-in-Command to take charge of the Ammunition Supply in action. To assist the Battery Commander in action, he has a Staff comprising trumpeters, rangetakers, observers, signallers, mounted orderlies, scouts, and horse-holders. There is also a small Administrative Staff, including artificers for repair of harness and carriages.

THE ARTILLERY BRIGADE

Batteries are grouped into larger Units, called in the British Service Brigades. They are commanded by a Lieutenant-Colonel, with an Adjutant, and a Staff for purposes of observation and command, including telephone and signalling detachments, rangetakers, and orderlies. This Unit is called an Abteilung in Germany, a Groupe in France, a Division in Russia and Austria, and a Battalion in Japan and the United States. It comprises as a rule three batteries of Field Guns, or of Howitzers (or two batteries of Horse Artillery), with an Ammunition Column. Heavy Batteries in the British Service are not brigaded, but one, with its own Ammunition Column, forms part of the Artillery of each Division. In foreign armies they are grouped by twos or fours into Battalions.

HIGHER UNITS OF ARTILLERY

In foreign armies the above Units of three batteries are grouped by pairs into Artillery Regiments, commanded by a Colonel with a Staff. The Divisional Artillery and the Corps Artillery are respectively formed of one or more Regiments.

Two Artillery Regiments are in some armies grouped into an Artillery Brigade, which forms the Divisional or Corps Artillery, and is commanded by a General with a Staff.

AMMUNITION COLUMNS

Ammunition Columns form an integral part of the Artillery, but they carry ammunition for Infantry as well as for the guns. They are Fighting Units, because the replenishment of ammunition is a function of the Fighting Troops, and the movements of Ammunition Columns are tactical operations. The Ammunition Columns belonging to Units of Artillery provide the first reserve of ammunition. The second reserve of ammunition is provided by Divisional Ammunition Columns, which in foreign armies form the Divisional Ammunition Park. There is in large armies also an Army Corps Ammunition Park comprising several Columns, and an Army Ammunition Park, behind which are the Ammunition Depôts on the L. of C.

The Ammunition Columns constitute also a reserve to draw on for officers, men, teams, and matériel, to replace the losses of the Batteries. In Manchuria, the men of the Ammunition Columns were, within twelve months, all absorbed by the Batteries.

An Ammunition Column comprises about 150 to 200 men and as many horses, with from 20 to 30 ammunition wagons.

BRITISH AMMUNITION SUPPLY

In the British Service the organization of the Ammunition Supply is as follows:

The Field Battery and Horse Artillery ammunition wagons carry 176 rounds per gun, those of a Howitzer Battery 88, and of a Heavy Battery 76 rounds per gun.

The Ammunition Column of each Field Artillery Brigade carries 200 rounds per gun for its Brigade. It carries also rifle ammunition (100 rounds per rifle) for one Infantry Brigade. The Horse Artillery Ammunition Column carries a supply of rifle ammunition (100 rounds per rifle) for the Mounted Troops, in addition to gun ammunition at the rate of 220 rounds per gun.

The Ammunition Column of a Howitzer Brigade, and that of a Heavy Battery, which have to carry heavier gun-ammunition, at the rate of 70 and 98 rounds per gun respectively, carry no rifle ammunition.

The Divisional Ammunition Column is divided into 4 Sections, giving three for the three Field Artillery Brigades (carrying 120 rounds per gun), and one Section with ammunition for the Howitzer Brigade (92 rounds per gun) and for the Heavy Battery (80 rounds per gun), and also for a proportion of the guns with the Mounted Troops. Each of the first three Sections carries a reserve of 100 rounds per rifle for one Infantry Brigade. The fourth Section, having heavier gun-ammunition to carry, is not burdened with any rifle ammunition.
