I will try and answer a few of your questions, info mostly from "The Hall Handbook":
The Corps of Artillery consisted of 1699 men, 1531 horses, 48 guns and 132 vehicles and was commanded by a Major-General.
In 1899, the RFA and RFA were organised into Brigade Divisions, the equivalent of modern artillery regiments.These Brigade Divisions are not to be confused with Infantry or Cavalry Brigades and Divisions. A RFA Division commandered by a Lt Colonel comprised 3 Batteries and an Ammunition Column (9 battery ammunition wagons (for the artillery)and 12 small arms ammunition wagons (for the infantry reserves).
A battery of RFA during the ABW consisted of six guns normally 15 pounders, three transport wagons and a field blacksmith. A battery was served by 171 men and 131 horses commanded by a Major. A howitzer battery consisted of six guns served by 195 men with 136 horses.
The Battery consisted of a Left Section (2 guns and 2 ammunition wagons) a Centre Section (2 guns and 2 ammunition wagons)and a Right Section (2 guns and 2 ammunition wagons).
The RGA in the UK at the time of the ABW consisted of:
1)Ten batteries (numbered 1 to 10) of Mountain Artillery. A battery of RGA comprised of four muzzle loaders of 2.5 inch calibre and served by 236 men with 50 horses.
2)Three RGA divisions, designated Eastern, Southern comprising 104 companies, were established in order to defend fortresses or garrisons in Great Britian.
Some of these RGA companies saw service in South Africa, each of which consisted of 146 men, their ordanance consisted of obsolete muzzle loading guns.
The Royal Horse Artillery in the Anglo Boer War consisted of ten batteries of lighter 12 Pounder guns. (numbered A,G,J,M,O,P,Q,R,T, and U).
In general: Drivers were equipped with revolvers only. Gunners were equipped with Sword Bayonets only. Two carbines were fixed to every gun carriage for guard duties only. Depending on the size of the gun it would appear to have been 10 men per RHA and RFA gun and possibly a few more for the larger RGA guns. Multitasking would have taken place when under fire and with the crews taking causualties.
A gun is usually worked by two NCO's and eight gunners. One NCO (known as Gunner 1)leads the gun and is in command of it. Gunner 2 makes ready and fires. Gunner number 3 is assigned the duty of opening and closing the breech block and loading. Gunner number 4 has the important duty of aiming. Gunner number 5 brings in the ammunition box and Gunner number 6 is by the limber and ammunition wagon, these last two are responsible for delivering the ammunition to the guns. Two or three other gunners formed the reserve and remain at the Wagon Line.
The RHA must be remembered supported the Cavalry, the RFA supported the Infantry and the RGA defended forts etc.
This is an interesting collecting field! I did at one time try to get a medal to each battery but as you can imagine it is not an easy task, some of those batteries are almost impossible to find...a long term collecting theme and one must have deep pockets to boot. I still have a few, one of my first medals ever was to a 7th Battery Colenso Gunner, this medal started off my interest in the artillery field..
I will try and keep adding some more info as and when found. Please feel free to ask questions.
