British Army organisation

50 Brigades
150 Regiments (= 3 Regiments in a Brigade)
450 Battalions  (= 3 Battalions in a Regiment)
1800 Companies (= 4 Companies in a Battalion)

According to Journey's End that the Younger Orc is watching (he's been studying it as an English set-text), that's a guess at the strength of the British Army in France.

A company I think is conventionally made up of 4 platoons, and I believe that a platoon is generally around 30 men. So, a company would be around 120 men (loosely).

However, this is the post-1913 organisation. This is the organisation that would for example be in use in Transcaspia.

In the later Victorian period, mostly infantry regiments apparently had four battalions, two regular, one reserve and one volunteer, though this could vary quite dramatically.

At present, I have around 90 minis that are vaguely 'Zulu War British', I think. This includes about 12 in Rife Green uniforms with khaki Glengarries (UNIT/Northdale Rifles), about 36 painted up as redcoats (11 are Brigade minis with rebreathers from their GASLIGHT/Steampunk range), and perhaps 10 in khaki jackets. 11 are Dwarves in pith helmets (10 from Old Glory and 1 GW example, that presently are serving as the 'Combined Atlantean Rifle Brigade'). The rest (probably about 20) are currently unpainted. The plan currently involves painting them all as redcoats. I really don't care about the Royal Wessex Regiment and as soon as I get around to it the khaki-jacketed ones will be redcoats too, and they can all be A Company of the 1st Battalion of the Royal North Surreys (except the Dwarves, difficult to see where they fit into that to be honest). The guys in re-breathers can just be regular North Surreys in Martian Expeditionary Force gear. There's no way I'm going at this stage to start faffing about with new units. Sod it. They can all be redcoated soldiers of the Queen and that will be much easier, no matter that some of the officers have newer designs of jacket (more suited to the Boer Wars than the Zulu Wars or Sudan). So, basically (as I think there's about 65-ish) that's half a company.
