From "Promotion by Brevet", by Maj. Gen. F. S. G. Piggott, Colonel Commandant, R.E., in: Army Quarterly 58 (1949), p. 97-104.
(Promotion by Brevet was substantive promotion in the army, but not in the corps, i.e. usually the regiment. It was introduced by Wellington in the Peninsula campaign and became a Royal Prerogative under G IV.)
...
"Young officers ... were taught how to solve some of the problems that arose from the operation of the brevet system. For example : Major (1910) and Brevet Lieut-Colonel (1913) A., with Major B. (1908), both gunners, leave their barracks in uniform and walk to call on a neighbouring infantry battalion. Who takes the sentry's salute on leaving the artillery barracks, while walking through the town, and when entering the infantry barracks, respectively? The answer is Major B. on leaving, and Lieut-Colonel A. in the town and on arriving at the infantry barracks. Elementary, of course ..." (p. 98; I *love* that last comment. [:p])
"The best-known anomaly of all, which intrigued everyone, was the case of the major of an infantry battalion with a brevet lieut.-colonelcy of an earlier date than that of the substantive rank of each of the commanding officers of the brigade. Naturally he took command of the brigade when the brigadier was away, as he was the senior officer, <i>in the army</i>, in the brigade." (p. 99)
And on the further complication of "delayed action", where subalterns were given brevets to become effective after their promotion to a field officer rank:
"There was one remarkable instance of this in the First World War which, from memory, ran as follows in the <i>London Gazette</i>: 'Lieutenant (acting Lieut.-Colonel) (temporary Brigadier-General) D. to be brevet Major on promotion to the rank of Captain.'
In this multiplicity of ranks the brevet system introduced an element of stability ..." (p. 99; I can only imagine!! [:D])
How these people ever got to run an Empire is sometimes beyond me. [8D]
