Just by way of background, that'll be Major PHS (Percy) Barrow who was a very fine cavalryman indeed. He commanded a MI squadron in the AZW and fought at Inyezane and Gingindlovu. After the Transvaal rebellion he became second in command (as a Lt Col with seniority 25/7/83) of the 19th H. He participated in the charge of the cavalry brigade at El Teb, commanding the second line, but was severely wounded, unhorsed and about to be done to death, when Quartermaster Sergeant William Marshall plucked him to safety, earning himself the VC in the process. (Barrow - MID and CB for the campaign). His boss on this occasion was Colonel Herbert Stewart, who had also been in the Transvaal, as Colley's COS (WIA and PW at Majuba). Later in the year Barrow was back in action with the Desert Column for the Gordon Relief expedition, commanding a squadron and a half of the 19th H. The column was commanded by the now Brig-Gen Sir Herbert Stewart, (who was only a substantive major in his regiment by the way). The squadron commander for the 19th was Major JDP French who went on to command the BEF in 1914. The 19th H did particulalry well as the eyes and ears of the column; much to do with Barrow's horse management, as well as his tactical handling of his command. Sad to say, although he lived through the Nile expedition, Barrow was to die of his El Teb wound a couple of years later.
The MI detachment at Laing's Nek and Ingogo was commanded by Maj Brownlow 1st KDG, who had been left behind with his regiment's rear details after the main body had rather inopportunely sailed for home. (They had earlier been committed to the AZW of course). There were no other substantive engagements to speak of involving MI in the campaign - except in so far as some of them might have been involved in covering the retreat from Majuba, but I cannot recall any direct reference to them doing so. Most of the uncommitted troops simply stood to their arms at Mount Prospect in anticipation of a follow up attack from the Boers. Barrow is certainly credited with service in the Transvaal campaign, but according to Hart's 1884 'under Sir Evelyn Wood', which tends to suggest that he might not have arrived before Majuba (Colley KIA, Wood assumes) - although I wouldn't swear to this. If he made it, it would have been tight anyway, suggesting that the majority of the time was passed in post-Majuba ceasefire mode.
Interesting man Barrow. His brother Charles (Maj C.T. Barrow) was in the Scottish Rifles (Cameronians) and was also in the Desert Column, serving in the Mounted Infantry Camel Regiment (MICR), which he commanded at the battle of Abu Klea, after the regimental commander (Gough) was 'knocked senseless' by a spent round.
