During the march, and whenever the country would admit of such formation, the leading corps halted, and the extended line of march was curtailed by the succeeding regiment forming upon its left; waggons came up in a sort of deployment into line, and certain simple movements were practised which would be carried out in case of sudden attack. Lord Chelmsford invariably made a great point of concentrating his waggons whenever the slightest opportunity offered. General Newdigate and General Wood between them had 900 waggons, and it may easily be imagined what a column 450 of these would make. Allowing 30 yards to each--and that is not much, there being 16 or 18 oxen to each load--each column of baggage alone is 15 miles long, but to this distance must be added 5 yards interval, and this gives 18 miles to defend. Of course, the forage for the large cavalry force made one of the greatest strains upon the commissariat, and all had to be sacrificed to this necessity. This column and Crealock's were in this respect not upon a par, as it had to provide for not less than 2000 horses, each receiving 12 lb. of corn daily; which gave a total of 24,000 lb. daily, or 3000 lb. per waggon load, or 6 waggons daily to supply them. At this rate, therefore, it required 120 waggons to carry the oats for the cavalry alone. All Lord Chelmsford's and the staff horses were, however, placed upon half rations. Ibabanango, which Lord Chelmsford had selected as an advanced depôt for the united forces of his column and that of Wood, is again situated about midway between this place (Kopje Allein) and the king's kraal at Ulundi. The troops in this camp consisted of a company of Engineers, the cavalry brigade, two batteries of Royal Artillery, four line battalions, and 800 natives. The encampment was rather extensive, but this upon sanitary grounds and the best medical advice. The battalions were encamped as at open order, front as in line, with a depth of 116 yards, which is unusual, for half the above frontage is the usual encampment, and 30 yards were left between each of the four battalions. Each regiment of cavalry usually occupies 172 yards of front and 130 yards of depth, but its camp can be condensed to 120 yards of front by crossing heel-ropes, and this, for defensive reasons, was the plan adopted by General Marshall. This could not be done with Cape or Indian remounts, as entire horses would fight if so close to each other; but English horses are so accustomed to this proximity that it was found they throve better when allowed companionship. To each battery of artillery was allowed a frontage of 133 yards, with a depth of 114 yards, or 70 yards front at close order, while from centre to centre of the tents 10 paces were allotted. The kitchens were simple enough, being nothing more than a trench to catch the wind and hold the usual pattern of Flanders or Torrens kettle--the former, weighing 8-1/2 lbs., holding twelve quarts,
