The conditions leading to the choice of this point appear to have been as follows. Eastward of the north and south stretch just specified, and as far as to the Ladysmith railroad, the mountain ranges north of the river are not only high, but wide, broken, and intricate, ending in Grobler's Kloof and the other kopjes mentioned in describing the positions at Colenso. The reverse slopes of this broken region are full six miles north of the river's course. The map shows the district almost wholly bare of roads, an indication that it is unsuited to large military operations. Upstream of the stretch, the ranges, though steep and broken, are very much narrower. Three miles west of it, at Potgieter's Drift, a road passes through from Springfield to the plain beyond at Brakfontein, showing a considerable depression at this point. By this road was made the second unsuccessful attempt of the campaign, towards Vaal Krantz. Four miles higher up, at Trichardt's Drift the {p.252} chain leaves the river, trending north-north-west for eight miles, with a breadth which, beginning with three miles at the south, narrows to one and a half, with lessening elevation, towards the north end, where it drops to the plain. The western slope of this eight mile spur, over the southern part of which, contrary to first intention, the British attack was actually made, is precipitous near the summit; lower down it is more gradual, but still steep. A mile from the foot of the spur, and parallel to it, runs a stream called Venter's Spruit, which enters the Tugela from the north-west a little above Trichardt's. Six miles from the ford, between spur and spruit, is Acton Homes, the point designated by Buller as the first objective of the army, whence the range was to be crossed. The change of direction noted at Trichardt's gives to the whole range, from Colenso to Acton Homes, the character of an arc of a circle, on the interior of which, considered as a defensive position, the Boers moved, with the additional advantage of being all mounted men. Near the southern end of the spur, but well to its eastern edge, is the lofty eminence called {p.253} Spion Kop, which played so important a part in the operation as it ultimately developed. At Acton Homes roads meet from north, south, east and west; a fact which sufficiently indicates the importance of the point and the comparatively favourable nature of the surroundings for operations--for roads usually seek the easiest ground. From it two start east for Ladysmith, crossing the spur by different ways, and uniting some eight miles beyond in the plain lying west of Ladysmith, where the network of communications shows the relatively open character of the country. It was by one or both of these roads that Buller purposed to advance.
