Below Fort Wylie the river continued south-easterly for something less than a mile. Then with a bold sweep it curves north, and round west, to a point half a mile north-east of the fort, when it again flows due north for a couple of miles. From this formation results a tongue of land, embraced in the curve, projecting to the south-east, and much resembling a bastion, to which the subsequent northern stretch serves as a curtain. In general effect, however, the river may be broadly said to make below Wylie a sharp turn to the north, running that way for two or three miles, after which it resumes its general easterly course towards the sea. The point where it thus resumes its direction is well to the north--rear--of the line of Boer entrenchments, between Grobler's and Wylie, so that, if their positions were prolonged on that {p.223} same line, they would be separated by the river. If, on the other hand, instead of so continuing, the entrenched works were made to follow the river course north, keeping always on the same side of the Tugela, the main Boer positions, confronting the bridge, would be open to enfilading fire from the eastern hills on the opposite side below the bend. Such conditions would seem to make this eastern part of the Boers' position--their left flank--the weakest. The outcome of the campaign tends to confirm this conclusion, which the author has been interested to find also in a letter, not only composed, but published, before the abortive attempt to turn the west flank at Spion Kop. "To the east of Fort Wylie," wrote a correspondent of the London _Times_ on December 21, "the Tugela bends sharply northward, and here the left flank of the Boer position is on the south sides of the river, on a solitary hill called Hlangwane. This is doubtless the weakest spot in the Boer position, for if an enemy could take it by storm or otherwise, he could render the kopjes north of Colenso untenable."[27] {p.224} This shows that the Boers preferred to have their lines divided by a river fordable only in places, and at times impassable through floods, rather than leave their flank uncovered to artillery, a decision probably correct. As shown by the plans, Hlangwane, as an eminence, stood by itself; a mile and a half to its east and rear was another height named Monte Cristo, and again to the westward a range called Inhlawe Mountain. [Footnote 27: London _Weekly Times_, January 19, 1900. On the other hand, another correspondent who shared this view has said, "The consensus of military opinion seems to be that the ground being too rough and broken to the eastward, the chief column will try and effect a crossing far to the westward of Colenso." (Burleigh--p. 155).]
