Hussar Hill was again taken, and from that day the operations, though varying in activity, were continuous until the 18th, when, after two days of heavy fighting from hill to hill, the British succeeded in gaining possession of Green Hill, their ultimate object, upon the enemy's left flank.

The Boers then evacuated Hlangwane, which was occupied on the 19th by the British.

The positions of the Boers south of the Tugela and east of the bend had {p.295} thus all fallen, weakening their left flank, at the same moment that Roberts, arriving at Paardeberg, found Cronje hemmed in the bed of the Modder.
Buller's turning movement had now driven the Boers into the mountainous country between Colenso and Ladysmith, west of the bend in the Tugela.

Here, when his campaign opened in December, had been the strength of their position.

Its general character has been already mentioned, as well as some particular features--Grobler's Kloof, two miles above Colenso, the kopjes behind Fort Wylie commanding the bridge, etc.
