[Footnote 101: The northern road had been reconnoitred and found to be without water.] [Sidenote: Night march Oct. 25th-26th.] At 6 p.m. began a night march of great distress and trouble. Soon after the advance guard moved off, a heavy downpour converted the road into a sea of semi-liquid mire, which the transport ploughed into waves and furrows. These, invisible in the black darkness, almost held down the soldiers plunging knee-deep into them. The teams of mules, exhausted by prolonged labour and insufficient food, impatient by nature of wet and darkness, strove with much suffering to drag the rocking wagons through the mud, and, as is their habit when overmastered by their load, threw themselves often in confusion athwart the track and enforced a halt. At 9 p.m. the whole of the transport stuck fast for more than two hours. The rearguard closed up, but the troops in front of the baggage, knowing nothing of its misfortunes, and travelling on a road not destroyed by its struggles, pushed on and left it. With great efforts it was set in motion again, but some half-dozen of the wagons, being imbedded hopelessly, had to be abandoned.[102] Half a mile further the convoy was again in difficulties. From this point all cohesion was lost. Some of the wagons passed on, some remained; it was impossible for their escorts to tell which were derelict and which they must still consider as in their charge. [Footnote 102: They were recovered next day.] [Sidenote: Coxhead's relief column.] Throughout the night Lieut.-Col. Coxhead, R.A., who had left Ladysmith at 9 a.m. on October 25th, lay waiting about a mile east of the Nek between Bulwana[103] and Lombards Kop for the Dundee column to join hands with his own. With him were the 5th Lancers, half a battalion 2nd Gordon Highlanders, half a battalion 1st Manchester regiment, the 21st battery R.F.A., and a convoy containing two days' supplies, which General Yule had asked for, in a message despatched from the bivouac at the Waschbank river on the 24th. Coxhead immediately gained touch with Yule by means of his mounted troops, and learning that the food would not be required, sent the wagons back. All day the troops from Ladysmith remained on the Helpmakaar road. But night and torrents of rain fell together, and Coxhead's men bivouacked in discomfort only less than that of their comrades toiling towards them, still nine miles distant.
