Meanwhile the apparently endless line of waggons had been blocked by a bad drift below the camp, and the brigade was called upon to help. The road was somewhat improved by throwing into the soft mud stones obtained from a wall, and many waggons had to be hauled by ropes through the spruit. For over forty-eight hours did that collection of vehicles continue to cross and require help.
On Thursday, January 12th, the 4th Brigade and General Warren's Division passed through the camp and went straight on to Springfield, since the cavalry had ascertained that there were no Boers south of the Tugela in that direction. The 5th Brigade followed on the afternoon of the 15th, crossing the Little Tugela by a foot trestle-bridge made of spars cut by the Engineers from trees on the bank. As the battalion approached Springfield, the sound of artillery-fire greeted it, and our shrapnel could be seen bursting against a hill which was evidently on the left bank of the Tugela. It was clear that the army was again in touch with the enemy, but nobody knew what Sir Redvers Buller had decided upon, although everybody, of course, dogmatised on what he ought to do.
On the afternoon of the 16th, orders were issued for the brigade to march that night, although nothing was stated regarding its destination. Vigorous operations were plainly intended, since the force was to move as lightly as possible. No tents or blankets were allowed, and the great-coats were carried by the regimental transport, in which officers were permitted to pack twenty pounds of baggage. Six days' rations were also taken.
The army moved from Springfield at dusk, leaving the camp standing in charge of a few details (cooks, &c.), who had strict orders to light fires and walk about, so that the vigilant burgher might not discover that the army had slipped away. The general direction of the march was north-west. It was a bright moonlight night, but the column moved slowly, for the numerous waggons took up the centre of the road, while the troops moved on the side. About midnight it began to rain, which made everybody cold and uncomfortable, especially as halts were long and frequent. It was not easy to see where the army was going, although the Tugela could not be far off. Nobody knew the plan of operations, which, however, evidently aimed at a surprise crossing of the river, and it seemed as if the enemy must hear the noise of the creaking transport and tramping men.
About 2 a.m. there came a halt on the top of a ridge, where General Hart formed up his brigade. Each regiment deployed into line, and then lay down one behind the other in the following order: Royal Inniskilling Fusiliers, Connaught Rangers, Royal Dublin Fusiliers, and Border Regiment. Fatigued by a long night-march, every one soon fell asleep. Unfortunately, however, the slumbers of the brigade were disturbed by an incident which shows how easily confusion can arise in night operations. A horse from somewhere in front broke loose and galloped over the veld, straight into the ranks of the sleeping regiments. For a moment everything was in confusion, and a general panic nearly took place. Luckily the first glimmer of dawn had come, and the company officers soon regained control of their men, but it might have been a different tale had darkness still prevailed.
When daylight came, it showed the army to be on the top of a hill overlooking Trichardt's Drift. On the other side of the river the ground rose to a long ridge flanked on the east by a steep mountain, and on the west by a bastion-like hill. Nobody then knew the country, but that mountain was Spion Kop, and the ridge lying so calmly in the morning light was to be the scene of six days' continuous fighting. At dawn of January 17th, however, the ridge, which the natives called Tabanyama, seemed deserted, and not a Boer was to be seen.
It was now learnt that Sir Redvers Buller had divided his forces, sending two brigades, under General Lyttelton, to Potgieter's Drift, while the remainder of the army, under General Warren, was assembled ready to cross the river at Trichardt's Drift.
The battalion breakfasted quietly, and then 'H' company was sent down to the drift in order to help in the construction of a bridge. As the company descended the steep slope, the artillery from the heights began to shell a farm on the far side of the river, whence a Boer patrol had been sniping. The Engineers had massed the pontoon waggons round a farm by the drift, and were looking for a suitable point for the bridge. The pontoons were launched, and by 11.30 a.m. the first bridge was ready. The infantry immediately began to cross, but the artillery and transport had to wait for a second bridge, which was not completed until after dark.
The 5th Brigade marched down to the river at 2 p.m. and crossed. On reaching the left bank the battalion deployed into line, with four or five paces between the men, and slowly moved up the slope in support of the widely-extended lines of the Lancashire Brigade. Except for an occasional shot from the artillery at Potgieter's Drift, everything was still and peaceful; although, as the army moved away from the river, most of the officers expected to be greeted by the familiar 'pick-pock' of the enemy's mausers.
The brigade in front eventually halted on the top of a minor ridge, some three thousand yards or more from the crest-line of Tabanyama, and separated from it by open and gently-sloping ground. The Dublin Fusiliers formed quarter-column immediately behind the Lancashire Brigade, and prepared to bivouac. Many of the officers strolled higher up in order to look at the country through their glasses. The main crest-line was evidently occupied, for men could be seen busily digging. It was somewhat trying to think that precious time was being wasted, while the burghers were preparing a defensive position.
