I gave Commandant Jacobsz orders to come to me with his fifty men on Christmas Eve, but this time with the strict injunction that he must conceal his march from the enemy. I also called up Veldtcornet Beukes, with his fifty men, from Wilge River, in the district of Harrismith. Veldtcornet Beukes was a brave man and trustworthy; he was shortly afterwards promoted to the command of a division of the Harrismith burghers.

My intention was to attack Colonel Firman early on Christmas morning.

Two days previously I had, with General Prinsloo and the Commandant, reconnoitred the neighbourhood of Groenkop, on which Colonel Firman was encamped. I approached as near as possible to the mountain, but could only inspect it from the west, north, and east, but on the following day I reconnoitred it also from the south.

My plan of making the attack early the next morning was somewhat spoilt by the fact that the English had already, on the 21st of December, quitted their camp on the mountain. Thus they had had four days in which to entrench themselves.

Whilst we were reconnoitring the mountain from the south, we saw three horsemen coming cautiously out of the camp, riding in a north-easterly direction, and thus giving us no chance to intercept them. Commandant Olivier and Captain Potgieter now made a détour, so that they could cut off the unsuspecting scouts from their camp, and could also get nearer to the mountain themselves. I knew that by doing so they would draw the fire of the two guns, which would tell me precisely where Colonel Firman's battery stood.

Before these officers could accomplish their purpose they were observed, and seeing that they could not cut off the three men, they turned their horses and galloped back. But when they saw that the three scouts had the temerity to pursue them, they faced round at the first rise and suddenly confronted them. The three (who were Kaffirs), seeing that the tables were turned, hastily wheeled round towards their own camp, but before they could reach it one of their number was caught and shot down. One gun and the Maxim-Nordenfeldt now fired upon our two officers as long as they were in sight, and thus we learnt that the guns were placed on the high western point of the mountain, from which they could shoot in all directions.

Let me describe Groenkop. On its western side was a precipice, on the north and south a steep descent, and on the east a gentle slope which ran down to the plain.

From which side should the attack take place?

Some of the officers were of the opinion that this should take place on the east, where it was the least steep, but I differed from them, for through our field-glasses we could see that the walls of the fort were so built that it was quite clear the enemy had thought that, should they be attacked, it would be from the east. The forts were built in a semicircle towards that side, and although this would be of little importance once the fight had begun (because the defenders had only to jump over the wall to find themselves still entrenched), still it was to the advantage of the attacking party to come from a side where they would not be expected.

These reasons brought me to the conclusion that the English would not be on the look-out for us from the west, and I therefore decided to make the attack from this side, the steep side of the mountain. But I did not then know how steep it really was.
