On the following day the Boers were only 10 miles off; but the horses of the column were too done to move until the evening. At Liebenbergspan a number of mules and horses, taken with Hamilton's transport, were recovered. It was necessary now to draw fresh supplies; Col. du Moulin accordingly went to Jagersfontein on the 22nd and drew supplies from Vlakfontein. Over 10,000 rounds of mixed ammunition were destroyed, which had been found in the town, sunk in a flooded mine.
The Boers (three commandos under Nieuwoudt) had turned north, and the column started after them on the 23rd. The Riet River was crossed at Jagersfontein Drift on the 24th, and Witdam was reached on the 26th. On the following day Col. du Moulin got again into touch with the Boers. The column had started at 5 a.m., and, while it was halted for breakfast, four men were seen by Capt. Beale, the Intelligence Officer, leaving a farm some miles off. Capt. Griffin was sent out with his company to reconnoitre, and came upon the spoor of a large party. Mounting a high kopje, he saw the four join a large laager of some 400 Boers, with spare horses, cattle and three Cape carts, which was on the move. The column followed, passed through the Boers' camp at De Dam, and by the evening arrived at a drift over the Riet River. This drift lay under the farm of Abraham's Kraal, and here the column bivouacked. The Boers, expecting them to take a different route, had crossed the River a few miles lower down, and were waiting on the further bank.
At Abraham's Kraal, the farm houses are at the open end of a semi-circle some 200 yards in diameter, formed by a low ridge that rises here and there into small kopjes covered with large stones. Beyond the buildings and facing the semi-circle is a garden with a stone wall. Standing with one's back to the garden and buildings, on the right is a large stone kraal, divided into several compartments. In front is the highest part of the ridge, beyond which the ground drops very quickly to the Riet River. On the left, the ridge ends in a conical rocky mound, with a small kraal at its foot. On the outside of this mound a donga leads up from the river, and curls in towards the farm.
The horse lines were placed across the semi-circle, parallel to the garden wall. On the river side of them, the officers' valises were laid out. The Colonel and his staff slept in the farm house, which was at the end of the ridge near the largest Kraal. The pom-pom was at the foot of the conical mound, on the road that here entered the semi-circle. The transport was along the garden wall, to the right rear of the horse lines.
Three piquets were put out, one of them on the highest part of the ridge, looking towards the river and drift. It will be convenient to call this the camp piquet. The river could not be actually seen from this piquet, owing to the rapid drop of the ground. The two other piquets were placed upon small kopjes, one to the right of the camp piquet outside the semi-circle, and one in rear of the garden. The men in camp, done up with many days of continuous trekking, turned in.
At about 1 a.m. a Sergeant got up to put the nose-bag on his horse, as a patrol was to go across the river at 3. As he was walking back to his place, he heard a shot fired on the piquet, and shouted "Stand to!" Almost immediately a tremendous fire was opened upon the centre of the camp. The men woke to hear shouts and yells of "Come on you Bob-a-days"—"Vorwatz Burghers"—and to see through the misty moonlight (for the night was cloudy) swarms of dark figures topping the crest of the piquet within 200 yards of them, and rushing down the slope, firing from their hips. Nieuwoudt, after being chased so far by the column, was striking back at last.
The Boers had been forced into action. Col. Western with his column was closing in upon them from the west, Major Driscoll was coming up from the south. If they were to avoid facing a combination of columns, it was necessary to attack one of them at once. Col. du Moulin was close on their heels, and his force was numerically inferior.[24]
Nieuwoudt therefore planned this night attack, entrusting the execution of it to Commandant Theunissen.
The attacking Boers had crossed a drift, worked up the river bed (out of sight) till they were below the camp piquet, crept up the steep hillside, and then rushed the sentry and piquet, killing two men and having two men killed—one of them the owner of the farm. They then started firing down into the camp, while some rushed across the saddle to their left and occupied a large kraal, and others began to work along the ridge to their right. One or two ran straight down the slope.
