The Yeomanry did a lot of useful work, and are as eager for fight as a bull ant on a hot plate. They are as good as any men I have seen in Africa, full of ginger, good horsemen, wear-and-tear, cut-and-come-again sort of men. They adapt themselves to circumstances readily, are jolly and good-humoured under trying circumstances. Their officers are, as a rule, first-class soldiers, equal to any emergency. On Tuesday the Boers kept their guns going at a great rate, and we really thought that they had made up their minds to see the thing right out at all costs. Personally I did not for a moment think that they were ignorant of General French's rapid advance. I do not believe it possible for any large body of hostile troops to move in South Africa without the Boers being thoroughly cognisant of every detail connected with the move, partly because they are the most perfect scouts in the world, and partly because the scattered population on every hand is positively favourable to them. Our artillery dropped a storm of shells during the day, and that night it was whispered in camp that there was to be a general attack next morning. On Tuesday evening General French advanced right on to the Boer rear, and some smart fighting took place, the enemy suffering considerably, though our losses were small. At dawn on Wednesday we moved forward rapidly, and in a few hours' time our infantry were standing in the trenches and upon the hills that the Boers had occupied the day before. Our mounted men rode at a gallop through the gullies, but nothing was to be seen of the foe except a few newly dug graves. The Boers had vanished like a dream, taking all their guns with them. Louis Botha, the commander-in-chief, had come in person to them, and the retreat was carried out under his eyes. We followed to Dewetsdorp, and from there on to Thaba Nchu (pronounced Tabancha). On Friday night the enemy exchanged a few shots with us from the heights beyond, but no harm was done on either side. The Third Division, to which I had attached myself, under General Chermside, has been ordered towards Bloemfontein. French is in command, and, judging by his past performances, I fully expect we shall have some busy times, though French may go away and leave the Eighth Division under General Rundle.
