The surrender of Cronje had taken place on February 27th, obliterating for ever the triumphant memories which the Boers had for twenty years associated with that date. A halt was necessary to provide food for the hungry troops, and above all to enable the cavalry horses to pick up. The supply of forage had been most inadequate, and the beasts had not yet learned to find a living from the dry withered herbage of the veld. [Footnote: A battery which turned out its horses to graze found that the puzzled creatures simply galloped about the plain, and could only be reassembled by blowing the call which they associated with feeding, when they rushed back and waited in lines for their nosebags to be put on.] In addition to this, they had been worked most desperately during the fortnight which had elapsed. Lord Roberts waited therefore at Osfontein, which is a farmhouse close to Paardeberg, until his cavalry were fit for an advance. On March 6th he began his march for Bloemfontein. The force which had been hovering to the south and east of him during the Paardeberg operations had meanwhile been reinforced from Colesberg and from Ladysmith until it had attained considerable proportions. This army, under the leadership of De Wet, had taken up a strong position a few miles to the east, covering a considerable range of kopjes. On March 3rd a reconnaissance was made of it, in which some of our guns were engaged; but it was not until three days later that the army advanced with the intention of turning or forcing it. In the meantime reinforcements had been arriving in the British camp, derived partly from the regiments which had been employed at other points during these operations, and partly from newcomers from the outer Empire. The Guards came up from Klip Drift, the City Imperial Volunteers, the Australian Mounted Infantry, the Burmese Mounted Infantry and a detachment of light horse from Ceylon helped to form this strange invading army which was drawn from five continents and yet had no alien in its ranks. The position which the enemy had taken up at Poplars Grove (so called from a group of poplars round a farmhouse in the centre of their position) extended across the Modder River and was buttressed on either side by well-marked hills, with intermittent kopjes between. With guns, trenches, rifle pits, and barbed wire a bull-headed general might have found it another Magersfontein. But it is only just to Lord Roberts's predecessors in command to say that it is easy to do things with three cavalry brigades which it is difficult to do with two regiments. The ultimate blame does not rest with the man who failed with the two regiments, but with those who gave him inadequate means for the work which he had to do. And in this estimate of means our military authorities, our politicians, and our public were all in the first instance equally mistaken.
