After the death of Joubert the control of the Boer forces fell into the hands of younger men, the most conspicuous amongst whom was Christian de Wet. Having conceived a plan for capturing the Waterworks guard, he placed his forces astride of the road, and hid them in the bed of a stream about five miles west of the Modder River. When the day arrived for the execution of his plan, he found that the mounted column was also delivered into his hand.

Sannah's Post

A messenger got through who carried news of Broadwood's plight between Olivier and De Wet to Lord Roberts, and he sent out an infantry division under General Colvile. But the two forces failed to work together, and the enemy triumphed. This was on Saturday, March 31.

"The material result of De Wet's achievements at Sannah's Post was the acquisition of seven guns, much ammunition, many horses and waggons, and a large number of prisoners. By occupying the Waterworks, which did not again pass into Lord Roberts's hands until April 23, he inflicted great injury on the health of the troops in Bloemfontein. The moral effect of his success was enormous. It confirmed the resolution of those of the Free State burghers who still remained in arms; it encouraged the waverers; it afforded De Wet the occasion for putting strong pressure upon the considerable numbers of his fellow countrymen who, declaring themselves tired of the war, had given in their rifles to the British troops, and had been allowed to return to their farms as peaceful non-combatants; and it gave those who followed him good heart for his next stroke."[[17]]

On the Sunday following Gatacre was summoned to Headquarters, and had interviews with the Commander-in-Chief, of which he has left the following memorandum:

"On Sunday, April 1, I proceeded to Bloemfontein by order to see Lord Roberts, arriving late at night. Early next morning (April 2) I saw the Field-Marshal, and he told me he was placing me in command of the Orange Free State territory held by us, and was giving me ten other battalions, which were to be used as under, i.e. six Militia battalions to be distributed along the railway south of Bloemfontein, and in the country east and west of it; the four battalions were, with the four I had already (the 2nd wing of the Berkshire was to be called up from Cape Colony), to make up a Division with which I was to proceed at once to Dewetsdorp and operate along the Basuto border through Ladybrand, Clocolan, Ficksburg country, to clear Lord Roberts's right flank, to enable him to advance northwards. He directed me to draw up for his approval a scheme of distribution for the six Militia battalions through the country. This I did, and submitted it on the spot. The Field-Marshal was anxious to know by what date I considered I could concentrate my troops at Reddersburg, ready to move, after relief by the Militia battalions. I replied that, on the assumption that I received the Militia battalions on the 6th, I could move on April 17 (reliefs had to be effected, transport collected, supplies, etc., etc.). This date was considered satisfactory by Lord Roberts. The same evening (April 2) about 9.30 p.m. Lord Roberts again explained to me carefully what he wished, that he was anxious for me to move as soon as possible, and that I was to proceed to Springfontein immediately, and commence preparations. This I did, morning of April 3, by first train."

It would appear that nothing was said during the Monday spent at Bloemfontein about the detachment that was moving that very day from Dewetsdorp through Reddersburg back to the railway at Bethanie. No anxiety seems to have been felt at Headquarters as to what De Wet would do next.

A relief column

At about 7 o'clock on Tuesday evening, April 3, information was brought into Edenburg that the Dewetsdorp detachment was surrounded at Mostert's Hoek, a ridge three or four miles east of Reddersburg. This disquieting news was telegraphed to Lord Roberts, who sent an urgent message to Gatacre directing him to prepare to move on Reddersburg, and asking what troops he had available. The reply stated that there were forty scouts and about twenty-five mounted infantry at Springfontein, a Brigade Division Field Artillery at Bethanie, and about two companies mounted infantry at or near Edenburg. A return message informed Gatacre that the Field-Marshal was sending five companies of the Cameron Highlanders by train to Bethanie, and told the General that he was on no account to go without them.
