On the evening of November 11, 1914 General
Louis Botha gathered a large
cavalry and
motorized infantry force along with two artillery batteries of the
Cape Field Artillery and left Winburg with the
Transvaal commando of the
Union Defence Force proceeding in the direction of
Marquard in order to surround de Wet. de Wet was reported by British sources to be in a spot known as Mushroom Valley slightly northeast of Bloemfontein and southwest of Winburg. Colonel Brand, with another strong force, moved out from Winburg to Hoenderkop, and came up with a section rebels under Hendrik Serfontein, Brand's Union Defense Force commando consisted of roughly 1,300 men. Botha's cordon was completed by General
Henry Lukin who had recently been attacking Germans in
German West Africa during the
West African Campaign, alongside Colonel Coen Brits who had recently skirmished with
Manie Maritz. Botha's plan was to drive de Wet's forces into a
quarry close to Mushroom Valley an push de Wet's forces directly into Lukin and Brits and hopefully get de Wet to surrender. One noted failure on de Wet's part was the fact that he did not have his men cut the
telephone line from Mushroom Valley to Winburg, making it easy for loyalist Afrikaners to inform Botha of De Wet's exact location. De Wet also failed to post centuries outside of his
laager. Many of Botha's troops were transported to the area by cars which were made available by the Transvaal Automobile Club among others, two of the cars were equipped with machine guns. It is citied by several sources that Botha's use of armored cars played a vital part in De Wet's defeat. == Battle ==
