7 June 1900
During the South African War 1899-1902, General Christiaan de Wet attacked Rooiwal railway station at Koppies, Northern Free State. At this point he was the commando-in-chief of the greater part of the Free State commandos. A day before the assault De Wet, his men and burghers, set off from Smitsdrif. Following a few gun shots, General De Wet sent a burgher with a flag of truce to the British commander. His message read that the station was surrounded by 1 000 men with four guns and he called upon the post to surrender within ten minutes. The British commander Captain A. G. W. Grant sent back the burgher with the message saying that he would certainly not surrender. De Wet then ordered his commandos to fire at the British and they in turn returned fire.
