Throughout 1900 his successes mounted – Sanna’s Post, Mostert’s Hoek but a reverse at Wepener. There the British force, mostly Colonial troops, put up a stout defence. De Wet’s attacks continued and on ^7th June 1900 his commando succeeded in overwhelming a small British force at Roodewal Station. The Boers captured a huge quantity of stores said to value anything up to £250 000. (De Wet in his book “Three Years’ War” said £750 000!) What they could not carry away was burnt, including the army mail. Communications between Pretoria and Kroonstad were cut and the rail line for several miles was completely broken up.
