With intelligence that de Wet was in the vicinity of Elandskop, the British line was formed along the Liebenberg’s Vlei River in a line ninety kilometres long. The sweep to the west as far as the main railway line was detected by de Wet’s scouts and he moved south with his force of seven hundred men who had joined him at Slangfontein. Managing to avoid the advancing British line they crossed the Kroonstad-Lindley blockhouse line on the farm Doornkloof on the night of 6^th February heading for the Doornberg, north west of Senekal. The British swept on westwards and closed off the area between America Siding on the main line and Heilbron on the night of 7^th February. Numbers of Boers were known to be within the cordon and every possible means was used to ensure their capture. Nearly three hundred were killed, wounded or captured.
