The Boers had earlier met at the temporary new capital of the Orange Free State, Kroonstad, and planned a guerrilla campaign to hit the British supply and communication lines.

The first engagement of this new form of warfare is at Sanna's Post on March 3, where fifteen hundred Boers under the command of Christiaan de Wet attacks Bloemfontein's waterworks about thirty-seven kilometers (twenty-three miles) east of the city, and ambush a heavily escorted convoy, which causes one hundred and fifty-five British casualties and the capture of seven guns, one hundred and seventeen wagons, and four hundred and twenty-eight British troops.
