The loss of the enemy, though shrouded as usual in darkness, was certainly very much higher.
On October 31st the Boers ventured upon an attack on Cannon Kopje, which is a small fort and eminence to the south of the town.

It was defended by Colonel Walford, of the British South African Police, with fifty-seven of his men and three small guns.

The attack was repelled with heavy loss to the Boers.

The British casualties were six killed and five wounded.
Their experience in this attack seems to have determined the Boers to make no further expensive attempts to rush the town, and for some weeks the siege degenerated into a blockade.

Cronje had been recalled for more important work, and Commandant Snyman had taken over the uncompleted task.
