During the campaign by General Smuts in the Cape Colony his Commando laid siege to the mining town of O’okiep, a small copper mining town in the Cape Colony that eventually became the headquarters of the Cape Copper Mining Company. The neighbouring towns of Concordia and Springbok had surrendered. On 4 April 1902, Smuts demanded the surrender of O’okiep. The soldiers stationed at O’okiep were made up of the fifth Royal Warwickshire’s and a number of Namaqualand Town Guard Battalion members, consisting of a sizeable number of Black and European miners. The defence was conducted by Lt.-Col. W.A.D. Shelton, DSO, and Maj. J.L Dean of the Namaqualand Town Guard, the Company’s manager. Colonel Shelton, the Commander of the British garrison at O’okiep, refused to surrender and on 4 May 1902, a relief column arrived from Port Nolloth and ended the siege.
340 Private A. Fritz is confirmed on the roll of the Namaqualand Town Guard as having been engaged with the enemy at O’okiep when the mining town was besieged.
The garrison consisted of 206 European miners, 660 Cape Coloureds, 44 men of the 5th Warwickshire militia and twelve men of the Cape Garrison Artillery.
