"C" Battery arrived at Cape Town aboard the SS "Columbian" in March 1900, but within two weeks were re-embarked to sail to Beira, from where they travelled by train, cart, and forced march to join Lieutenant-Colonel Herbert Plumer's column south of Otse by mid-April to take part in the relief of Mafeking. Colonel Baden-Powell, the garrison commander at Mafeking, sent a telegram to the Canadian Government stating : "Mafeking relieved today, and most grateful for invaluable assistance of Canadian Artillery, which made record march from Beira to help us". From the end of May the battery operated with Plumer's column in the Zeerust district until November, seeing action regularly.
