Joined Lord Methuen before Magersfontein was fought, 11th December 1899 (see 2nd Black Watch). Lord Methuen said in his despatch, para 33, "G Battery RHA fired hard till dark, expending nearly 200 rounds per gun". The number actually fired was 1250 for the six guns, being the largest expenditure on record (see the evidence of Major General G H Marshall before the War Commission, p 361). Major Bannatyne-Allason was mentioned by Lord Methuen. Unofficial accounts very highly praised the handling of the battery. They had 2 officers and 3 men wounded. The battery took part in the rush to Kimberley. G and P were the two batteries which accompanied Broadwood in the hurried ride from Kimberley on 17th February 1900, and had the honour of heading Cronje at Koodoesrand Drift, one of the most successful and striking incidents in the campaign. They took part in all the subsequent fighting on the way to Bloemfontein, and afterwards on the way to Pretoria and at Diamond Hill. Two guns of G were with General Alderson's column in the Eastern Transvaal in January and February 1901. The battery was brought to Cape Colony in February 1901 to pursue De Wet (Lord Kitchener's despatch of 8th March 1901). Afterwards four guns were with Colonel Bethune in the Orange River Colony (despatch of 8th July).
