While the majority of the Natal Naval Volunteers were demobilised at Durban in April 1900, two Officers and 21 men went back to the front and were again attached to Buller's Force. With the latter they crossed the Buffalo River into Transvaal at the end of May and took part in the actions of Laing's Nek and Pieter's Hill. This small group was eventually disbanded at Durban at the end of June, having earned the fulsome praise of Captain Jones, R.N.:

'The Natal Naval volunteers have had very arduous work, especially during the last six weeks, and were in all the fighting there has been with General Buller's Force. Their conduct has been on all occasions irreproachable, and their services invaluable. I shall always be proud of having commanded such an active body of men, and grateful of their loyalty and ever willing services' (Natal Volunteer Record refers).
In 1904 their title was changed to the Natal Naval Corps and 150 men served in the 1906 Bambata Rebellion, partly as Field Artillery and partly as Infantry.
