In the reorganisation that followed, the Queensland Mounted Infantry became part of Major General Edward Hutton's 1st Mounted Infantry Brigade, along with the Canadian and New Zealand mounted units. Chauvel distinguished himself fighting alongside a group of New Zealanders and capturing a Maxim gun. The Queensland Mounted Infantry participated in the capture of Pretoria and the Battle of Diamond Hill. Chauvel was given a mixed force of British, Australian, Canadian and New Zealand mounted troops that became known as "Chauvel's Mounted Infantry", with Victor Sellheim as his chief of staff. Initially, Chauvel was given the mission of escorting 10,000 head of cattle to Belfast, Mpumalanga to supply the troops in the eastern Transvaal. However, his force was diverted by local commanders, who assigned it to burning homesteads sheltering Boer commandos and attacking Boer units. The Queensland Mounted Infantry embarked for Australia on 13 December 1900. They reached Brisbane on 17 January 1901 and the regiment was disbanded there on 23 January. For his part in the fighting, Chauvel was mentioned in despatches, and appointed a Companion of the Order of St Michael and St George (CMG).
