The involvement of men from the Australian colonies in the Second Boer War was complex. They included the official contingents dispatched by each of the six colonial governments, Australians who were already in southern Africa working as gold-miners enlisting in British or Cape Colony regiments such as the
Bushveldt Carbineers, men who made their own way to participate, and others who joined privately raised units such as Doyle's Australian Scouts. After Australia federated to become the Commonwealth of Australia, the men of the six separate colonial contingents were reorganised into new Commonwealth contingents. The Australian contribution consisted of five phases. The first was the contingents each government dispatched in response to the outbreak of the war. Although hostilities only commenced on 10 October 1899, the first squadron of New South Wales Lancers arrived in
Cape Town on 2 November to join the British force assembled under the command of
General Sir Redvers Henry Buller. The Lancers had been training in England at the time, and were quickly dispatched to southern Africa as soon as permission was received from the
Government of New South Wales. By 22 November the Lancers were already conducting patrols, and were soon attacked near
Belmont, where they forced their attackers to withdraw after inflicting serious casualties upon them. The NSW Lancers were again called into action at the
Battle of Modder River, where along with
Lord Methuen's British column, they attempted to relieve the siege of Kimberley. Although they forced the Boers to retreat, the British suffered heavy casualties in the attempt, and also had to withdraw, allowing the Boers to re-establish their trench lines. As they had less distance to travel, the Western Australian contingent, consisting solely of the 1st Western Australian Mounted Infantry arrived in mid-November, were the first to arrive directly from Australia, and were quickly dispatched for Natal. On 26 November, the first contingents of infantry from South Australia (1st
South Australian Mounted Rifles), Tasmania (Tasmanian Mounted Infantry), Victoria (1st Victorian Mounted Rifles) and Western Australia arrived in Cape Town, and despite retaining their own independent commands, for logistical reasons they were designated as the '1st
Australian Regiment', and came under overall command of Major-General Sir
John Charles Hoad. The 1st Queensland Mounted Infantry had also arrived to join them by mid-December. Another mounted infantry unit from New South Wales, known as the
1st Australian Horse, also arrived in December. Despite their name, they were raised purely from within the Colony of New South Wales, although this unit would go on to become the precursor of the first
Australian Light Horse unit. Hoad ordered the combined force to ride north towards the
Orange River, where they were to link up with the Kimberley Relief Force under
Lieutenant-General Lord Methuen. Although they were in the Cape Colony at the time, no units from the Australian colonies were involved in the
Black Week between 10 and 17 December, in which Britain suffered three successive defeats at the
Battle of Stormberg, the
Battle of Magersfontein, and the
Battle of Colenso. The Boers knew that Empire forces would be sent to reinforce the British positions, and so sought to strike quickly against them. By mid-December, the first two contingents of New South Wales Mounted Rifles (A Squadron and E Squadron), and the first contingent of Queensland Mounted Infantry (1st Queensland Mounted infantry) had both also arrived directly from Australia. ==Aboriginal soldiers==
