Boer War

The origins of the Boer War lay in Britain's desire to unite the British South African territories of Cape Colony and Natal with the Boer republics of the Orange Free State and the South African Republic (also known as the Transvaal).

The Boers, Afrikaans-speaking farmers, wanted to maintain their independence. Indeed, in 1880-81, the Transvaal Boers had successfully fought the British in order to achieve this.

The discovery of gold in the South African Republic (SAR) in 1886 raised the stakes.​​​​​​ A large influx of English-speaking people, called Uitlanders (literally 'Outlanders') by the Afrikaners, were attracted by the goldfields. This worried the Boers, who saw them as a threat to their way of life.

Jameson Raid

The Jameson Raid of 1896 was an attempt to create an uprising among the Uitlanders in the SAR. Led by Dr Leander Starr Jameson and his British South Africa Company troops, its failure was a humiliation for Britain and the supporters of confederation. It led to a further deterioration of the relationship between the British and Boer governments.

Anxious to overcome this set-back and to give the British policy fresh impetus, Colonial Secretary Joseph Chamberlain appointed an outspoken imperialist, Sir Alfred Milner, as High Commissioner for South Africa in 1897.

The Jameson Raid hardened Boer opinion and led to a resounding victory for Paul Kruger in the 1898 SAR presidential election. Kruger was even more reluctant to permit the Uitlanders to enjoy political power.


In 1899, the SAR offered an extension of the franchise to the Uitlanders. This was in return for British agreement not to interfere in the SAR's internal affairs.

Kruger also demanded that Britain drop its claim to rule the SAR and allow external arbitration of other unresolved disputes between the two governments. Confident that the Boers would be quickly defeated, Chamberlain rejected Kruger's proposals.

Boers strike

Recognising that Britain was not seeking a peaceful settlement, the SAR and its ally the Orange Free State resolved to strike first.

On 9 October, the SAR issued an ultimatum demanding the withdrawal not only of British troops from their borders, but of all reinforcements sent to South Africa since 1 June 1899. This ultimatum was rejected and on 12 October the allied republics invaded Cape Colony and Natal.

Black Week

The Boers soon laid siege to the towns of Kimberley, Mafeking and Ladysmith and, in December 1899, defeated British attempts to relieve them in the battles of Stormberg, Magersfontein and Colenso.

'Black Week', as the period of these defeats became known, was a major shock to the British public who were used to hearing of victories throughout the Empire.

Skilled enemy

British tactics, which had generally proved successful against poorly armed opponents, turned out to be disastrous when used against the Boers. The British launched frontal attacks on concealed Boer positions. These were ineffective and led to several defeats in December 1899.

Using modern rifles and smokeless powder, the Boers were able to snipe at British infantry from long distances before withdrawing to avoid any set-piece confrontation. They were highly mobile, adept in fieldcraft and used to life on the high veldt.

Although the Boers only had 88,000 soldiers and relatively few artillery pieces, they were led by outstanding generals such as Louis Botha, Jan Smuts and Christiaan de Wet.

Empire strikes back

After several reverses, the British mobilised their superior resources and sent more men to South Africa. These included troops from across the Empire, especially from Canada and Australia. Eventually, over 400,000 soldiers were involved.

At home, the population volunteered in great numbers to serve in South Africa. The war was the first campaign in which British people from all sectors of society took up arms, with many joining newly raised formations like the Imperial Yeomanry. It was a forerunner of the patriotic fervour that inspired volunteers during the First World War (1914-18).

African and Indian role

On the outbreak of war, the British made a tacit agreement with their Boer enemies that both sides would not arm the black population. As the war progressed, however, this stance proved difficult to maintain and they began employing armed black people as scouts.

It is estimated that between 15,000 and 30,000 black Africans eventually served under arms with the British Army as scouts and sentries. Another 100,000 worked as labourers, transport drivers, blacksmiths, wheelwrights, farriers and builders.

Although the Indian Army was not deployed to South Africa, a small number of Indian stretcher bearers and servants took part in the campaign. The Indian Ambulance Corps consisted of 300 free Indians and 800 indentured workers from sugar estates, who were sent to the front by their employers.

Shortly after the SAR's ultimatum expired on 11 October 1899, 7,500 Orange Free State troops crossed the border into Cape Colony with the intention of capturing Kimberley. They wished to gain control of the diamond mines, the railway and the supplies in the town. The Boers were further motivated by a hatred of Cecil Rhodes, a leading proponent of confederation, who was among those besieged.

Kimberley had a garrison of 4,800 men, 600 of whom were regulars. They were commanded by Lieutenant-Colonel Robert Kekewich.

Kekewich had to defend a civilian population of 50,000, as well as a perimeter 20 miles (32km) long. His task was hindered by a shortage of firearms.

On 15 October, Kimberley was cut off by the Boers. But their bombardment of the town did not begin until 6 November, after Kekewich had rejected Chief Commandant CJ Wessels' summons to surrender.

Although stocks of foodstuffs were initially high, rations had to be reduced early in 1900. This coincided with a marked increase in sickness and mortality. A shortage of fresh vegetables also caused scurvy among the black population.

Relief delayed

British troops under Lieutenant-General Lord Methuen marched to relieve the town. They fought battles at Graspan, Belmont and Modder River before their advance was halted for two months after defeat at Magersfontein. Lord Roberts then assumed command of a reinforced column that renewed the offensive.

After a four-month siege, Kimberley was relieved on 15 February 1900, when a patrol of the Australian Horse from Lieutenant-General John French's Cavalry Division entered the town.

After successes against the invading Boers at the Battles of Talana and Elandslaagte on 20-21 October 1899, Lieutenant-General Sir George White's Natal Field Force, charged with the defence of the colony, was itself besieged in Ladysmith.

About 13,500 troops - the majority British regulars - and 7,500 civilians - 2,500 of them Indians - were trapped. As the siege proceeded, the number of Boers in the trenches rarely exceeded 5,000. They opened their bombardment on 2 November with 17 field-guns.

Encouraged to believe that relief was coming by General Sir Redvers Buller's advance, the Ladysmith garrison made a number of sorties to distract the Boers. But the initiative passed back to the Boers after Buller's reverse at Colenso on 15 December, when he suggested to White that he should consider surrendering.

Caesar's Camp and Spion Kop

In January, the Boers attempted to take Ladysmith by storm. Their unsuccessful assaults on Caesar's Camp and Wagon Hill ended this policy. But after Buller was again defeated at Spion Kop on 24 January, the full rigours of the siege began to be felt in Ladysmith.

An alarming increase in sickness rates, coupled with serious shortages of food, led to the introduction of horseflesh into the rations.

But on 28 February 1900, Buller finally broke through after close co-operation between his infantry and artillery. This success freed up the men of the former Natal Field Force to play an active role in the prosecution of the war elsewhere.

‘Our provisions are getting very scarce… coffee, tobacco, jam, pickles and other necessaries. I don’t think I will ever again grumble at dry bread for tea, or complain if there’s no milk in the jug… The Boers are beginning to use their guns properly. This morning at 7 while some men of the Gloucestershire Regiment were eating breakfast, a shell burst on one of the sangars with terrible results, killing 7 men and wounding 10 others… it broke right in amongst them. All this afternoon shrapnel shells were flying.'

Mafeking was the most northerly town in Cape Colony and had been claimed by the SAR prior to the outbreak of war. Immediately after the expiry of the SAR ultimatum on 11 October, 6,000 Boers under the command of General Piet Cronje attempted to seize it.

Strategic importance

The town contained stocks of food, forage and railway material, which would have proved useful to the Boers. In the wider context of the war, the Siege of Mafeking was of greater strategic importance to the British, since it prevented the besiegers from participating in the campaign against them further south.

The commander of Mafeking was Colonel Robert Baden-Powell. At the outset of the siege, he had at his disposal 750 locally raised troops and a force of 400 irregulars formed from the townspeople. In addition, more than 600 black Africans were employed as cattle guards. The civilian population of the town numbered 650 Europeans and 7,000 Africans.

Baden-Powell decided to defend a perimeter around 7.5 miles (12km) long around the town. As the siege progressed, the military role of the armed black population became increasingly important.

Baden-Powell had an ambivalent attitude towards the black Africans in Mafeking, without whose assistance the town would quickly have fallen. He reduced their rations during the siege and by playing down their contribution ensured that they received little reward after it.

The Boer bombardment of Mafeking began on 16 October. After Cronje left on 19 November and command devolved to General J Snyman, the siege became less energetic. It lasted 217 days and was the longest of the war.

By the time the town was relieved on 17 May, battle casualties on both sides had reached 463. Its relief led to riotous celebrations throughout Britain and made Baden-Powell a national hero.

British success

Following the end of the sieges, the war gradually turned Britain's way. By the end of May 1900, the British had overrun the Orange Free State. And by October, the Transvaal had been annexed.

Yet the British found that they only controlled the ground their columns physically occupied. As soon as the troops left a town or district, their control of that area faded away.

Guerrilla war

Many Boers fought on and 18 months of cruel guerrilla warfare were to follow the annexations. To control the countryside the British built stone and corrugated iron blockhouses that were manned by permanent garrisons, connected by telephone and barbed-wire fencing.

Farms burnt

To prevent the guerrillas from obtaining supplies, information and assistance, the British burnt thousands of farms and destroyed crops. The burnings were also undertaken as a punishment to the locals for supporting the guerrillas.

‘We must put a stop to these raids on our railway and telegraph lines, and the best way will be to let the inhabitants understand that they cannot be continued with impunity. Troops are now available and a commencement should be made tomorrow by burning De Wet’s farm… He like all Free Staters now fighting against us is a rebel and must be treated as such. Let it be known all over the country that in the event of any damage being done to the railway or telegraph the nearest farm will be burnt to the ground.’

The British also confined Boer families and black Africans in a network of concentration camps. As well as removing a means of support for the guerrillas, it was believed the presence of Boer families in the camps would make soldiers in the field surrender.

Accommodation in the camps was poor. Water and food were in short supply, and medical and sanitary facilities almost non-existent. Sickness became widespread. In all, 28,000 Boers, mainly women and children, died in the camps. Around half that number of black Africans died in separate camps.

'I call this camp system a wholesale cruelty… To keep these camps going is murder to the children... They drop in the terrible heat, and with the insufficient unsuitable food; whatever you do, whatever the authorities do, and they are, I believe, doing their best with very limited means, it is all only a miserable patch on a great ill. Thousands, physically unfit, are placed in conditions of life which they have not strength to endure. In front of them is blank ruin… If only the English people would try to exercise a little imagination – picture the whole miserable scene. Entire villages rooted up and dumped in a strange, bare place.'

Emily Hobhouse - 1901


The policy proved to be counter-productive. It aroused widespread criticism at home and abroad because of the fatalities. Emily Hobhouse was instrumental in raising public awareness of the camps. She also organised a relief effort to aid the victims.

Her campaign forced an embarrassed government to act. Milner’s civilian authorities took over the camps’ administration from the Army and conditions slowly improved.

The policy was also militarily flawed. By relieving the Boer 'bitter enders' of responsibility for their families, it allowed them to concentrate on fighting. Later on, Lord Kitchener reversed this policy and encouraged his men to leave Boer families to be cared for by the enemy. This hampered Boer mobility and forced many to give up the struggle.

While regular troops swept the countryside in a ‘scorched earth’ policy, mounted infantry units tracked down the remaining mobile Boer guerrillas, engaging in small skirmishes and ambushes.

Eventually, these policies forced the Boers to seek terms. On 31 May 1902, the Treaty of Vereeniging was signed and the Boers accepted British sovereignty but with limited self-government. The Boer republics were fully integrated into the Union of South Africa in 1910.

First modern war

The British Army used a variety of technological innovations during the war. Although some had been used in previous campaigns, it was the scale of their employment in South Africa which was exceptional.

The distances involved in South Africa led to the extensive use of the electric telegraph and field telephone.

Balloons and trains

Hydrogen-filled balloons were used for observation and directing artillery. Railways played an important part in the campaign and were frequently attacked by the Boers.

To counter this threat, armoured trains regularly patrolled the main routes. Winston Churchill, then a war-correspondent, was travelling on board one such train when it was ambushed by Boer commandos.

Searchlights, powered by mobile generators, were used to light up the railway and facilitate track repairs at night.

Engines and horses

Steam traction engines were used to move heavy loads along roads and across countryside, thereby helping to conserve draught animals, which had only a short life expectancy in South Africa. A similar fate awaited the majority of horses used by the mounted troops.

These animals were all too frequently put to work unacclimatised, ill-fed and ill-cared for. During the course of the war, some 350,000 horses and 50,000 mules perished.

The war not only involved large numbers of men, animals and machines operating over an enormous area, it also resulted in physical destruction on a massive scale.

The farm burnings, railway sabotage and devastation in the countryside created difficulties in maintaining food supplies, particularly for the British Army who could not live off the land like their enemy.

While the Boers were unable to hold their British captives for any length of time, the British developed a network of camps for Boer prisoners in South Africa, Bermuda, Ceylon (now Sri Lanka), India, and St Helena.


The war mobilised the resources of the British Empire and cost the British government £210 million (over £25 billion today). It resulted in more than 120,000 British and Imperial casualties, including 22,000 dead. Two thirds of the deaths were caused by disease and inadequate medical provision.

Imperial lesson

The writer Rudyard Kipling remarked of the war, 'We have had an imperial lesson.' But the British Army learned from its defeats at the hands of the Boers.

Reforms in tactics, equipment and administration were introduced in the years after the conflict. These changes meant that when the Army marched to war in 1914, it was the best equipped and trained force ever to leave British shores.
