The Battle of Bronkhorstspruit was the first major engagement of the First Boer War. It took place by the Bronkhorstspruit river, near the town of Bronkhorstspruit, Transvaal, on 20 December 1880. Threatened by the growing numbers of militant Boers in the Pretoria region, the British recalled the 94th Regiment of Foot, which had several companies garrisoned in towns and villages across the wider area. The regiment's commanding officer, Lieutenant Colonel Philip Robert Anstruther, led a 34-wagon column consisting of roughly 250 men on a journey from Lydenburg back to Pretoria. A similar-sized Boer commando force, led by Francois Gerhardus Joubert, was ordered to intercept and stop the British.
Despite several warnings of the threat of attack, the British travelled largely unprepared for combat, and the many wagons accompanying them slowed their progress significantly. On 20 December, 24 days after receiving the order to return, Anstruther's column was confronted by the Boers, who demanded under truce that the British stop their march. Anstruther refused, and the Boers attacked while the British soldiers were still preparing. The British suffered heavy casualties and surrendered after about 15 minutes; the survivors were captured. Anstruther was badly wounded and died of his injuries a few days later.
Background Southern Africa was first settled by Europeans in the mid-17th century when the Dutch set up a provision station at the Cape of Good Hope. Over the subsequent decades, more settlers followed and moved further inland. These settlers, known as Free Burghers, developed an independence that became a distinctive feature of their descendants, the Boers. In the early 19th century, the British captured the Dutch Cape Colony as it provided a strategic advantage during the Napoleonic Wars. The British imposed their 1833 slavery ban—which made the purchase or ownership of slaves illegal, and emancipated slaves across the British Empire—on the Cape Colony, at significant financial cost to the Boers. Along with the monetary loss, the Boers were increasingly baffled and angered by the British sentimentality towards the native African population. In contrast with the Boers' deeply held religious beliefs regarding the African natives' inferiority, the British supposedly treated them as equal to white European settlers at least when it came to disputes, and would deny the Boers from taking punitive action against raiding tribes.
During the late 1830s, no longer willing to live under British rule, thousands of Boers moved north and east in the Great Trek, abandoning the British Cape Colony and crossing the Orange River into lands unclaimed by European settlers. These (pioneers) battled native tribes such as the Matabele and Zulu, and established several independent Boer republics. One of these, the (Natalia Republic), was short-lived: it was established in 1838 and annexed by the British Empire in 1843, driving the Boers on yet further. The British again pressed their own claims, annexing the area between the Orange and Vaal rivers as the Orange River Sovereignty in 1848. Four years later, they signed the Sand River Convention, granting independence to Boers north of the Vaal, an area the British called the Transvaal, and recognising the establishment of the (South African Republic) there.
Successive British governments debated colonial policy over the next couple of decades, but despite repeated calls from administrators for the forced merger and federalisation of the southern African states under British control, a hands-off, anti-expansion policy remained in place. The discovery of diamonds in 1867 and gold in 1873 changed this thinking; rather than viewing South Africa as too complex and costly, the British saw the potential for an economic boom. Along with other socio-political factors, this led to the annexation of Griqualand West in 1873, and the South African Republic in 1877.
The Transvaal region had a population of to Boers, mostly spread around the countryside on farms, and around 5000 British settlers. Pretoria, the capital, had a population of roughly 2250. The majority of the Boer population opposed the annexation, and considered the British to be an occupying force. The Boers sent political delegations to London in 1877 and 1878, but on both occasions their pleas to reverse the annexation were rejected. By the end of 1879, British defeats of the Zulu and Bapedi, both of which had previously raided in the region, eliminated them as significant threats to the Boers. As a result, the majority of the Boer population no longer saw the need for the protective presence of British troops and administrators in the Transvaal. Demonstrations were held against what was seen as an unjustifiable and unnecessary occupation. By March 1880 the election of a new Liberal government in London, known to oppose the annexation, had quieted unrest in the Transvaal. However, Prime Minister William Ewart Gladstone, concerned with Irish and other issues, informed the Boer leaders that the British Empire would not relinquish the Transvaal. As a result, the Boer leadership began to prepare for an insurrection.
Prelude
In November 1880, following the directive of the British colonial administrator, Colonel Owen Lanyon, a local magistrate in Potchefstroom (roughly south-west of Pretoria) seized a wagon from a Boer, Piet Bezuindenhout, for alleged non-payment of taxes, and put it up for auction. An armed party of a hundred Boers, led by Piet Cronjé, arrived in support of Bezuindenhout and reclaimed the wagon. This led Lanyon to mobilise men from the Pretoria garrison to arrest the Boers, but when it became clear that he did not have sufficient men to deal with the growing threat of a general uprising, he decided to recall men from outlying garrisons, to concentrate his strength in Pretoria while he waited for reinforcements from Natal. In all, he had around 1,800 regular troops spread around the Transvaal region to protect British interests, primarily composed of the 94th Regiment of Foot and the 2nd Battalion, 21st Regiment (Royal Scots Fusiliers). Roughly 700 of these were centred in Pretoria, the rest being stationed in the smaller towns of Rustenburg, Lydenburg, Marabastad, Standerton and Wakkerstroom.
British troop movement from Lydenburg On 27 November, the commanding officer of the 94th Regiment—Lieutenant Colonel Philip Robert Anstruther, who commanded the garrison at Lydenburg—received orders to withdraw his men to reinforce Pretoria. The garrison comprised the headquarters and two companies of the 94th Regiment, roughly 300–330 men. Similar orders were sent to the other regimental companies garrisoned at Marabastad and Wakkerstroom. The soldiers based in Marabastad left that village on 30 November and arrived in Pretoria on 10 December. Anstruther meanwhile delayed his departure, waiting for more wagons to be acquired. Rather than set off with the regulation-standard number of wagons (roughly 10 to 12), Anstruther waited until he had 34, to carry personal items, rations and all the quartermaster's stores. This delayed his departure on the journey to 5 December. He left roughly 60 men to hold Lydenburg, taking approximately 245–270 soldiers, two wives, a widow and two children back to Pretoria. The British were also accompanied by around 60 native Africans to drive the wagons and look after the oxen.
Anstruther's large wagon train made travelling slow; the British averaged per day, but delays caused by swollen river crossings and muddy trails meant they sometimes covered as little as . They reached Middelburg, less than halfway through their journey, on 15 December, and remained there the following day to allow their oxen to rest. A further delay ensued the following day; the column reached the Olifants River but was unable to cross due to the high water levels. During this wait, Anstruther received a communication from Colonel William Bellairs warning him of the possibility of a surprise attack as the Boers were taking up arms in the area. Anstruther had also been warned by apparently friendly Boers that insurgents were trying to turn local sympathies against his progress. The modern historian John Laband describes Anstruther as "bluff, good-natured and unfussed, with an amiable contempt for the Boers whose ability to take strong, concerted action he discounted."
The British crossed the Olifants on 19 December and continued to Honey's farm, east of a small river known as the Bronkhorstspruit. Despite the warnings they had received, when they set off the next morning, the soldiers were only carrying 30 rounds of ammunition per man, rather than the regulation 70; only four scouts were posted, two ahead and two behind the main body; and the 40 men of the band were playing, leaving them unarmed.
Boer commando While Anstruther's column marched from Lydenburg, thousands of Boers were gathering around Pretoria, and on 13 December they elected leaders and declared independence from British rule, reestablishing the South African Republic. Francois Gerhardus Joubert (who was the uncle of Piet Joubert, one of the triumvirate of Boer leaders) was ordered by the Boer leadership to stop Anstruther from reaching Pretoria. He left Heidelberg on 18 December and rendezvoused with two other forces en route. They camped halfway between Pretoria and Bronkhorstspruit overnight on 19 December and the next morning planned their attack. Nicolaas Smit, who had combat experience from the Pedi wars, suggested flexibility rather than a set ambush, and so they continued east towards Middelburg to intercept the British column. Francois Joubert mobilised the Boer militia in Middelburg; a commando from there travelled parallel to the British, but hidden from them, though at one stage British officers noticed an unusually large number of riding horses at a Boer farm, but thought nothing of it.
Opposing forces
The British infantry were armed with the Martini–Henry Mk III rifle, firing ammunition, and fitted with a bayonet. They wore the traditional red coat of the British Army, with blue trousers. A few months after the battle of Bronkhorstspruit, a question was raised in the British parliament, which criticised the uniforms for being "conspicuous", and therefore allowed "the Boers to shoot them down without danger to themselves". Hugh Childers, the Secretary of State for War, said in response that there was no need to change the uniforms, though the red coat was phased out over the subsequent eighteen years. The exact composition of the British column at Bronkhorstspruit is unclear; Laband lists 6 officers and 246 men in the 94th Regiment, along with 2 officers and 4 or 5 men from the Army Service Corps, a surgeon of the Army Medical Department, and 3 men from the Army Hospital Corps. Another historian, G. R. Duxbury, gives slightly different numbers for the 94th Regiment—6 officers and 230 men—but broadly agrees on the other figures. According to the British historian Ian Castle, after having fought in the Anglo-Zulu War of 1879, a series of battles against Sekhukhune, and then experiencing "tedious periods of garrison duty in isolated posts", the 94th Regiment was low on morale, and facing increasing levels of desertion.
