The Battle of Berea was a battle between British forces under Sir George Cathcart and Basuto-Taung forces under King Moshoeshoe I that took place on 20 December 1852. The battle began when British forces broke into three columns and crossed the Caledon River in southern Africa, with the goal of seizing Basuto cattle as a form of punishment for past Basuto cattle raiding.

A combination of stiff Basuto resistance, poor planning and miscoordination on the side of the British forces led to far fewer cattle being seized than originally planned. The British withdrew in order to regroup after suffering relatively high casualties. However a peace agreement was reached before the resumption of hostilities. The Basuto paid limited restitution, while agreeing to halt any further cattle raids against British subjects.

Background

Foundation of the Basuto State
During the early 19th century, a diverse group of Sotho, Nguni and Tswana speaking tribes settled in the Caledon River region in southern Africa. The latter two formed the minority of the population and were gradually assimilated by the culturally dominant Sotho. King Moshoeshoe I united the various Sotho speaking chieftainships into a single nation during a period of political turbulence known as Lifaqane. By approximately 1828, Moshoeshoe's act had transformed the denigratory exonym of Sotho into the name of the nascent Basuto nation. In the region's African societies cattle raiding played a crucial societal role in increasing a chief's prestige. By stealing cattle from rival tribes and then redistributing it to his followers under the mafisa system, the chief retained its nominal ownership while strengthening his relationship with his subjects.

In the 1820s the Basuto faced a number of cattle raids from the Koranna, a group of Khoekhoe people who had migrated from the Cape following the European settlement of the region. It was during this time that they first encountered horses and guns in a combat setting. After a number of initial setbacks, the Basuto managed to either capture or acquire horses and guns of their own, and began stockpiling gunpowder. By 1843, Moshoeshoe had accumulated more horses and guns than any other chieftain in South Africa. Nevertheless, most of the guns in Basuto possession were outdated flintlocks, which had flooded the South African market after the introduction of percussion lock muskets.

Basuto-British Relations
In 1843, Moshoeshoe signed a treaty with the governor of the British Cape Colony, Sir George Napier, whereby the British recognized the Basuto as their allies. The Basuto were tasked with countering Boer incursions into the Cape during the course of the Great Trek, receiving an annual grant of £75 in money or ammunition. In 1845, Napier's successor Sir Peregrine Maitland signed another treaty with Moshoeshoe which intended to settle territorial conflicts between the Boers and various African tribes on the Cape's northern border. Moshoeshoe reluctantly signed the treaty as it deprived the Basuto of both a tract of land and their annual grant. In 1848, the new Cape governor Sir Harry Smith pressured Moshoeshoe into signing an agreement whereby he recognized British paramount authority over the lands north of the Orange River; while retaining his traditional rights. The agreement also envisioned the creation of an alliance between the British and the Basuto. A series of similar ambiguously worded treaties with local African tribes effectively established the Orange River Sovereignty.

In the north-east, the Basuto and their Taung allies regularly engaged in tit for tat cattle raids against their old enemies the Batlakoa and the Koranna. The British Resident in the Orange River Sovereignty, Major Henry Douglas Warden, believed that the Basuto were more to blame for the continuous inter tribal warfare in the region. In 1849, Warden began delineating borders between the various tribes in the north-east frontier, ignoring Moshoeshoe's long standing claims to several territories in the process. Moshoeshoe believed that the British had failed to protect him against Batlakoa and Boer encroachment, while many of his subjects accused him of cowardice in the face of British oppression. On 25 June 1851, Warden demanded that the Basuto restore 6,000 head of cattle and 300 horses to the victims of their past cattle raids. Warden had assembled a mixed force of British, Boer and African troops numbering approximately 2,500 men at Platberg. On 28 June, Warden moved his force against the Taung in an effort to seize stolen cattle. On 30 June, Warden's force was defeated by a Basuto-Taung army at the Battle of Viervoet. 

In October Moshoeshoe wrote to both Smith and Warden, explaining that he had acted in self-defense and intended to maintain cordial relations with the British. In February 1852, assistant commissioner William Hogge conceded that the Cape government had made mistakes in their treatment of the Basuto. Hogge agreed to redraw the boundaries in south-western Basutoland and to cease colonial interference in inter-tribal conflicts. Hogge insisted that the Basuto restore the cattle and horses they had stolen from the Rolong and the Boer settlers since September 1850 within a span of two weeks. Moshoeshoe restored four hundred cattle and horses by 20 March, however he refused to proceed with the process after he realized that the restoration of Basuto lands was conditional upon the return of the cattle. The Basuto were determined to fight rather than give away their cattle, while Smith's newly appointed replacement, Major-General Sir George Cathcart, was waiting for the hostilities with the Xhosa to wane before dealing with the Basuto.

Prelude
Having largely suppressed Xhosa opposition in the east, in late November 1852 Cathcart led an army numbering some 2,500 men from Burgersdorp northwards. The force consisted of infantry detachments of the 2nd (The Queen's Royal) Regiment of Foot, the 43rd (Monmouthshire) Regiment of Foot, the 73rd (Perthshire) Regiment of Foot, the 74th (Highland) Regiment of Foot and the 1st Battalion of The Rifle Brigade. Also included were elements of the Cape Mounted Rifles (CMR) and the 12th Royal Lancers as well as two six-pounder field guns, two twelve-pounder howitzers and Congreve rockets belonging to the Royal Artillery and Royal Sappers and Miners.

On 13 November, Cathcart convened a meeting in Platberg with the intention of determining the number of cattle the Basuto needed to restore. The committee decided that the Basuto were to commit 10,000 cattle and 1,000 horses within three days. In the event of Basuto resistance, Cathcart warned that he would seize thrice the original number. Two days later, Moshoeshoe visited Cathcart's camp and requested additional time to collect the cattle. Cathcart rebuffed Moshoeshoe and threatened to collect the cattle by force. Moshoeshoe warned that "a dog when beaten would show its teeth". Cathcart remained sure that the Basuto would offer no resistance and left more than half his army at the Platberg camp. Moshoeshoe convened a pitso (formal assembly) at Thaba Bosiu imploring his followers to collect as many cattle as they could. By 18 November, 3,500 cattle had been collected and Basuto envoys pleaded for more time. The British remained adamant and when the Basuto failed to deliver additional cattle the following day; Cathcart established a camp on the right bank of the Caledon (modern day Cathcart's Drift)  north-west of Thaba Bosiu. Moshoeshoe's brother Mopeli visited Cathcart at his new camp and agreed to lead the British to Thaba Bosiu the following day in order to continue peaceful negotiations.

After Mopeli's departure, Cathcart changed his mind and ordered his troops to march on Thaba Bosiu at 4 a.m. on 20 December. The fourth company of the 74th Regiment was tasked with guarding the camp on the Caledon while the rest of the force was divided into three columns. The first column under Lieutenant-Colonel G. Napier, numbering 119 men of the CMR and 114 of the 12th Lancers, was to move around the Berea plateau that separated the camp from Thaba Bosiu from the north, rounding up any cattle his soldiers came across. Unbeknownst to the British the plateau extended for many miles to the north and thus Napier would have to inevitably cross the mountain in order to carry out his task in time. The central column was commanded by Lieutenant-Colonel William Eyre and had a strength of approximately 400 men, most of whom were infantry. It was supported by small detachments of Lancers and CMR cavalry, mounted Mfengu herdsmen and artillerymen who carried two Congreve rockets on mules. It was tasked with traversing the plateau and then driving the cattle through passes on its southern side. The third column was personally commanded by Cathcart. It included three companies of the 43rd Regiment, two six-pounder guns with their crews and a small mixed cavalry detachment, totaling under 400 men. Cathcart's column was to advance along the western side of Berea before converging with the other columns in front of the mountain. The pincer movement of Napier's and Cathcart's columns was to prevent the Basuto from driving their cattle away.

At dawn on 20 December, the British crossed the Caledon and began their push on Th
