the order and handed over their arms. This catalyzed the Cape Parliament to vote in favor of disarmament. The delegation announced their failure to prevent the enactment of the Peace Preservation Act at a pitso convened on 3 July. The heir to the Basuto throne, Lerotholi, spoke against disarmament, while Letsie's brother chief Masopha and his nephew chief Joel Molapo openly challenged the order and advocated for armed resistance. Masopha began to fortify the stronghold of Thaba Bosiu, while the supporters of the rebel chiefs began ignoring orders from the local magistrates. White traders abandoned Basutoland, and Basuto loyalists fled to the magistracies for protection as armed bands roamed freely in the region. Sprigg urged Letsie I to negotiate Masopha's unconditional surrender, until a force of Cape Mounted Riflemen (CMR) could arrive to assist him. Letsie I replied that this was unrealistic, as most of the Basuto, including his sons, had rallied behind Masopha. Letsie and his armed retinue, returned to their village on 19 August after several days of negotiations, fearing that they would be ambushed if they remained outside Thaba Bosiu any longer. In a last ditch effort to prevent an uprising, Sprigg visited Letsie I in person. Letsie I then held another pitso—under Sprigg's new terms the rebel chiefs were to appear in court where they would receive a token fine, pledge to compensate those whose property they had seized, and comply with the gun regulations. Masopha remained defiant and held an assembly of his own, where he and Lerotholi began to prepare for war. Masopha believed that the Cape's troops had proved themselves to be incompetent during the suppression of Morosi's revolt. He was further encouraged by rumors that the British would refuse to reinforce the Cape, and by the British defeat at the Battle of Isandlwana a year prior. Conflict September 1880 On 13 September 1880, a 212-man unit of Cape Mounted Riflemen under Lieutenant Colonel Frederick Carrington crossed into Basutoland in the vicinity of Wepener in order to reinforce the isolated magistracy at Mafeteng. Upon hearing of Carrington's advance, the Mafeteng District magistrate Arthur Barkly set off with 20 policemen to scout ahead. Some from the magistracy, he encountered 300 Basuto warriors commanded by Lerotholi on a hill range overlooking the road. The two parleyed, and Barkly informed Lerotholi of the column's imminent approach and advised him to surrender his arms and withdraw. Lerotholi
