Seqiti War and the later Basotho Wars

The 1858 peace did not end disputes over the Basotho–Orange Free State border. Sir Philip Wodehouse's 1864 boundary award favoured the Free State, but many Basotho remained on or returned to land placed west of the line. Complaints of cattle theft, attacks and unlawful occupation continued, and efforts by both governments to control followers on the frontier repeatedly failed.

The Orange Free State opened the Seqiti War in 1865 to enforce the boundary and remove Basotho communities from the disputed territory. Free State commandos seized cattle, destroyed crops and reduced mountain positions, while Basotho forces defended strongholds and conducted raids into Free State districts. Commandant Louw Wepener was killed during an unsuccessful assault on Thaba Bosiu.

Food shortages compelled Moshoeshoe to accept the Treaty of Thaba Bosiu in 1866, surrendering extensive territory. Implementation broke down: some Basotho crossed back over the new line, the Free State was slow to allocate conquered farms, and two white residents were killed near Ladybrand in 1867. The Free State renewed the war and captured nearly all remaining lowland territory, though Thaba Bosiu again held out.

Moshoeshoe repeatedly appealed for British protection. In March 1868 Britain intervened before the Free State could complete the conquest.

Significance

The later Basotho wars involved competing land claims, breaches of successive settlements, raids and killings by participants on both sides, and a Free State campaign that inflicted severe material losses on the Basotho. British intervention preserved the kingdom's political core but confirmed the loss of substantial western territory.
