Basil Cave was born on 14 November 1865. He was the son of Thomas Cave, the Liberal Member of Parliament for Barnstaple. Basil had five sisters and four brothers, including George Cave, who was a distinguished lawyer, Conservative MP, Home Secretary in David Lloyd George's First World Warcoalition government, and a Viscount. George Cave would later marry the sister of Lloyd Mathews, who was well acquainted with Basil and served as First Minister of Zanzibar for much of his posting there. Basil Cave was a civil servant with the British Foreign Office and on 20 March 1891 was appointed Vice-Consul of "British Sphere in East Africa, situated to the north of the German Sphere, to reside at Mombasa". On 19 February 1892 he married Mary Creighton McClellan at the Consulate on Zanzibar, with a blessing following at Christ Church Anglican cathedral. The couple had two children, Joy Mary Cave and Kenneth McClellan Cave, Kenneth later served in the Royal Artillery, reaching the rank of Brevet Major and winning the Military Cross. Upon the death of Ali bin Said of Zanzibar on 5 March 1893 it was decided to land 200 British marines to maintain order, looting and violence being customary upon the death of a Sultan, and to ensure the succession of Hamad bin Thuwaini. During these events Cave was placed in command of a guard of marines and native soldiers at the British Agency.
Anglo-Zanzibar War
Cave became the resident Consul of Zanzibar on 1 June 1895, facing a significant diplomatic crisis the next year. On 25 August Sultan of Zanzibar Hamad bin Thuwaini died, his nephew Khalid proclaiming himself sultan. The British authorities had the right to appoint the Sultan and had chosen Hamoud bin Mohammed. The Consul-General, AH Hardinge, was away in Britain at the time and it fell to Cave, as the most senior British diplomat present, to issue a warning to Khalid. He did so in person at the Sultan's palace alongside General Mathews, but was ignored and Khalid began fortifying the area. Cave continued to send messages to Khalid informing him that the British government considered this an act of rebellion and requesting that he stand down his troops and renounce the sultancy. This was ignored and Cave telegraphed his superiors at the Foreign Office for authorisation to use force. He also informed all other foreign official not to recognise Khalid, to which they agreed. During this time of unrest Mrs Cave lent her sitting rooms at the Consulate as a refuge for the European ladies of the town and instructed her cook to provide for them. The British government's approval came the next day and Cave received reinforcements in the form of a small flotilla of Royal Navy vessels led by Rear-AdmiralHarry Rawson. Cave entered further negotiations with Khalid but these proved unsuccessful and he was forced to issue an ultimatum to leave by 9 am the next morning or he would open fire. On the morning of 27 August Cave refused further attempts at compromise from Khalid and, receiving the message that "We have no intention of hauling down our flag and we do not believe you would open fire on us"; Cave replied "We do not want to open fire, but unless you do as you are told we shall certainly do so". At 9.02 the bombardment of the palace commenced, signalling the start of the Anglo-Zanzibar War. The war, the shortest in history, ended 38 minutes later after 500 defenders had been killed or wounded and the palace set alight, without British loss. Khalid fled the palace and, with some of his supporters, sought refuge at the German consulate. The Germans refused to extradite Khalid and eventually, despite Cave's protests, he was smuggled out by the German Navy to Dar es Salaam in German East Africa.
Post-war Zanzibar
Having successfully installed the chosen sultan, Hamoud, Cave was rewarded with appointment as a Companion of the Order of the Bath on 1 January 1897. He was active in campaigning against slavery in Zanzibar, which was finally abolished in 1897. One of Cave's duties was to accompany Prince Ali bin Hamud to Britain as a representative of Hamoud at the coronation of King Edward VII in 1902. Hamoud died whilst Cave and Ali were en route and Cave informed the Prince once they reached Djibouti on the return journey. It was also his responsibility to formally inform Ali that the British government had chosen him as his father's successor and that Mr A. Rogers, the First Minister, would act as regent until Ali was 21. Cave was promoted to Consul-General on 9 July 1903, with the role of commercial agent being added to his duties on 8 July 1904. During a mutiny of the Zanzibar Army in 1907 Cave received a request for British assistance from the Sultan and, no British vessel being within 100 miles of the island, was forced to ask for assistance from the German Navy. The Germans responded, sending a vessel to the Stone Town harbour which overawed the mutineers and allowed their officers to restore order.
Later life
Cave left Zanzibar in 1909, being appointed Consul-General for Algeria, resident at Algiers, on 1 April. His efforts in that country resulted in Lieutenant-General Gordon Casserly dedicating his book "Algeria To-day" to Cave and his wife "in token of admiration of the good work that they have done for the empire by their efforts to strengthen the friendship between the French and the British peoples". Cave was appointed a Knight Commander of the Order of St Michael and St George on 1 January 1925, allowing him to use the title of "Sir". Cave was also a Fellow of the Royal Geographical Society. Basil Cave died in 1931; two photographs of him are in the collection of the National Portrait Gallery.
