The Conquest of Sudan (1896-98)
Lord Salisbury ordered a campaign to secure the source of the Nile and crush Mahdist forces permanently. Forward policy in Sudan was driven by two main threats: the old Anglo-French rivalry over Nile headwaters, and fears of Mahdist forces.
In 1896, an expedition led by Lord Kitchener was launched to address these threats. The defeat of Italians at the Battle of Adowa convinced Salisbury that now was the time to strike.
British objectives were initially set at Dongola, but the expedition was to proceed carefully, ensuring supply lines remained intact. It would culminate in the defeat of the Mahdi at Omdurman, one of the bloodiest and most unequal battles of all time.
Britain declared the whole Nile valley its 'sphere of influence'. London successfully gained diplomatic recognition from Italy, Germany and Belgium, but not from France. In 1894, Sir Edward Grey told Parliament that French interference in the Nile would be 'an unfriendly act'.
Strategic Reality: Britain realised that declaring spheres of influence was pointless without actual military presence on the ground.
