When a successful military revolt, led by Arabi Pasha, threatened to complete the disorganisation of the country (1882), France and Britain decided that they ought to intervene to restore order, the other powers all agreeing. But at the last moment France withdrew, and the task was undertaken by Britain single-handed.[7] In a short campaign Arabi was overthrown; and now Britain had to address herself to the task of reconstructing the political and economic organisation of Egypt. It was her hope and intention that the work should be done as rapidly as possible, in order that she might be able to withdraw from a difficult and thankless task, which brought her into very delicate relations with the other powers interested in Egypt. But withdrawal was not easy. The task of reorganisation proved to be a much larger and more complicated one than had been anticipated; and it was greatly increased when the strange wave of religious fanaticism aroused by the preaching of the Mahdi swept over the Soudan, raised a great upheaval, and led to the destruction of the Egyptian armies of occupation. Britain had now to decide whether the revolting province should be reconquered or abandoned. Reconquest could not be effected by the utterly disorganised Egyptian army; if it was to be attempted, it must be by means of British troops. But this would not only mean a profitless expenditure, it would also indefinitely prolong the British occupation, which Britain was desirous of bringing to an end at the earliest possible moment. [7] See above, p. 164 The romantic hero, Gordon, was therefore sent to Khartoum to carry out the withdrawal from the Soudan of all the remaining Egyptian garrisons. On his arrival he came to the conclusion that the position was not untenable, and took no steps to evacuate. There was much dangerous delay and vacillation; and in the end Gordon was besieged in Khartoum, and killed by the bands of the Mahdi, before a relief force could reach him. But this triumph of Mahdism increased its menace to Egypt. The country could not be left to its own resources until this peril had been removed, or until the Egyptian army had been fully reorganised. So the occupation prolonged itself, year after year.
