While staying in Bangalore in the first half of 1898, Churchill explored the possibility of joining Herbert Kitchener 's military campaign in the Sudan.  Kitchener was initially reticent, claiming that Churchill was simply seeking publicity and medals.  After spending time in Calcutta, Meerut , and Peshawar , Churchill sailed back to England from Bombay in June.  There, he used his contacts—including a visit to the Prime Minister Lord Salisbury at 10 Downing Street —to get himself assigned to Kitchener's campaign.  He agreed that he would write a column describing the events for The Morning Post .  He sailed for Egypt, where he joined the 21st Lancers at Cairo before they headed south along the River Nile to take part in the Battle of Omdurman against the army of Sudanese leader Abdallahi ibn Muhammad .  Churchill was critical of Kitchener's actions during the war, particularly the latter's treatment of enemy wounded and his desecration of Muhammad Ahmad 's tomb in Omdurman .  Following the battle, Churchill gave skin from his chest for a graft for an injured officer.  Back in England by October, Churchill wrote an account of the operation, published as The River War in November 1899. 
If we can stand up to him, all Europe may be free and the life of the world may move forward into broad, sunlit uplands. But if we fail, then the whole world, including the United States, including all that we have known and cared for, will sink into the abyss of a new Dark Age made more sinister, and perhaps more protracted, by the lights of perverted science. Let us therefore brace ourselves to our duties, and so bear ourselves that, if the British Empire and its Commonwealth last for a thousand years, men will still say, ‘This was their finest hour.’”
By his re-election in 1951, Churchill was, in the words of Roy Jenkins, “gloriously unfit for office”. Ageing and increasingly unwell, he often conducted business from his bedside, and while his powerful personality and oratory ability endured, the Prime Minister’s leadership was less decisive than during the war. His second term was most notable for the Conservative Party’s acceptance of Labour’s newly created Welfare State, and Churchill’s effect on domestic policy was limited. His later attempts at decreasing the developing Cold War through personal diplomacy failed to produce significant results, and poor health forced him to resign in 1955, making way for his Foreign Secretary and Deputy Prime Minister, Anthony Eden .
