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.’”
But normal for Churchill was in a sense also rather abnormal: when he wasn’t severely depressed and low in energy and lying in bed, Churchill had very high energy levels. He wouldn’t go to sleep until two or three in the morning, instead staying up and dictating his dozens of books. He would talk incessantly in a tantivy of whirling thoughts. So much so that the then US president, Franklin D. Roosevelt, once said of him: “He has a thousand ideas a day, four of which are good.” These are manic symptoms, part of the disease of manic-depression (which includes but is not exactly the same thing as today’s “bipolar” illness terminology).
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 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 Abbasiya Barracks in Cairo before they marched south 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 .  Back in England by October, Churchill wrote an account of the operation, published as The River War in November 1899.
