When the city itself was inundated in the early summer and after a catastrophic dike failure at just before 6:00 AM on 27 July, around 782,189 urban citizens and rural refugees were left homeless. The flood covered an area of and the city was flooded under many feet of water for close to three months. Large numbers gathered on flood islands throughout the city, with 30,000 sheltering on a railway embankment in central Hankou. With little food and a complete breakdown in sanitation, thousands soon began to succumb to diseases. The city of Nanjing, then the capital of Republican China, was also severely affected by the disaster. One of the most disastrous single events during the flood occurred on 25 August 1931, when the water rushing through the Grand Canal washed away dikes near Gaoyou Lake. In Gaoyou County alone, 18,000 people drowned and 58,000 died due to famine and diseases the following year. Rebuilding of dikes at Lake Gaoyou Thomas Harnsberger, a missionary of the Presbyterian Church in Taizhou, Jiangsu, was one of the two central figures (alongside General Wang Shuxiang, a PhD in hydraulics) who supervised the rebuilding of the dikes at Lake Gaoyou, as well as securing the funds for it. However, the flood remains widely unknown to the Chinese. Steve Harnsberger, the grandson of Thomas Harnsberger, wrote in 2007, "The 1931 flood killed 15 times the number of people lost in the Indonesian tsunamis of December 2004, and yet scarcely a word has been written of it. History focused instead on other disasters that year. China’s attention was on a civil war between the Communists and Nationalists and the Japanese were invading in the North, while the world was deep into the Great Depression." Government reactions Republican Era (1930s–1940s) The 1931 flood was one of the first major tests for the Kuomintang Government. As the scale of the disaster became apparent, the government established the National Flood Relief Commission under the auspices of T.V. Soong, a prominent politician in the Kuomintang and brother-in-law of Chiang Kai-shek. The commission employed a range of Chinese and foreign experts, including figures such as famous epidemiologist Wu Liande, health minister Liu Ruiheng, public health worker John Grant, and hydraulic engineer Oliver Todd. It also secured the assistance of the League of Nations. Even the famous aviators Charles Lindbergh and his wife Anne Lindbergh became involved, as they were commissioned to
