nations, and thus deprive his country of its present exclusive advantages. As one of the diplomatic moves against the project when it nevertheless went ahead, it disapproved of the use of "forced labour" for construction of the canal. Involuntary labour on the project ceased, and the viceroy condemned the corvée, halting the project. International opinion was initially skeptical, and shares of Suez Canal Company did not sell well overseas. Britain, Austria, and Russia did not buy a significant number of shares. With assistance from the Cattaui banking family, and their relationship with James de Rothschild of the French House of Rothschild bonds and shares were successfully promoted in France and other parts of Europe. All French shares were quickly sold in France. A contemporary British skeptic claimed "One thing is sure... our local merchant community doesn't pay practical attention at all to this grand work, and it is legitimate to doubt that the canal's receipts... could ever be sufficient to recover its maintenance fee. It will never become a large ship's accessible way in any case." Construction (1859–1869) Work started on the shore of the future Port Said on 25 April 1859. The excavation took some 10 years, with forced labour (corvée) being employed until 1864 to dig out the canal. Some sources estimate that over 30,000 people were working on the canal at any given period, that more than 1.5 million people from various countries were employed, and that tens of thousands of labourers died, many of them from cholera and similar epidemics. Estimates of the number of deaths vary widely with Gamal Abdel Nasser citing 120,000 deaths upon nationalisation of the canal in a 26 July 1956 speech and the company's chief medical officer reporting no higher than 2.49 deaths per thousand in 1866. Doubling these estimates with a generous assumption of 50,000 working staff per year over 11 years would put a conservative estimate at fewer than 3,000 deaths. More closely relying on the limited reported data of the time, the number would be fewer than 1,000. Company Towns From its inauguration, till 1925, the Suez Canal Company built a series of company towns along the canal to serve its operation. They included ports and their facilities as well as housing for employees segregated by race or nationality. These were Port Said (1869) and Port Fuad (1925) at the canal's northern entrance by the Mediterranenan, Ismailia (1862)
