French rule was brutal and led to many thousands of deaths. The construction between 1921 and 1934 of the 511 km long railway, the Chemin de Fer Congo-Océan between Brazzaville and Pointe-Noire is for example said to have cost the lives of around 23,000 locals and a few hundred Europeans. Any resistance against French colonial rule, however small, was brutally repressed. Ultimately the French government lost more money than it gained in rents and taxes from the Concessionary system upon which the colony had become reliant, and French public opinion was shocked by reports of the wide-scale brutalities which the system had given rise to. By 1930 most of the Concessionary companies had gone bankrupt and the practice had largely ceased.
