As of 1 January 1894 the Société anonyme belge pour le commerce du Haut-Congo (SAB) had 83 factories and posts, including some in the French territory to the west of the Congo and Ubangi rivers.
A map shows the company had posts along the upper Ruki River (i.e. the Busira) at Bilakamba, Bombimba, Bussira Manene, Moniaca, Bocoté and Yolongo.
[2] The Compagnie du Congo pour le Commerce et l'Industrie (CCCI) was given the right to 150,000 hectares (120,000 acres) of land in return for its services in studying the Matadi-Léopoldville Railway project.
[7] Under the agreement of 27 December 1901 the SAB was responsible for industrial, agricultural and commercial exploitation of the Bloc and received a share of the proceeds in compensation.
It is estimated that hundreds of thousands died as victims to the agents of the Anglo-Belgian India Rubber Company (ABIR) or of the SAB in the Bus-Bloc.
[11] The American doctor Louis Jaggard (1877–1951) at the Monieka mission spoke in 1917 with scorn of the 30 or so traders at Bussira, 4 miles (6.4 km) away, who came to him for treatment.
The rebels attacked state posts, trading stations, factories, homes and a Catholic chapel.
