Baptist Mid-Missions sent six missionaries to French Equatorial Africa in the fall of 1921.
The first stations were established at Sibut, Crampel, and Bangassou, in what is now the Central African Republic.
Although Hass died in 1924, the mission continued to expand and by the 1960s had grown to over 100 churches.
The Scriptures were translated into the native Sango language, and a hospital, six dispensaries, two Bible schools, and a seminary were established by 1961.
In 1995 the Eglises Baptistes de la RCA had 375 churches with about 6,000 members.
