It became evident that the isolated groups in Luanda needed assistance, so in March of 1963 Manuel da Silva, his wife and two children moved to Angola at the Society’s invitation. Since they were both special pioneers, the work was quickly organized and produced fine results. Then on October 14, 1963, in Luanda, Manuel da Silva and Manuel Acácio Santos were arrested and imprisoned.

By this time Manuel da Silva had also been placed in solitary confinement for having preached the good news to fellow prisoners.

Finally, on January 23, 1964, the three brothers were informed that they would be deported to Portugal.
