commander of the 3rd Military Region decided to go forward with the sending of the 4th CCE to Malanje, which arrived there on 5 February. The provisional battalion started gradually the operations to subdue the uprising. The land forces were supported by the Portuguese Air Force, which employed Auster light observation and PV-2 ground attack aircraft.
