The Air Adventures of Biggles (ep13-24) 1953 Serial The Black Raider

Synopsis
A wave of terror is spreading across Africa. A gang of bandits led by someone who calls himself "The Black Elephant" is attacking farmsteads, murdering the farmers, and pillaging them off their cattle.
Biggles and the Air Police are called in to help. But the gang is well-organized and ranges over a vast area of more than half a million square miles across most of the eastern side of Africa.
Bringing the gang to justice will take the entire staff of the Air Police, three aircraft, numerous allies on the ground, and some good luck.
