A couple of weeks ago I posted about Biggles aka James Bigglesworth and Xenophon. The Greek historian got a name check in Biggles Flies East. I hadn't realised at the time that the lost army of Cambyses is central to the plot of Biggles Flies South. Captain WE Johns clearly knew his Herodotus (3.26 - there is a v good new translation out). From the beginning of the book:
The year was 525 B.C., nearly five centuries before the Roman Caesar landed on the shores of barbaric Britain. Cambyses, conquering son of Cyrus the Great, founder of the Persian Empire, was on the march, adding more and more territory to his wide-spread kingdom. Egypt had fallen under the pikes and scimitars of his armoured warriors, and he had celebrated the event by destroying the sacred, Apis and plundering the temples of the high priests. And now he paused at the oasis to refresh his troops, before moving on to conquer new worlds.
