By the end, 16million people had been killed and 20million wounded in a war that had devastated and destroyed whole cities. Civilians and soldiers, often from poor backgrounds, paid the terrible price for a battle that was brought on by the rich and powerful rulers of competing imperialist powers...Very few benefited from the killing.

Ravens were first brought to the Tower of London in about 1883 to serve as props for tales of Gothic horror told by Beefeaters to the tourists. During World War II, people used these ravens as spotters for enemy bombs and planes, and their employment was quickly mythologized as a prophecy--that the British Empire would fall if the ravens ever left the Tower.
