There’s the old tale of a country that was lost because a war was lost
The war was lost because the battle was lost
The battle was lost because a general didn’t receive orders
The general didn’t receive orders because the message was delayed
The message was delayed because the messenger stopped en route
The messenger stopped en route because his horse’s shoe came off
The shoe came off because of a sharp rock in the road.
How far back do we go in search of causes of historical events?
