In 1805, during his return from India, the Duke of Wellington stayed briefly in a house on the remote island of St. Helena in the South Atlantic.

By an odd coincidence, when Wellington defeated Napoleon at Waterloo 10 years later, the deposed emperor was exiled to the very same house — while Wellington occupied his former palace.

“You may tell Bony,” the duke wrote to a friend, “that I find his apartments at the Elisée Bourbon very convenient, and that I hope he likes mine at Mr. Balcom’s. It is a droll sequel enough to the affairs of Europe that we should change places of residence.”
