Modern military wives typically don't ship out alongside their husbands, but the young wife of a British naval officer did just that during the Napoleonic Wars of the 19th century. Now a historian who tracked down 40 unpublished volumes of her diaries has gotten the go-ahead to write a book investigating her life.
Elizabeth "Betsey" Wynne accompanied her husband aboard his warship during a disastrous British assault on the Spanish Canary Islands. She spent the voyage home-nursing the wounded Rear-Admiral Horatio Nelson, whom lost his right arm during the attack and would go on to become one of England's greatest military heroes of all time.
