The original book that the movie is based on is worth reading and has a lot that did not make it into the movie.
Captain Georg von Trapp was born in what is now Zadar, Croatia, when it belonged to Austria. After 1918 Austria no longer had a sea coast which reduced their need for a navy.
A Hungarian battleship, the Szent Izvan, was sunk by Italian torpedo boats in 1918.
Hungarian Admiral Miklos Horthy went on to become ruler of an independent Hungary until 1944.
Remember jokes about the “Swiss Navy”? Well, truth is always stranger than fiction.
Anyway, the memory of the Von Trapp family will live on.
A-HA! Thank you for the explanation.
Zara, Georg von Trapp’s birthplace became Italian after WWI and was absorbed by Yugoslavia after WWII.
Von Trapp was a submariner. During WWI his U-boat sank a French cruiser and an Italian submarine.
