The story of mail carried on the Empire and Horseshoe Routes during WWII and the re-establishment of services with Britain at the end of the war. These books include a detailed history of the involvement of Australian military personnel in the war and the carriage of mail to and from them. There is much more to the story than the airmail concession available to Australian servicemen. Much of the story is about the difficulty of getting the mail from front line areas to the airline terminal – frequently it is a land, sea/air service.
