On 7 October 1908 George Archer-Shee, a naval cadet at the Royal Naval College, Osborne, allegedly stole a 5/- postal order belonging to a fellow cadet. The Navy investigated the allegations, found George guilty and expelled him. This branded George publicly as a thief and destroyed his good name, his planned naval career and his future employability. It also destroyed the good name of his family. The ensuing case by his father against the Admiralty claimed that George was not guilty and that he had been wrongfully expelled. There was widespread public support for the Archer-Shees during the hearing of their case against the Admiralty. Settlement of the case cleared George of any wrongdoing and released the Admiralty from any legal claim for breach of contract or malicious prosecution. George's father then pressed for and obtained an ex gratia payment from the Admiralty. Navy officials always believed George was guilty although commentators have either considered that George was innocent or have left the question open. The present author expresses the view that George was guilty and proposes his own theory.
