With American men deployed overseas for WWII, women were expected to uphold the battle on the home front. This task involved recruiting women for jobs that traditionally would have gone to men, such as code-breaking and cryptanalysis. The women involved in the operations at Arlington Hall were sworn to secrecy. Thus, many of their tremendous and important contributions to the war went unnoticed until decades after peace had been made. Even when the Code Girls were allowed to speak of their roles in the war, many people did not believe them, or simply did not care.
After the war, most of the Arlington Hall girls moved on to other professions. During the Cold War era, women were expected to take on a more domestic character, returning to traditional roles in the home and taking care of a household and children. Having a professional occupation was seen as stealing jobs from men, and large, government run childcare was considered Communist. Despite the women's intelligence, education promised by the GI Bill was given priority to men who fought on the field.
Despite these circumstances, Arlington Hall provided an opportunity for women to showcase their skills to the world. The Code Girls represented the large intellectual potential females possessed, which had frequently been ignored previously in history.
