Wartime cross-dressers

Hannah Snell (1723–1792) was a British woman who disguised herself as a man and became a soldier

Many people have engaged in cross-dressing during wartime under various circumstances and for various motives. This has been especially true of women, whether while serving as a soldier in otherwise all-male armies, while protecting themselves or disguising their identity in dangerous circumstances, or for other purposes.

Conversely, men would dress as women to avoid being drafted, the mythological precedent for this being Achilles hiding at the court of Lycomedes dressed as a woman to avoid participation in the Trojan War.
