This paper examines changing conceptions of honour and masculinity during the Colombian Wars of Independence in the early 19th century. It explores the position of the foreign women who accompanied British and Irish expeditions to join the war against Spanish rule, and shows how colonial, imperial and republican conceptions of masculinity were affected by the role that women played in these volunteer expeditions and in the wars in general. The paper considers women's experiences during war and peace, and examines their experiences in the light of changing conceptions of masculinity at home, in the British empire and in Hispanic America in the early nineteenth century. The social mobility of the Wars of Independence shifted the ground on which these concepts rested for all groups involved. The participation of foreign women alongside male adventurers was a further ingredient in this disorientating period.
