"In total, the Ypres city accounts for 1488–1489 record 38 named women and numerous anonymous ones engaged in intelligence activities. Some, like Josine Hellebout, were highly active, receiving payments for up to eleven separate missions. Others appear only once but often undertook significant and risky journeys—on foot, unarmed, and often alone or in pairs.
A key advantage women had was their invisibility. Because they were not suspected of military or political activity, they could pass through city gates, enemy lines, and military encampments with less scrutiny than men. This phenomenon, Demets argues, was both practical and tactical: “Women could more easily move in and out of cities or around military camps, acting as trustworthy intermediaries between opposing sides.”
But these were not simply passive messengers. Many women were paid not just to carry letters, but to “to find out about the enemies’” or “ascertain the situation” in enemy-held territory. During the Siege of Ghent and subsequent campaigns in 1488, for instance, Tuenine Spepers was sent to Damme and Aardenburg to “gather news about the King of the Romans [Maximilian of Austria]” and to Diksmuide to report on the local situation. Other women, such as Crispine Sroys and Beatrice Cambiers, carried out missions directly to military commanders or towns under threat, often accompanied by unnamed female companions, possibly locals or other camp followers.
The growing professionalization of this network became particularly evident in 1489, when the war intensified. “By 1489, women increasingly emerged as professionals within the medieval intelligence service in Ypres, as records show that the same individuals were repeatedly paid a ‘salary’,” Demets explains."
