[1] A committed freedom fighter who was actively involved with European resistance movements during World War II, Verspyck survived imprisonment at one Nazi concentration camp only to perish at another.

Her father, a native of Bergen op Zoom in the southern part of the Netherlands, was a partner in the leading brokerage firm of Dunlop & Kolff, which operated in the Dutch East Indies areas of Batavia, Semarang and Surabaya, trading in fish, sugar, tea and other high-demand goods.

[10] According to Dr. Bob de Graeff, professor of Intelligence and Security Studies in the department for History of International Relations at Utrecht University in the Netherlands, Verspyck was active with the Comet line in Brussels:[11] She had already been arrested in November 1941 but was released less than one year later.

Her father, who had also been taken prisoner, also survived the war.Historian Megan Koreman has been able to confirm that two of the people with whom Verspyck worked as part of the Comet line were Jan Strengers, an "expatriate banker," and Paul Van Cleeff.

"[13] In addition, Philippe Connart, Michel Dricot, Edouard Renière, and Victor Schutters, creators of the resistance research website, Le Réseau Comète (The Comet Network), have indicated that Mathilde A. E. Verspyck's mother, Mathilde Adrienne (Prins) Verspyck, may also have been involved in European resistance activities during World War II (or that the names of mother and daughter were periodically confused by historians and genealogical researchers over the years).

Taken to meet "King Kong" the next day, Greter was directed to provide the Lindemans with 100 gulden each for false papers, which would enable him to reach Cherbourg, France and Spain via the Dutch-Paris escape line with the help of guides from the resistance.

After further transfers between resistance members, Greter crossed the Pyrenees by the road of Saint-Jean-de-Luz and the Endarlaza footbridge with the help of Jean-François Nothomb and Florentino as part of the Comet line's 75th passage, which also included Geoffrey Madgett, Denny Hornsey, Leon MacDonald and George Gineikis.

According to the General Orders issued on 1 November 1946 and 20 March 1947 by the United States Department of Defense as part of this award: Mademoiselle Verspyck joined an escape organization soon after the capitulation and is considered by the head of the group to have rendered considerable and remarkable service to his evasion line.
