Micheline Aline Dumon (20 May 1921 – 16 November 2017), (code names Lily and Michou), was a member of the Belgian Resistance during World War II with the Comet Line (Réseau Comète).

Her father would die in prison; her mother was released in 1943; and her sister survived the war in Mauthausen and Ravensbrück concentration camps.

[7] "Lily" Dumon took over for her family members in the Comet Line, helping Allied airmen shot down over Belgium elude capture and escape Nazi-occupied Europe to neutral Spain from where they could be evacuated to Great Britain.

"Fifty times or more [she] outwitted the German agents by suddenly enacting a tender, tearful love scene in a streetcar or on a station platform with some airmen she had only known for an hour or two.

"[10] With the near collapse of the Comet Line in June 1943 due to arrests by the Germans, Dumon assumed more of a leadership position.

"She became a sort of odd-job woman: looking for hide-outs, escorting pilots, recruiting new agents, collecting food coupons, restore[ing] the escape route after each wave of arrests.

"[11] In January 1944, with the situation becoming too dangerous for her in Brussels, she moved to Paris, then quickly to Bayonne in southwestern France, where Elvire de Greef was the leader of the Comet Line.

At a Comet Line meeting in February 1944 in Paris, Dumon met a familiar looking man who said his name was Pierre Boulain.

She didn't follow up on her suspicions immediately, but in March in Paris, during her brief incarceration, she had an opportunity to ask a Comet Line helper in prison the identity of her betrayer.

She passed this information along to Jean de Blommaert and Albert Ancia, MI9 agents in France implementing Operation Marathon.

She left for southwestern France the next day and Elvire de Greef arranged a quick exit over the border to Spain.

[21] In England, she met her future husband Pierre Ugeux, a paratrooper and French Major in the Special Operations Executive (SOE).
