He communicates with his secretary, Gilberte, by leaving her notes under his typewriter. Gabriel is reputed to have killed at least one German, if not several. Once married, he moved to a more comfortable room in a house in Mesvin.
On the evening of June 4, 1944, a knock came at the door of this house. The German authorities, accompanied by militiamen (five or six men), came for a former letter carrier to question him about thefts from a post office. Gabriel Ottelet thinks it's him they've come for. He slips through the snuffbox onto the roof to escape. His escape obviously makes him a suspect and will condemn him. The militiamen are equipped with a powerful searchlight. The fugitive is spotted on the roofs. Shots are exchanged. A German is mortally wounded. Gabriel Ottelet was shot dead a little further on, at the edge of today's wood, where you can see the commemorative stele dedicated to him.
