On the evening of January 6, 1945, one of the bombers of the 171 Squadron on a "RCM" mission (Radio-Counter-Measures), the Halifax NA687 (6Y-N), fell 2 km north of Ambly, on the heights, near the place “Bois de la Mouchonnière”. The bomber dragged its eight crew members to their deaths.
According to the RAF (Royal Air Force), the real cause of the accident was never established. In addition to the theory that he was shot down by a German fighter, one of the hypotheses advanced would be that he collided with another Halifax bomber (MZ469 (Z5-N) of the 462 Squadron), which crashed at the so-called "Epine", near the place called "Moustaviet" (1.5 km south of Hargimont, a dirt road on the left leads into the fields, 400 m further).
