​​Monument to the six executed in Rimberlieu

On 28 August 1944 at around 18:00pm, a group of 21 maquisards attached to group n° 1 of the FFI of Compiègne, was attacked by about 50 Germans following a denunciation by a French informer. The day before, the Resistance fighters, under the command of Lieutenant Leroy-Sainte-Marie, had taken refuge in the ruins of the Rimberlieu Castle, located in Villers-sur-Coudun in the Oise region and destroyed in 1918.

During the assault, the majority of them managed to escape, but six were surrounded and captured. The assailants began by disarming them and seizing their ammunition and weapons. Since they were regarded as "terrorists", the FFI were then tortured and summarily executed. Their remains were exhumed two days later during the liberation of the municipality by American troops.

On 10 December the same year, a monument in their memory was inaugurated near the ruins of the castle, following a public subscription by the municipalities of Giraumont, Villers-sur-Coudun and Coudun. The same day, a commemorative plaque bearing the words "In this property, a monument commemorates the martyrdom of 6 FFI. You who pass by, come in and remember" was installed on the entrance gate of the Rimberlieu park. After the gate was dismantled, it was replaced by a memorial stone at the entrance of the former domain.

Every year on the last Sunday of August, a commemorative ceremony is organised in Rimberlieu to pay tribute to the six murdered resistance fighters: Jacques de Préval, Pierre Forest, Albert Lagny, Roger Lescot, Irénée Marié, and Paul Plonquet.
