This film serves as a historical sequel to The Unknown Soldier, The Children of the Resistance.
The French Ministry of Defense's Audiovisual Production and Communication Agency (ECPAD) co-produced the short film. This marked the first time ECPAD co-produced a fictional film, as it typically specializes in documentaries and news reports. ECPAD was responsible for the film's post-production and DVD editing.
The film received the "80 Years of Liberation" label from the French Ministry of Defense and the National Office of Veterans and War Victims for its contribution to the remembrance of World War II.
Thomas Lemoine secured the use of the Sabre, a landing craft from the French Navy, with the support of Defense Minister Hervé Morin, to film the scene of French troops landing in Provence. The Sabre, an infantry and tank landing craft (EDIC), measures 59 meters in length, is equipped with two 12.7mm machine guns, and had a crew of 19 members on board for the film's needs.
The landing scenes were re-created on the historic beach of Dramont in Saint-Raphaël. The re-enactment involved over 150 extras in uniform and around 15 World War II military vehicles, including an M4 Sherman tank transported via special convoy from Bordeaux.
