To ensure that the entire town would be associated with the memorial to be erected in honor of its children who had died gloriously for France, the fundraising campaign was supplemented by 10,364 francs. On May 29, 1921, an agreement was reached with a growingly renowned sculptor from Mons, Robert Wlérick, to create the Morcenx war memorial. Léonce Léglise, an architect from Mont-de-Marsan, was responsible for supervising the work carried out by Émile Larrodé's Morcenx company. The company was responsible for constructing the base to support the monument. Stone blocks from the Vienne quarries were delivered to the train station. They had to be transported from the station to the chosen location opposite the town hall and the community hall. The project was a demanding one for the workers, who had to cross a barely paved square and lift the blocks without any lifting equipment. Once the base was completed, the sculptor, Robert Wlérick, could then intervene.
This war memorial features, on the north-facing side, an angel sculpted in high relief, his arms raised and laden with a laurel wreath, surmounting the commemorative plaque: To the children of Morcenx who died for France. To underline the magnitude of the sacrifice, the palm of martyrs is engraved on the south side. The sides bear the names of 109 Morcenx residents, victims previously unidentified. When it was inaugurated in 1921, 15 names of missing soldiers had to be added. Since then, other wars have taken place… The list now includes 147 names: fourteen died on the 1939-1945 front or during deportation, three during the Indochina War, and one in Algeria. The town also pays tribute to five overseas soldiers who lost their lives in both of these wars.
In 1948, elected officials noted that, since the town centre developments undertaken in 1936, the war memorial had been very poorly located, too close to the covered market. It found its current position south of the Place de l'Église, renamed Place du Général Leclerc.
