Australian troops liberated the village on 4 September 1918.

To the left of the entrance to the village stands a statue of Field Marshall Ferdinand Foch, which was inaugurated in the presence of the Allied commander. The statue was funded by Wallem Haackon, a wealthy Norwegian industrialist, and a plaque on the local school commemorates this gesture with a portrait of the donor. Haackon's native town, Bergen, also contributed money to the reconstruction of Bouchavesnes, and after 1918 the village added Bergen to its name. This episode attests to the solidarity of foreign countries, who sponsored small towns that had been devastated by the war.
