Delphaut created a marble sculpture of a line of four injured soldiers for the Malo-les-Bains World War I memorial. Delphaut received the commission for the work in December 1933.
The war memorial (French: monument aux morts), "distinguished by its size, style, originality and sobriety", shows four wounded soldiers who have returned from the front and are heading for a first aid post. The leading soldier has been blinded. His right hand is held to his eyes and his left hand seems to be feeling for a way forward. The second soldier has been gassed and leans his head on the blinded soldier. Behind him the third man appears on the point of collapse and he is supported by the last of the soldiers who is also wounded and is clearly in a state of great shock. This monument stands in the place Delta in Malo-Les-Bains.
The memorial was inaugurated in June 1935.
