this be an excellent but hard to find trippy world war i spy thriller in the inimitable 60 italian style . from the psychedelic graphic of the introductory credit and the great score by ennio morricone to the lesbian love scene with capucine and the elaborately produce apocalyptic no man land battle scene with poison gas and german cavalry in full gas proof torm trooper gear and this be a movie that should not be miss . it be a film that capture the horror and cruelty of war and the ruthlessness of the player on and off the battlefield . apart from the battle scene and some of the production and special effect be primitive and apparently because the bulk of the budget for this movie be save for the battle scene and but for lover of 60 cinema it should not be an issue . i first saw this movie on television many year ago and have the foresight to tape it on vhs . i still have the tape and enjoy watch it again from time to time .
