The horrors of trench warfare in WWI are effectively shown in this anti-war drama, in which there were two scenes that stuck with me for hours afterwards. In one, the mournful wails and moans of an injured soldier stuck on barbed wire 100 feet from the trench had dead would-be rescuers strewn about him. The enemy snipers purposely let him live to tempt his fellow soldiers to a rescue so they could kill them. In the other scene, soldiers in a bunker hear the enemy below them and realize they are digging into the area to place explosives to blow it up, and this sets off a panic. Director Howard Hawks paces the film well and has exceptionally good action scenes. There's also a love triangle between Capt. Warner Baxter and his subordinate, Lt. Fredric March (both excellent in their roles) for lovely June Lang, which was an essential part of the plot. I enjoyed the humor provided by Gregory Ratoff and seeing Lionel Barrymore in one of his last films he made without a wheelchair.
