The Death Trench was provided with an alternative straight communication line. A light wooden railway track was layed, to enable transport and evacuation by means of the small trucks. Numerous “concrete-brick” shelters were created. Finally the head of the trench was turned into a deathtrap, surrounded by wolf’s holes and barbed wires, that point was only manned by day time by snipers sheltered in a small concrete sentry box. The trap was separated from the death trench by a monolithe concrete dug-out of a rather peculiar shape. That shelter was fitted with a heavy steel door, and loopholed to enable hand grenade throwing and automatic rifle’s firing. A vibrating connected the little redoubt with the Commander of the “Cavalier”. In case that the enemy managed to enter the trap or to reach our trench, the garrison of the fortlet was to shut itself up in it and resist from within during a length of time sufficient to be relieved by a counter-attack delivered by the “Cavalier” which had been alerted by the buzzer. During the Franco-British offensive of October 1917 numerous fires were carried out by our artillery to prepare the eventual cooperation of the Belgian forces. That artillery action brought on to us energetic retaliations which did a lot of damages to the line at Roode-Poort. The numerous raids of our troops in the German lines proved the efficiency of our fire, which had reduced the enemy’s trenches to mere ruins. When the 1917 offensive was stopped the life resumed its normal and dull course; the 5^{th} infantry division was set at work to repair the damages and restore to our positions their former power. Our attack of September 1918 had a repercussion upon the whole sector overlooked by the Cavalier. The first battle had brought the Belgian Army on the Clercken ridge. The intention to hinge the new front to the old one including the Dixmude town, induced the 5^{th} line Regiment to get hold of Trench “One”, “111”, as well as of the first work North of Dixmude. And this was to be the only alteration brought on the front round kilometer 16. From the 15^{th} to the 17^{th} of October, under the victorious onrush of the second battle, the front was split up from Nieuport to Dixmude and the Germans were compelled to a hurried retreat. The front of the Yser was definitively cleared, the Rider and the Death Trench had ended their glorious mission. It is important to note the powerful organizations of the enemy, facing the “Death Trench”, notably the enormous concrete of German sap-heads on the leftbank of the Yser, with their iron-plated loopholes and firing ranges, overlooking all the surrounding districts.
