Trench. A ditch full of water, rats, and soldiers. During his visit to France, Tommy uses these ditches as residences. Now and again he sticks his head "over the top" to take a look at the surrounding scenery. If he is lucky he lives to tell his mates what he saw.
Trench Feet. A disease of the feet contracted in the trenches from exposure to extreme cold and wet. Tommy's greatest ambition is to contract this disease because it means "Blighty" for him.
Trench Fever. A malady contracted in the trenches; the symptoms are high temperature, bodily pains, and homesickness. Mostly homesickness. A bad case lands Tommy in "Blighty," a slight case lands him back in the trenches, where he tries to get it worse than ever.
"Trenchitis." A combination of "fedupness" and homesickness, experienced by Tommy in the trenches, especially when he receives a letter from a friend in Blighty who is making a fortune working in a munition plant.
Trench Mortar. A gun like a stove pipe which throws shells at the German trenches. Tommy detests these mortars because when they take positions near to him in the trenches, he knows that it is only a matter of minutes before a German Shell with his name and number on it will be knocking at his door.
Trench Pudding. A delectable mess of broken biscuits, condensed milk, jam, and mud. Slightly flavored with smoke. Tommy prepares, cooks, and eats this. Next day he has
"trench fever."
Trench Raid. Several men detailed to go over the top at night and shake hands with the Germans, and, if possible, persuade some of them to be prisoners. At times the raiders would themselves get raided because Fritz refused to shake and adopted nasty methods.
Turpenite. A deadly chemical shell invented by an enthusiastic war correspondent suffering from brain storm. Companies and batteries were supposed to die standing up from its effects, but they refused to do this.
"Twelve in one." Means that twelve men are to share one loaf of bread. When the slicing takes place the war in the dugout makes the European argument look like thirty cents.
