My mother took the train to Halifax to see my father off. It was crammed with men en route to the Front; she could not get a sleeper, so she travelled sitting up. There were feet in the aisles, and bundles, and spittoons; coughing, snoring - drunken snoring, no doubt. As she looked at the boyish faces around her, the war became real to her, not as an idea but as a physical presence.
