Memories
In September,1940, my mother, sister and I went to Swansea, where my father's ship wasgetting ready to sail. We brought him a family photograph to be kept with him at all times and keephim safe.
Then I remember my mother lying face down, sobbing. She had heard from a friend that theship had been sunk by a torpedo(鱼雷).
I can remember the arrival of the telegram ( 电报 ), which in those days always brought badnews. My grandmother opened it. It read, "Safe. Love Ted."
My most vivid memory is being woken and brought down to sit on my father's knee, his armin a bandage.
He was judged unfit to return to sea and took a shore job in Glasgow for the rest of the war.
For as long as I can remember, he had a weak heart. Mother said it was caused by the torpedoes.
He said it was because of the cigarettes, whichever, he died suddenly in his early 50s.
Ten years later I read Night of the U-bouts and was able to complete the story.
Torpedo One torpedo struck the ship; Father was in the engine room, where the third engineer waskilled. He shut down the engines to slow the ship making it easier for it to be abandoned.
By the time he got on desk (甲板) he was alone. Every lifeboat was gone except one whichhad stuck fast. When he tried to cut it free, it swung against the ship, injuring his hand and arm.
He had no choice but to jump--still with the photograph in his pocket.
Three days later, he and other survivors were safe in Glasgow. All 23 with him signed theback of the photograph.
A Toast
In my room is the book and the photograph. Often, glass in hand; I have wondered how Iwould have dealt with an explosion, a sinking ship, a jump into a vast ocean and a wait for rescue?
Lest(以免)we forget, I have some more whisky and toast the heroes of the war.
