On a beautiful afternoon, in a year long gone, a big ship set out on its first voyage from England to America. It was a new ship called the “Titanic”.
For two days the “Titanic” went on its way over the sea. Then entered an ice-field and was hit by an iceberg.
Everyone was told to come out of their rooms. The men were putting the lifeboats over the sides of the ship down into the water. Then all the women and children were helped into the lifeboats.
A woman came to the side of the ship. Her two children were in oil, of the lifeboats, and she was very much afraid.
“My children are in the lifeboat. I must go with them!” the woman called to the people in the lifeboat.
“There's no more room,” someone called out. “If we take one more the lifeboat will sink.”
There was a young woman in the lifeboat called Miss Evans. When she heard the woman calling, she stood up in the lifeboat and touched one of the men on the arm.
“Let me get back on to the ship,” she said. “Let that woman take my place. I have no children.”
“The ship is sinking,” said the man. “You know that?”
There was no time to talk. People helped Miss Evans to get back on to the ship. Very soon after that there was a great noise, and the “Titanic” went down under the water.
