Every year all Americans celebrate Thanksgiving Day. The story started in 1620, A group of people decided to leave England and go to live in America. They wanted to be free to practise their religion. And they wanted a new and better life. On 16th September 1620 they left Plymouth, a port on the south coast of England. Their ship was called "the Mayflower". There were about a hundred of diem. They took their animals with them; pigs, goats and chickens. It took them about a month or two to cross the Atlantic Ocean, Don't forget, there were no engines in those ships — only sails and the wind. At last they saw America on the 9th November. Some people didn't Jive to see America. They had become sick and died before they arrived in America.
The first winter in America was very hard for the travellers, the Pilgrims as they were called.
The Indians helped the Pilgrims. They were shown how to hunt, fish and grow corn. The next year the Pilgrims had a lot of food.
The Pilgrim fathers built the town Plymouth. And they thanked God for their new home. It was almost four hundred years ago. And every year on the fourth Thursday in November American families get together and celebrate Thanksgiving Day. The traditional food on this day is turkey and pumpkin pie.
