Winston Churchill was born into a famous family．His father was a successful politician．However, as a boy, Churchill was considered a slow learner in school．Later he entered the Army and saw action in various countries．

In October 1900, Churchill began his political career．For the next sixty years Churchill’s work as a great politician was both brighter and more difficult than his father’s had been．In 1939 German attacked Poland．Churchill prepared to fight．In 1940 he became the Prime Minister of English．

France fell．The Germans fought their way through Western Europe．It looked as if Britain was about to lose the war．Was it now possible to ask for peace, and listen to Hitler?

Churchill spoke: “I have nothing to offer but blood, hard work , tears and sweat… You ask what is our policy? I will tell you, it is to fight, by sea , by land and air, with all our force and with all the strength that God can give us．You ask what is our aim? I can answer in one word: Victory．”

The Germans began moving their armies to the French coast and prepared to go to war with British．The British had not enough guns to go around．Churchill gave the answer: “ We shall defend our island, whatever the cost may be．We shall fight on the coast ; we shall fight on the landing grounds; we shall fight in the fields and in the streets; we shall fight in the hills; we shall never give up．”

By his courage and hard work, Churchill heartened his people and other nations fighting together against Hitler．Victory finally came when the Germans lost World War II．

Churchill died in 1965 and was given a state funeral．This was a fitting payment to one of all the greatest men the world had ever seen．
