August 15 is a memorable day in the history of India. It was on August 15, 1947, that India won her independence after a long and bitter struggle. At the stroke of midnight, Jawaharlal Nehru read out his “Tryst with destiny” speech, proclaiming India's independence. He became the first Prime Minister of Independent India. Today, as befitting the day, there are celebrations all over the nation with the national flag being hoisted. From the ramparts of the Red Fort in New Delhi, the Prime Minister delivers his message to the nation.
