Answer in one word:

What do you know about the Black Hole Tragedy?

During the battle of Plassey, the English became the cause of trouble for Siraj-ud-daulah, the Nawab of Bengal. When the Nawab of Bengal asked the Britishers not to strengthen their fortification in Bengal, they refused to do so. Also, the Britishers were misusing the power given to them for doing trade in India. This made Nawab angry, and he captured Calcutta along with his army. He locked 146 British soldiers in a small room. Except 23, all of them died due to suffocation. This incident came to be known as the black hole tragedy.
