Mangal Pandey, a young soldier, was hanged to death for attacking his officers in Barrackpore.

Explanation:
Mangal Pandey was a soldier in the British East India Company's army during the mid-19th century. He is known for his role in the Indian Rebellion of 1857, which was a significant event in the fight against British colonial rule in India.

The incident that led to Mangal Pandey's execution was his attack on his officers in Barrackpore. The exact details of the event vary in different accounts, but it is generally agreed that on March 29, 1857, Pandey confronted and attacked his British officers, including Lieutenant Baugh, who was the Adjutant of the 34th Bengal Native Infantry.

Mangal Pandey's attack on his officers was a result of several factors. He was deeply affected by the introduction of the new Enfield rifle cartridges, which were rumored to be greased with animal fat (cow and pig fat) that had to be bitten off before loading the rifle. This was offensive to both Hindu and Muslim soldiers, as the consumption of beef and pork was against their religious beliefs. Pandey saw this as a deliberate attempt by the British to undermine Indian culture and religion.

Pandey's attack on his officers sparked a larger rebellion among the Indian soldiers in the Barrackpore cantonment. This event is often considered as the beginning of the wider Indian Rebellion of 1857, which spread to other parts of India.

Mangal Pandey was arrested and put on trial for his actions. He was found guilty of mutiny and sentenced to death by hanging. On April 8, 1857, he was executed in Barrackpore.

This event, along with the wider rebellion, had a significant impact on the Indian independence movement. Mangal Pandey became a symbol of resistance against British oppression, and his actions inspired other freedom fighters in their struggle for independence.

In conclusion, Mangal Pandey was hanged to death for attacking his officers in Barrackpore. His actions played a crucial role in the Indian Rebellion of 1857 and became a symbol of resistance against British colonial rule in India.
