Battle Of Plassey 1757

Battle Of Plassey 1757


  • The Battle of Plassey became famous because it was the first major victory the Company won in India.
  • The Battle of Plassey was a decisive victory of the British East India Company over the Nawab of Bengal Siraj-ud-daula and his French allies on 23 June 1757, under the leadership of Robert Clive.
  • The war is often known for the ‘great betrayal’ to the Nawab due to the defection of Mir Jafar Ali Khan, who was Siraj-ud-daulah’s commander in chief.
  • The battle took place at Plassey on the banks of the Hooghly River, about 150 kilometres north of Calcutta and south of Murshidabad, then capital of Bengal.

Causes of the Battle of Plassey

Majorly the reasons for the Battle of Plassey to take place were:

  • Non-payment of tax and duty by the workers of the British East India Company
  • The rampant misuse of the trade privileges given to British by the Nawab of Bengal

Other reasons that supported the coming of this battle were:

  • Misleading Nawab on various fronts by British
  • Fortification of Calcutta by British without Nawab’s permission
  • An asylum was provided to Nawab’s fugitive Krishna Das


  • The East India Company had a strong presence in India majorly at Fort St. George, Fort William, and Bombay Castle.
  • The British resorted to having an alliance with the Nawabs and princes in exchange for security against any form of external and internal attack and were promised concessions in return for their safety and protection.
  • The problem arose when the alliance was disrupted under the rule of Nawab of Bengal (Siraj-Ud-Daulah). The Nawab started seizing the fort of Calcutta and imprisoning many British Officials in June 1756. The prisoners were kept in a dungeon in Fort William. This incident is called the Black Hole of Calcutta since only a handful of the prisoners survived the captivity where over a hundred people were kept in a cell meant for about 6 people. The East India company planned an attack and Robert Clive bribed Mir Jafar, the commander-in-chief of the Nawab’s army, and also promised him to make him Nawab of Bengal.
  • The Battle of Plassey was fought at Palashi, on the banks of Bhagirathi river near Calcutta on June 23, 1757.
  • After three hours of intense fighting, there was a heavy downpour. The major reason for the defeat of Nawab was the lack of planning to protect their weapons during the heavy downpour which turned the table in favour of the British army.
  • Siraj-Ud-Daulah’s army with 50,000 soldiers, 40 cannons and 10 war elephants was defeated by 3,000 soldiers of Robert Clive. The battle ended in 11 hours and Siraj-Ud-Daulah fled from the battle post his defeat.
  • According to Robert Clive, 22 men died and 50 were injured from the British troops. The Nawab army lost about 500 men, including several key officials and many of them even suffered several casualties.
