The battle that barely was

It lasted a few hours. One side had 50,000 men, the other about 3,000. The smaller side won — because most of the bigger army had already agreed not to fight.

The Battle of Plassey, fought on 23 June 1757, is the single most important battle in modern Indian history. Not because of the fighting — there was very little — but because of what followed. After Plassey, the East India Company stopped being just a trader and became the real power in Bengal, the richest province in India. Everything that came afterwards, right up to 1947, grows out of this one afternoon near a village called Palashi.

KEY TERM
Where and who

Where: near the village of Plassey (Palashi), on the bank of the Bhagirathi river, in present-day West Bengal. The British side: the East India Company, led by Robert Clive. The Indian side: Siraj-ud-Daulah, the young Nawab of Bengal, who had become Nawab only the previous year after his grandfather Alivardi Khan died.

Why the fight happened

The quarrel had been building for years, and it was mostly about money and disrespect.

CauseWhat it meant
Misuse of dastaksIn 1717 the Mughal emperor Farrukhsiyar gave the Company a farman — a royal order — allowing duty-free trade in Bengal, using passes called dastaks. Company officials began misusing these passes for their private trade, and even selling them to Indian merchants. The Nawab lost a large part of his customs revenue
Fortifying CalcuttaThe English strengthened the defences of Fort William at Calcutta without the Nawab's permission — in his eyes, a foreign trader building a fortress inside his own kingdom
Shelter to a fugitiveThe Company gave protection to Krishna Das, who had fled with treasure against the Nawab's wishes — a direct insult to the Nawab's authority
The Nawab's youthSiraj-ud-Daulah was young and newly installed, and several of his own nobles resented him — which the British would later use

The road to the battle

June 1756
Siraj captures Calcutta

Angered by the fortification, the Nawab marched on Calcutta and took Fort William. It is here that the alleged Black Hole of Calcutta incident is said to have occurred, when British prisoners were reportedly held overnight in a small room and many died.

January 1757
Clive retakes Calcutta

Robert Clive arrived from Madras with troops and ships and recaptured the city.

February 1757
Treaty of Alinagar

A peace was patched up. The Nawab restored the Company's trading privileges. But Clive had already decided that peace was not enough.

June 1757
The conspiracy

Clive secretly agreed with Mir Jafar, the Nawab's own commander-in-chief, that Mir Jafar would hold back his troops during the battle — and would be made Nawab in return.

WHY PLASSEY WAS WON BEFORE IT BEGAN

This is the heart of the topic. Clive did not defeat Siraj-ud-Daulah with better soldiers — he defeated him by buying his generals. Mir Jafar, who commanded the largest part of the Nawab's army, simply stood still during the battle with his men. So the Nawab's 50,000 troops were mostly spectators. Only a small loyal force under Mir Madan actually fought, and when Mir Madan was killed by cannon fire, the Nawab's cause collapsed. Plassey is remembered as a victory of conspiracy, not of arms.

QUICK FACT

A famous detail: a heavy monsoon shower fell during the battle. Clive's men covered their gunpowder with tarpaulins; the Nawab's men did not, and their wet powder failed. The Nawab's cavalry charged, believing the British guns would also be silent — and were cut down.

What happened after

Siraj-ud-Daulah fled and was captured, and was killed on the orders of Mir Jafar's son, Miran. Mir Jafar was made Nawab — but only in name.

  • Mir Jafar became a puppet. He owed his throne to the Company and could not refuse it anything
  • The Company received enormous payments — money, land revenue rights around Calcutta, and huge personal presents to Clive and other officials
  • The Company gained a near-monopoly over Bengal's trade, squeezing out Indian and other European merchants
  • Clive became immensely rich, and was later questioned in Britain over the fortune he had made
PLASSEY VERSUS BUXAR — DO NOT CONFUSE THEM

Both are asked constantly, often in the same question. Plassey (1757) made the Company the real power behind the throne in Bengal — but the Nawab was still, on paper, the ruler. Buxar (1764) was a genuine military victory over a combined army of three powers, and it led to the Diwani of 1765, which made the Company the legal tax collector of Bengal, Bihar and Orissa. Plassey won influence; Buxar won legal authority.

CHECK YOURSELF

Why is the Battle of Plassey called a victory of conspiracy rather than of arms?

Because Clive had secretly bought off Mir Jafar, the Nawab's commander-in-chief, who held his troops back during the fighting. Most of the Nawab's 50,000 men never fought, so a force of about 3,000 was able to win.

REMEMBER

Plassey = 1757, Clive, Siraj, Mir Jafar's betrayal, influence won. Buxar = 1764, Munro, three rulers, Diwani won. Two battles, seven years apart, two different kinds of victory.

Frequently Asked Questions

When and where was the Battle of Plassey fought?

On 23 June 1757, near the village of Plassey, also called Palashi, on the bank of the Bhagirathi river in present-day West Bengal. It was fought between the East India Company under Robert Clive and Siraj-ud-Daulah, the Nawab of Bengal.

What were the causes of the Battle of Plassey?

The main causes were the misuse of dastaks, duty-free trade passes granted by the 1717 farman of Emperor Farrukhsiyar, which cost the Nawab his customs revenue; the fortification of Fort William at Calcutta without the Nawab's permission; the Company sheltering the fugitive Krishna Das; and the general resentment between the young Nawab and the Company.

Who betrayed Siraj-ud-Daulah at Plassey?

Mir Jafar, the Nawab's own commander-in-chief, who had secretly agreed with Robert Clive to hold his troops back during the battle in exchange for being made Nawab afterwards. Because he commanded the largest part of the army, most of the Nawab's fifty thousand men never fought.

Why is the Battle of Plassey considered so important?

Because it turned a trading company into a political power. After Plassey the Company controlled the Nawab of Bengal, gained enormous payments and a near-monopoly over Bengal's trade, and took its first real step towards ruling India. Militarily it was a small engagement, but politically it changed everything that followed.

What is the difference between the Battle of Plassey and the Battle of Buxar?

Plassey in 1757 made the Company the real power behind the throne in Bengal, though the Nawab remained the nominal ruler. Buxar in 1764 was a genuine military victory over the combined armies of Mir Qasim, the Nawab of Awadh and the Mughal Emperor, and it led to the Diwani of 1765, which made the Company the legal revenue collector of Bengal, Bihar and Orissa.

What happened to Siraj-ud-Daulah after the battle?

He fled the battlefield, was captured soon after, and was killed on the orders of Miran, the son of Mir Jafar. Mir Jafar was then installed as Nawab, but he owed his throne entirely to the Company and functioned as a puppet ruler.

What role did the weather play in the Battle of Plassey?

A heavy monsoon shower fell during the battle. Clive's men covered their gunpowder with tarpaulins while the Nawab's forces did not, leaving their powder wet and their guns useless. The Nawab's cavalry charged expecting the British guns to be silent too, and were cut down.
