Editor’s Note : Battle of Plassey paved the way for British entry into India. The erstwhile traders who have been trying to find a political toe hold in the country, found an opportunity when they defeated a vastly superior army of Siraj ud Daulah, the Nawab of Bengal at the battle at Plassey near Murshidabad. Almost everything went wrong on that fateful day of 23 June 1757 for Siraj- ud- Daulah. While the defeat of Siraj ud Daulah’s forces is generally attributed to treachery of  Mir Jafar, there was something more important which lead to the defeat. Siraj Ud Daulah had amassed a army of 50,000 solders against the British forces numbering 3000. If we take into account the 16000 troops under Mir Jafar’s command which did not join the fight, still Siraj ud Daulah had an effective fighting strength of  34000 men and cavalry which far surpassed the British numerical strength at Plassey. Siraj had under his command 57 pieces of heavy field artillery manned by highly trained French troops. In comparison British had 10 artillery pieces. Still Siraj lost,  paving the way for nemesis of Bengal and India.  The write-up recounts the trail of events which lead to this disastrous loss.

There is a famous English adage ‚ÄúKeep your (Gun) powder dry‚ÄĚ, and there could be no better example of this than at the Battle of Plassey. The emperor of Bengal Siraj-ud-Daulah learnt it the hard way when he met the British, lead by Robert Clive, in the battle field at Plassey at the outskirts of Murshidabad town in Bengal on 23 June 1757. The Nawab‚Äôs numerically and technologically superior troops were decisively defeated not because of any extraordinary valour by the British troops, but because it had rained heavily on that day and Siraj -ud-Daulah‚Äôs army had nothing to protect the gunpowder from getting drenched. The Biritsh had the foresight to bring along tarpaulin sheets to drape on their ammunition and guns to prevent them from getting wet. As if this misfortune was not enough, a large section of Siraj‚Äôs troop lead by Mir Jaffar defected to the British side. Siraj- ud- Daulah had lost the battle even before the first bullet was effectively fired.

Battle of Plassey was not another of the multitude battles fought in the Indian sub continent. This battle opened the gates of India to the British and from being traders they became rulers. Tragically though if one were to write a book on Sirajud-Daulah‚Äôs military strategy at Plassey it would be titled ‚ÄúWhat not to do at the battlefield‚ÄĚ. About 500 years ago, at the first battle of Panipat, Babar‚Äôs cannons had disseminated Ibrahim Lodhi‚Äôs army and Mughals came to power in India. Ironically exactly 181 years later, Siraj‚Äďud-Daulah‚Äôs canons refused to fire, which brought in the British as political masters of India.

The British had tried long and hard to find a foot hold in India. English could not make any headway, as Portuguese were sitting pretty in India. They were close to the Mughals and had virtual monopoly on Indian trade. It was only in 1612 that Captain Thomas Best as commander of the 9th British expedition to India reached Surat, the Mughal Trading port in 1612 and achieved a daring naval victory over the Portuguese at the Battle of Swally (15 kms from Surat) . The Mughal Governor allowed British to set up a trading post at Swally. Mughals saw in British a partner to offset the Portuguese influence and monopoly. The bargain however went terribly wrong as later events would unfold. What started with the Battle of Swally in 1612 was completed with the Battle of Plassey in 1757. The traders after Swally became the rulers after Plassey. It had taken British a long 144 years to achieve this. Many events happened in the intervening period, too numerous to be related to here. Let’s concentrate on what happened at Plassey.

The run-up to the Battle of Plassey and its eventual fate is attributable to factors which started much before the first cannon boomed at the mango grove on June 1757 at Plassey. Siraj-ud-Daulah assumed the throne of Bengal from his grandfather Alivardi Khan in 1756 at the age of 23. Statecraft is about juggling with compromises and walking the tightrope. However for a young man suddenly elevated as the king, a few hasty decisions are expected, and Siraj was no exception. He started to purge the system and put in place men he trusted, and naturally he earned a number of enemies, who ultimately would prove to be Siraj’s nemesis. His haughty demeanour and his glad eye for the woman of aristocratic families added to his enemies, who waited for an opportune time to strike back.

That opportunity presented itself when the battle of Plassey happened. Notwithstanding shades of grey in Siraj‚Äôs personality, he has to be given the credit of having foreseen the expansionist intent of the British. When the British started expanding their fortification at Fort William in Calcutta, Siraj objected saying that British were mere traders and had no sovereign rights and that all political powers rested with the Nawab of Bengal. Siraj‚Äôs warning went unheeded by the 34 year old Richard Drake, the then British Commander of Fort. William at Calcutta. In retaliation Siraj attacked Calcutta with a 50,000 strong army. Drake‚Äės arrogance was not backed with military might, the fort was overrun by Raja Durlabh, Siraj‚Äôs General on 20 June 1756. Calcutta was renamed Alinagar. This was the first time Indians had captured a British fortification.

However the victory was marred by the infamous Black Hole of Calcutta incident, which many historians believe lead to the Plassey battle. Siraj’s Army had captured 146 prisoners of war at Fort William and confined them in a small guard room overnight. In the morning it was found that 123 prisoners had died due to suffocation. There are however reports that the figures are exaggerated, but there is a consensus that the event happened. In all probability Siraj was not culpable for this incident, the lower officials of his army were to be blamed. But whatever the cause, the incident raised a furore in Britain. In an unprecedented move, Britain requisitioned all its resources in India, to launch an attack on Siraj ud Daulah. It is possible that had Black Hole incident not happened, the British reaction might have been more cautious and circumspect. The military action over diplomatic means was fuelled with revenge.

British moved in troops and ships to Calcutta from its fortification at Fort St George in Madras. The mobilisation was under the
command of their best military commander Robert Clive. As a dismal lesson in military strategy, Siraj had lightly garrisoned Calcutta,
and Clive with comparative ease recaptured Calcutta. The quick and severity of British response unnerved Siraj, who surrendered,
and promised to compensate the British. Siraj lost his opportunity at Calcutta to stem the British tide. The outcome at Plassey was mirrored in Siraj’s meek capitulation at Calcutta.

Emboldened British pursued for political ascendancy. Robert Clive attacked the French Colony at Chandranagore, near Calcutta. Siraj sided with the French, which brought him again in direct conflict with the British and gave an excuse to the British to press for Siraj’s removal. The moment of truth was fast approaching when on 21 June 1957 Clive arrived at Plassey, located on the outskirts of Siraj-ud-Daulah’s capital at Murshidabad, with an army of 1,100 Europeans and 2,100 Indian sepoys and nine field cannons. Siraj lined up an impressive army with 18,000 cavalry, 35,000 infantry and 53 pieces of heavy ordinance. He also had amongst his ranks French artillerymen lead by St. Frais.

For once in his career Clive hesitated, and called a council of sixteen officers to decide, as he put it, “whether in our present situation, without assistance, and on our own bottom, it would be prudent to attack the Nawab, or whether we should wait till joined by some country (Indian) power.” Clive himself headed the nine who voted for delay; Major Eyre Coote led the seven who counselled immediate attack.

While Siraj ud Daulah had military superiority in terms of soldiers and military hardware, what was lacking was foresight, military logistics, leadership and strategy

Battle of Plassey almost would not have happened but for the receipt of a letter from Mir Jafar one of the Commander of Siraj’s army, who offered to betray his king in lieu of being made the Nawab of Bengal. Siraj have never trusted Mir Jaffer, and had even demoted him from the post of the paymaster of the army. However it is a comment on Siraj’s inexperience that he left the command of 16000 of his troops under Mir Jaffer. The same 16000 troops were to desert the battlefield.

On 23 June around 8 am the French artillery opened fire, followed by Siraj’s cannons. The British responded with their own field guns. In first half an hour the English casualties were heavy, ten European and twenty Indian sepoys from Clive’s unit lay dead. The British infantry retreated into their entrenchment. The first round of the battle had gone to Siraj.

The artillery exchange continued for several hours, it was anybody’s battle. Suddenly a heavy downpour started which drenched most of the Siraj’s gunpowder. As a bad lesson in military logistics, Siraj’s army had forgotten to bring in tarpaulin sheets to keep the guns and powder dry. Resultantly the Indian artillery now became sporadic. However the British continued as before, their powder and ammunition having been covered with tarpaulins was usable. Siraj was now a worried man, his artillery was dysfunctional.

Mir Mardan the most trusted of Siraj’s Generals lead a cavalry charge to overrun the British position. This proved suicidal, the British field guns stemmed the attack and Mir Mardan was killed. The battle had now decisively tilted towards the British. Unlike Clive,  Siraj was not leading from the front, and preferred to sit in his camp hoping for an easy victory. On hearing the death of Mir Mardan, Siraj panicked. He ordered his troops to withdraw behind a protective embankment and he himself left the battle field for his capital at Murshidabad 48 kms away, leaving the battle to his generals. Seeing their king leave the battlefield, the morale of the troops plummeted.

It was now 2 PM, the French artillery of 4 guns kept up the fire. As predetermined, Mir Jafar betrayed Siraj and his 16000 men moved away from the battlefield. The French, who were putting up a brave resistance, had banked on Mir Jafar’s men for support, were now stranded and got over powered by the British. Of all the Siraj’s troops, the French were last to retreat from the battlefield. British finished off the battle with cannon fire at Siraj’s camped troops. By 4.30 PM British victory was complete. The total losses suffered by British were 22 killed and 50 wounded. Siraj lost about 500 men.

Mir Jafar was made the Nawab, a reward for his treachery. Siraj ud Daulah fled from Murshidabad. Enroute on his way to Patna, he took refuge for the night at a deserted garden at Rajmahal where he was detected and eventually murdered on orders of Mir Jaffer’s son Miran. Ironically untimely death awaited the victor of Plassey as well; Robert Clive committed suicide 16 years later in 1774 at the age of 49 in London, due to long term depression and debilitating disease. And as for Mir Jafar, history has not forgiven him for his treachery. Till date the palace of Mir Jafar in Murshidabad is known as Namak Haram Deorhi (Traitor’s Gate).

None of the sides came out with any glory from the battle. British won through treachery, while Siraj made elementary mistakes in military strategy. And God was not on Indian side for sending in untimely rain that afternoon.
