Siraj ud Daulah: Battle of Plassey on 23rd June 1757 in the Anglo-French Wars in India: picture by Richard Caton Woodville:

Bengals s army comprised 35,000 infantry, 15,000 cavalry and 53 pieces of cannon, being 18, 24 and 32 pounders. A small French force commanded by St Frais provided supervision for the artillery and manned some guns. 

where Clive’s army at Plassey comprised 950 European Troops (including 250 men of His Majesty’s 39th Foot), 2,100 native troops being sepoys and topazes, 60 sailors and 100 artillerymen, with eight 6 pounder guns and two howitzers.

The British, worried about being outnumbered, formed a conspiracy with Siraj-ud-Daulah's demoted army chief Mir Jafar, along with others such as Yar Lutuf Khan, Jagat Seths (Mahtab Chand and Swarup Chand), Omichund and Rai Durlabh. Mir Jafar, Rai Durlabh and Yar Lutuf Khan thus assembled their troops near the battlefield but made no move to actually join the battle . 

The British Diplomacy of Bribing : 

This action on Clive’s part infuriated Siraj-ud-Daulah. He was just twenty years of age. English descriptions of Siraj-ud-Daulah give him as inexperienced, in contrast to his adversary Clive, a  ruthless soldier and Plotter  In addition Siraj-ud-Daulah’s realm was constantly threatened with invasion on its western border by the Afghans and the Mahrattas, diverting his resources and attention from his problems with the English in the east.

Clive had many years experience of manipulating the native leaders against whom he was pitted. From his arrival in Bengal, Clive worked to corrupt Siraj-ud-Daulah’s generals and courtiers. As further war became imminent, with the destruction of Chandranagar, Siraj-ud-Daulah could rely fully on only a small number of his senior commanders, with many of the major interests in his capital, Murshidabad, committed to the English.

During this time Clive negotiated a treaty, through the intermediary William Watts, with Mir Jafar Khan, whereby the English would assist Mir Jafar Khan in obtaining the Nawabship of Bengal, Bihar and Orissa, in exchange for substantial payments to the Company and its various officers. Many of Siraj-ud-Daulah’s senior officers were in support of Mir Jafar Khan in this conspiracy. Under the treaty Mir Jafar Khan undertook to change sides during any hostilities.

Battle

A large stage, raised six feet from the ground, carrying besides the cannon, all the ammunition belonging to it, and the gunners themselves who managed the cannon, on the stage itself. These machines were drawn by 40 or 50 yoke of white oxen, of the largest size, bred in the country of Purnea; and behind each cannon walked an elephant, trained to assist at difficult tugs, by shoving with his forehead against the hinder part of the carriage.

At daybreak on 23 June, the Nawab's army emerged from their camp and started advancing towards the grove. Their army consisted of 30,000 infantry of all sorts, armed with matchlocks, swords, pikes and rockets and 20,000 cavalry, armed with swords or long spears, interspersed by 300 pieces of artillery, mostly 32, 24 and 18-pounders. The army also included a detachment of about 50 French artillerymen under de St. Frais directing their own field pieces. The French took up positions at the larger tank with four light pieces advanced by two larger pieces, within a mile of the grove. Behind them were a body of 5,000 cavalry and 7,000 infantry commanded by the Nawab's faithful general Mir madan Khan and Diwan Mohanlal. 

The rest of the army numbering 45,000 formed an arc from the small hill to a position 800 yards (730 m) east of the southern angle of the grove, threatening to surround Clive's relatively smaller army. The right arm of their army was commanded by Rai Durlabh, the centre by Yar Lutuf Khan and the left arm closest to the British by Mir Jafar.

Clive watched the situation unfolding from the roof of the hunting lodge, anticipating news from Mir Jafar. He ordered his troops to advance from the grove and line up facing the larger tank. His army consisted of 750 European infantry with 100 Topasses, 2100 sepoys (dusadhs) and 100 artillery-men assisted by 50 sailors. The artillery consisted of eight 6-pounders and two howitzers. The Europeans and Topasses were placed in the centre of the line in four divisions, flanked on both sides by three 6-pounders. The sepoys were placed on the right and left in equal divisions. Clive posted two 6-pounders and two howitzers behind some brick-kilns 200 yards (180 m) north of the left division of his army to oppose the French fire.

Battle begins

At 8:00, the French artillery at the larger tank fired the first shot, killing one and wounding another from the grenadier company of the 39th Regiment. This, as a signal, the rest of the Nawab's artillery started a heavy and continuous fire. The advanced field pieces of the British opposed the French fire, while those with the battalion opposed the rest of the Nawab's artillery. Their shots did not serve to immobilize the artillery but hit the infantry and cavalry divisions. By 8:30, the British had lost 10 Europeans and 20 sepoys. Leaving the advanced artillery at the brick kilns, Clive ordered the army to retreat back to relative shelter of the grove. The rate of casualties of the British dropped substantially due to the protection of the embankment.

At the end of three hours, there was no substantial progress and the positions of both sides had not changed. Clive called a meeting of his staff to discuss the way ahead. It was concluded that the present position would be maintained till after nightfall, and an attack on the Nawab's camp should be attempted at midnight. Soon after the conference, a heavy rainstorm occurred. The British used tarpaulins to protect their ammunition, while the Nawab's army took no such precautions. As a result, their gunpowder got drenched and their rate of fire slackened, while Clive's artillery kept up a continuous fire. As the rain began to subside, Mir Madan Khan, assuming that the British guns were rendered ineffective by the rain, led his cavalry to a charge. However, the British countered the charge with heavy grape shot, mortally wounding Mir Madan Khan and driving back his men.

Siraj had remained in his tent throughout the cannonade surrounded by attendants and officers assuring him of victory. When he heard that Mir Madan was mortally wounded, he was deeply disturbed and attempted reconciliation with Mir Jafar, flinging his turban to the ground, entreating him to defend it. Mir Jafar promised his services but immediately sent word of this encounter to Clive, urging him to push forward. Following Mir Jafar's exit from the Nawab's tent, Rai Durlabh urged Siraj to withdraw his army behind the entrenchment and advised him to return to Murshidabad leaving the battle to his generals. Although trusted commander Mohan Lal pursued him not to retreat the troops, that would be fetal but Siraj complied with this advice of Mir Jafar and Rai Durlav. Subsequently ordered the troops under Mohan Lal to retreat behind the entrenchment. He then mounted a camel and accompanied by 2,000 horsemen set out for Murshidabad.^{[91][92][93][94]}

Battlefield manoeuvres

At about 14:00, the Nawab's army ceased the cannonade and began turning back north to their entrenchments, leaving St. Frais and his artillery without support. Seeing the Nawab's forces retiring, Major Kilpatrick, who had been left in charge of the British force while Clive was resting in the hunting lodge, recognised the opportunity to cannonade the retiring enemy if St. Frais' position could be captured. Sending an officer to Clive to explain his actions, he took two companies of the 39th Regiment and two field pieces and advanced towards St. Frais' position. When Clive received the message, he hurried to the detachment and reprimanded Kilpatrick for his actions without orders and commanded to bring up the rest of the army from the grove. Clive himself then led the army against St. Frais' position which was taken at 15:00 when the French artillery retreated to the redoubt of the entrenchment, setting up for further action.

As the British force moved towards the larger tank, it was observed that the left arm of the Nawab's army had lingered behind the rest. When the rear of this division reached a point in a line with the northern point of the grove, it turned left and marched towards the grove. Clive, unaware that it was Mir Jafar's division, supposed that his baggage and stores were the intended target and sent three platoons under Captain Grant and Lieutenant Rumbold and a field piece under John Johnstone, a volunteer, to check their advance. The fire of the field piece halted the advance of the division, which remained isolated from the rest of the Nawab's army.

Meanwhile, the British field pieces began a cannonade on the Nawab's camp from the mound of the larger tank. As a result, many of the Nawab's troops and artillery started coming out of the entrenchment. Clive advanced half of his troops and artillery to the smaller tank and the other half to a rising ground 200 yards (180 m) to the left of it and started bombarding the entrenchment with greater efficiency, throwing the approaching trains into confusion. The Nawab's troops shot their matchlocks from holes, ditches, hollows and from bushes on the hill east of the redoubt while St. Frais kept up his artillery fire from the redoubt. Cavalry charges were also repulsed by the British field pieces. However, the British force sustained most of its casualties in this phase.

At this point, Clive realised that the lingering division was Mir Jafar's and concentrated his efforts at capturing the redoubt and hill east of it. Clive ordered a three-pronged attack with simultaneous attacks by two detachments on the redoubt and the hill supported by the main force in the centre. Two companies of grenadiers of the 39th Regiment, under Major Coote took the hill at 16:30 after the enemy fled without firing a shot. Coote pursued them across the entrenchment. The redoubt was also taken after St. Frais was forced to retreat. By 17:00, the British occupied the entrenchment and the camp left by a dispersing army. The British troops marched on and halted 6 miles (9.7 km) beyond Daudpur at 20:00.

The British losses were estimated at 22 killed and 50 wounded. Of the killed, three were of the Madras Artillery, one of the Madras Regiment and one of the Bengal European Regiment. Of the wounded, four were of the 39th Regiment, three of the Madras Regiment, four of the Madras Artillery, two of the Bengal European Regiment, one of the Bengal Artillery and one of the Bombay Regiment. Of the losses by the sepoys, four Madras and nine Bengal sepoys were killed while nineteen Madras and eleven Bengal sepoys were wounded. Clive estimates that the Nawab's force lost 500 men, including several key officers.

Aftermath

In the evening of 23 June, Clive received a letter from Mir Jafar asking for a meeting with him. Clive replied that he would meet Mir Jafar at Daudpur the next morning. When Mir Jafar arrived at the British camp at Daudpur in the morning, Clive embraced him and saluted him as the Nawab of Bengal, Bihar and Odisha. He then advised Mir Jafar to hasten to Murshidabad to prevent Siraj's escape and the plunder of his treasure. Mir Jafar reached Murshidabad with his troops on the evening of 24 June. Clive arrived at Murshidabad on 29 June with a guard of 200 European soldiers and 300 sepoys in the wake of rumours of a possible attempt on his life. Clive was taken to the Nawab's palace, where he was received by Mir Jafar and his officers. Clive placed Mir Jafar on the throne and acknowledging his position as Nawab, presented him with a plate of gold rupees.^[108][109]

Siraj-ud-daulah had reached Murshidabad at midnight on 23 June. He summoned a council where some advised him to surrender to the British, some to continue the war and some to prolong his flight. At 22:00 on 24 June, Siraj disguised himself and escaped northwards on a boat with his wife and valuable jewels. His intention was to escape to Patna with aid from Jean Law. At midnight on 24 June, Mir Jafar sent several parties in pursuit of Siraj. On 2 July, Siraj reached Rajmahal and took shelter in a deserted garden but was soon discovered and betrayed to the local military governor, the brother of Mir Jafar, by a man who was previously arrested and punished by Siraj. His fate could not be decided by a council headed by Mir Jafar and was handed over to Mir Jafar's son, Miran, who had Siraj murdered that night. His remains were paraded on the streets of Murshidabad the next morning and were buried at the tomb of Alivardi Khan.

According to the treaty drawn between the British and Mir Jafar, the British acquired all the land within the Maratha Ditch and 600 yards (550 m) beyond it and the zamindari of all the land between Calcutta and the sea. Besides confirming the firman of 1717, the treaty also required the restitution, including donations to the navy squadron, army and committee, of 22,000,000 rupees (£2,750,000) to the British for their losses. However, since the wealth of Siraj-ud-daulah proved to be far less than expected, a council held with the Seths and Rai Durlabh on 29 June decided that one half of the amount was to be paid immediately – two-thirds in coin and one third in jewels and other valuables. As the council ended, it was revealed to Omichund that he would receive nothing with regard to the treaty, hearing which he went insane .
