<P> The Battle of Plassey ( or Palashi ) is widely considered the turning point in the history of the subcontinent , and opened the way to eventual British domination . After Siraj - ud - Daulah 's conquest of Calcutta , the British sent fresh troops from Madras to recapture the fort and avenge the attack . A retreating Siraj - ud - Daulah met the British at Plassey . He had to make camp 27 miles away from Murshidabad . On 23 June 1757 Siraj - ud - Daulah called on Mir Jafar because he was saddened by the sudden fall of Mir Mardan who was a very dear companion of Siraj in battles . The Nawab asked for help from Mir Jafar . Mir Jafar advised Siraj to retreat for that day . The Nawab made the blunder in giving the order to stop the fight . Following his command , the soldiers of the Nawab were returning to their camps . At that time , Robert Clive attacked the soldiers with his army . At such a sudden attack , the army of Siraj became indisciplined and could think of no way to fight . So all fled away in such a situation . Betrayed by a conspiracy plotted by Jagat Seth , Mir Jafar , Krishna Chandra , Omichund etc. , he lost the battle and had to escape . He went first to Murshidabad and then to Patna by boat , but was eventually arrested by Mir Jafar 's soldiers . </P>
