To get to know how the massacre of British soldiers and civilians  took place, we have to go back on the earliest phases of East India Company's  trading activities in Bengal in 1700s. The English traders had now turned into land-grabbers  as their eyes were glued on the scope of huge revenue from fertile Bengal, After the  dishonest victory at the battle  Plassey in 1757 against Nawab Siraj-ud-daulah's  army, Robert Clive had established  the British rule in Bengal and left for England  with a big booty on 3 Friary 1760. Henry Vansittart (reign:1759 to 1764) became the chief of Ft. William, Calcutta to look after the company operations. Now armed with ruling powers, the council of the Company confirmed Mir Qasim as the new Nawab of Bengal (reign:1760 to 1763) on 20 October 1760 replacing his father-in-law Nawab Mir Jaffer who became a traitor and  helped the English company defeat Nawab Siraj. Not only that he had Siraj killed  in collusion with the British officials.  The British thought they could use Mir Qasim as a puppet Nawab   who could of great service to the company and get as  much trade concessions as possible. Over a period of time Mir Qasim realized his folly and understood what the wily British were up to. His relationship with the company became soured  because there were many private British traders operating  illegally side by side with EIC, not paying duty/tax and the Nawab's treasury incurred heavy loss. of revenue. 

Mir Qasim moved his court to Munger, Bihar  when Gov. Vansittart met the Nawab and assured him to take suitable action on the private traders who did not pay  tax taxes. At Calcutta the Council members protested to the governor regarding payment of taxes, etc. Further, they argued, the Nawab was only a representative of the Mogul ruler and had no authority over them  or the company as they got the permit from the Mogul king. The council sent two members to Munger to warn Qasim who captured them both. Later Qasim seized a boat laden with arms destined for factory and garrison  at Patna. Negotiations having been failed between the Nawab and the EIC, in June 1763 the British army plundered Patna and attacked the citizens. Nawab's army gave no resistance. 

When Mir Qasim  at Munger was informed about the seizure of Patna by the British, he was furious. Just 15 miles away , Nawab Qasim sent his powerful army to recapture Patna. On 1 July 1763 there took place a big battle at Manjihi and subsequently there were many  skirmishes and numerous killings. Again in October when he heard the British capture of fort in Manger, he was in rage and at that time English officials like Fullerton, Hay, Ellis were in Qasim army's custody in the house of one Haji Ahmed. Qasim asked Rienhardt,  a German commander serving him to kill all the English.  Known as Somru, he came to India to serve in the EIC army. He also served the Rajah of Bhartpur and Mogul ruler Shah Alam; the latter gave him a big estate at Sardhana, UP. He married a beautiful slave girl Begum Sombru - Zeb-un-nissa).

On the night of 5 October 1763 he came to the house of Haji Ahmed and had all of them killed with musket fire, He neither had remorse nor scruples as to kill all without any reason. The dead included 16 civilians and 35 army men including surgeons, Among the civilian included a lady and children . The only survivor was Fullerton. A pillar was erected in 1880 during the time of Gov. Ashly Eden with inscriptions of 28 names. Before that, EIC got the the house where the massacre of the British had taken place.
