§11. The tragedy was appalling, but the causes were intelligible. About the beginning of the eighteenth century, a Nawab of Bengal, Behar, and Orissa, territories considerably larger than the United Kingdom, had removed his capital from Dacca to Murshedabad, about a hundred miles due north of Calcutta. Here he founded a dynasty, which reigned in peace for some forty years. About 1742 a usurper seized the throne of Murshedabad, and reigned as Nawab. He died of extreme old age in April, 1756, and was succeeded by a grandson, a young man timid and suspicious, surrounded by foes eager to take his life and throne. The new Nawab heard that Governor Drake was sheltering one of his enemies at Calcutta, and strengthening the fortifications; and he ordered the British to surrender the refugee and stop further defences. Governor Drake replied that he knew nothing of any enemies of the Nawab; that he was ready to obey the Nawab in all things; and that he was repairing the defences on the river to prevent being surprised by the French, as Madras had been surprised ten years before. The Nawab was in a fury at this message, and set off for Calcutta in the heats of June with an army of fifty thousand men. [Sidenote: Defences at Calcutta.] For half a century the British had paid little or no attention to their defences. Fort William had been deemed a sufficient protection on the side of the river, and on the land side the native inhabitants had begun to dig a ditch as a defence against the Mahratta horsemen; but the Mahrattas were paid chout to go away, and the ditch was never finished. The Europeans dwelt in houses and gardens along the bank of the river Hughly, on either side of Fort William; and an English Church, the Mayor's Court and some other buildings, covered Fort William on the land side. The native quarter, including a large bazaar, adjoined the Mahratta ditch, and avenues of trees led from the native quarter to Fort William and the European buildings. [Sidenote: Neglected precautions.] Had Governor Drake or any member of his Council possessed a spark of military genius, they might have held Fort William against the Nawab in spite of his superior numbers. There was a garrison of two hundred European soldiers in the Fort. The European residents should have abandoned their houses on the river, and repaired to the Fort with their wives and children. The neighbouring buildings should have been demolished to prevent the Nawab's troops from approaching under cover. The enemy should have been harassed with shells all day and sallies all night, until the Nawab raised the siege. Moreover, the beginning of the south-west monsoon was daily expected. With it would come the ships of the season from Europe. Could the besieged have held out for ten days, they might have been rescued by the ships, just as Charnock and the factors were carried away from Hughly some seventy years before. [Sidenote: Weak preparations.]
