Meanwhile the storm was gathering. Early in June news arrived of the treachery of Nana Sahib at Cawnpore. General Wheeler wrote to Sir Henry Lawrence imploring help and protection for the women and children in the barracks. But Sir Henry Lawrence was in sore straits and could not spare a European soldier. He had been authorised to withdraw from Oudh in case of emergency, and possibly had he beat a retreat from Lucknow to Cawnpore, he might have prevented the massacres. But the step would have been more hazardous and desperate than the abandonment of Peshawar by his brother John. No one anticipated massacre, and reinforcements of Europeans from Bengal might reach Cawnpore at any moment, and stamp out the mutiny and crush the Nana. Retreat from Oudh would not only have involved the loss of a province, but imparted a fatal strength to mutiny and murder from Bengal to the Punjab. The flag of Mohammedan revolt was still floating over Delhi, and had it floated over Lucknow, the second Mohammedan city in Hindustan, British prestige would have vanished for a while from Northern India. [Sidenote: Mutineers in the districts.] In June mutiny and murder were running riot at different stations in Oudh. At some places the atrocities committed on Europeans were heart-rending. At one station there was an outbreak on a Sunday morning. The sepoys rushed into the church during divine service and killed the British magistrate and several officers. Some thirty Europeans, including ladies and children, fled for their lives, and escaped to a station named Mohamdi, where a detachment of Oudh irregulars were quartered under the command of Captain Orr. The very sight of European fugitives taking refuge at the station, drove the sepoys into rebellion. Captain Orr assembled the Asiatic officers and appealed to their common humanity. The men were moved to compassion. They crossed their arms on the head of one of their comrades, and solemnly swore to conduct all the Europeans in safety to another station. [Sidenote: Massacre of Europeans.] The convoy started at five o'clock in the evening; the men on foot or on horseback, and the women and children in a carriage and baggage waggon. Suddenly they found that they were pursued by sepoys. They did their best to hasten on the carriage and waggon, but were soon overtaken and surrounded. A gun was fired, a British officer was shot down, and then followed a general massacre. Women and children were slaughtered with infernal cruelty. A few fugitives escaped the slaughter, but were doomed to privations and sufferings on which it is painful to dwell. [Sidenote: Hostility at Lucknow.]
