On the 4th July Mr. Colvin, the Lieutenant-Governor, whose health had been very indifferent for some time, was induced, much against his will, to retire to the fort, and for the time being the management of affairs passed into the hands of Brigadier Polwhele. There was little improvement—indecision reigned supreme. Notwithstanding that the gradual approach of the mutineers from Gwalior and Nasirabad was well known, no preparations were made, no plan of action decided upon. Polwhele, who was a brave old soldier, and had seen a great deal of service, had, indeed, wisely come to the conclusion that the rebels would never venture to attack a fort like Agra, and that, if left alone, they would in all probability continue their march towards Delhi. The available troops numbered less than 1,000 effective men, and Polwhele felt that, by going out to attack the enemy, there would be a grave risk of the seat of government falling into the hands of the disaffected police and city people.
Unfortunately, however, the Brigadier allowed himself to be overruled, and when the mutineers were reported to have arrived at Shahganj, four miles from Agra, he gave way to the cry to ‘Go out and do something!’ and issued orders for the troops to fall in.
A series of mishaps then occurred. It was one o’clock in the afternoon of the 5th July before the column[7] was ready to start; the men in their thick red uniform suffered greatly from the heat and thirst; the enemy, 9,000 strong, with twelve guns, instead of being at Shahganj, were found to be strongly entrenched at Sarsia, some distance farther off. A protracted engagement then took place, and our troops, having expended all their ammunition, were obliged to retreat, leaving many dead and a gun on the field.
