Meanwhile, at the Cantonments, the officers' families and other fugitives had gathered in the Flagstaff Tower, a small circular building on the ridge, where, huddled stiflingly together, they suffered torments almost equal to those of the Black Hole of Calcutta. Their only sure guard consisted of the drummer boys, who, in Sepoy regiments, are usually half-caste Christians. These, armed for the nonce, were posted close round the tower; before it stood two guns served by native artillerymen to command the road from the city; and part of two regiments were still kept to a show of duty, but hourly their demeanour grew more threatening, till, when called upon to move forward, they at length flatly refused. Two or three gentlemen, stationed on the roof of the tower, in the scorching sun, held themselves ready to fire upon the first of their more than doubtful auxiliaries who should break into open mutiny. The Sepoys, for their part, under the eyes of the Sahibs, remained for a time in hesitation, uncertain how to act; and some of them allowed themselves to be deprived of their bayonets, which were stored away in the tower. One messenger had ridden out towards Meerut to demand succour, but only to be shot down by the Sepoys. Another, disguised as a native, made the same attempt to no purpose. Brigadier Graves, still hoping for the arrival of European troops from Meerut, would not for a time hear of retreat. But when it became evident that the handful of band-boys and civilians were all he could trust to defend the tower packed with scared women and crying children; when fugitives from the city brought news that all there was lost; when the Sepoys here began to fire at their officers, whose orders were hardly listened to; when it became plain that the guns would not be used against the mutineers, he saw nothing for it but flight before darkness came on. Towards sunset, the refugees of the tower went off in disorder, on foot, on horseback, in their carriages, each as he could, many of the men hampered with helpless families. The Sepoys did not stop them; some even urged their officers to save themselves; but the guard of a large powder magazine refused to allow it to be blown up; and it proved impossible to carry off the guns.
