The explosion was terrific; its effect appalling. The glare lit the whole city for a brief second with a light like a stormy sunset, then upon us showered great pieces of iron and stone with mangled human limbs, the _débris_ of a gateway that for centuries had been considered absolutely impregnable. The first blow against tyranny and oppression had been struck, terrible and decisive. It was the people's call to arms. Would they respond? CHAPTER XXVII. BY THE NAYA'S ORDERS. A SHORT time only did we remain in doubt as to the intention of the populace. The suppressed excitement found vent even before the clouds of choking smoke had rolled away. The signal had been given, and instantly they responded with fierce yells, throwing themselves suddenly upon the soldiers, using weapons that seemed to have been produced like magic. Those who had effected our capture, dumbfounded, first by the appalling explosion, and then by the hostile attitude of the people, released us instantly, being compelled to fight for their lives back towards the smoking ruins of the palace-gate. Within a few moments the great broad thoroughfare, with its handsome houses, became the scene of a most fierce and sanguinary conflict. Rifles flashed everywhere, in the street, from the windows and roofs of surrounding buildings, pouring a fire upon the soldiers so deadly that few succeeded in escaping back to the place whence they came. With startling suddenness I found myself in the midst of this stirring scene, fighting for life beside Omar. Both of us had snatched rifles and ammunition from fallen soldiers, while someone in the crowd had given me a fine sword with bejewelled hilt, which I hastily buckled on in case of emergency. Behind us a great barricade was being built of the first things that came to hand. The houses were being divested of their furniture by a hundred busy hands, and this, piled high, with spaces here and there for the guns, soon presented a barrier formidable, almost insurmountable. The erection of barricades was, we afterwards found, part of the scheme, for in all the principal thoroughfares similar piles were constructed, each being manned by a sturdy body of men, well-armed and determined to hold in check and repulse the attack which they knew would, ere long, be made upon them by the military. The forces of Mo, feared on every hand for their daring and brilliant feats were, we knew, not to be trifled with, and as word had been secretly conveyed to Omar that the Naya, on hearing of the intention of the people, had ordered her soldiers to institute an indiscriminate massacre, we should have to fight hard to save our lives.
