The officers were already in possession of the details of the plan, whose boldness was its main recommendation. The rebels had succeeded in launching their enterprise; the Government would reply by a _coup d'état_. In any case the stroke was aimed at the heart of the revolt, and if it went home the results would be decisive. "The octopus of Rebellion, Gentlemen," said the President to those around him, and pointing to the Revolutionary proclamation, "has long arms. It will be necessary to cut off his head." And though all felt the venture to be desperate, they were brave men and knew their minds. The distance from the palace to the Mayoralty was nearly a mile and a half along a broad but winding avenue; by this avenue, and by the narrower streets on either side, the force advanced silently in three divisions. The President marched on foot with the centre column; Sorrento took command of the left, which was the threatened flank. Slowly, and with frequent halts to keep up communication with each other, the troops marched along the silent streets. Not a soul was to be seen: all the shutters of the houses were closed, all the doors fastened; and though the sky grew gradually brighter in the East, the city was still plunged in gloom. The advanced files pressed forward up the avenue, running from tree to tree, and pausing cautiously at each to peer through the darkness. Suddenly as they rounded a bend, a shot rang out in front. "Forward!" cried the President. The bugles sounded the charge and the drums beat. In the dim light the outline of a barricade was visible two hundred yards off, a dark obstruction across the roadway. The soldiers shouted and broke into a run. The defenders of the barricade, surprised, opened an ineffective fire and then, seeing that the attack was in earnest and doubtful of its strength, beat a retreat while time remained. The barricade was captured in a moment, and the assailants pressed on elated by success. Behind the barricade was a cross street, right and left. Firing broke out everywhere, and the loud noise of the rifles echoed from the walls of the houses. The flanking columns had been sharply checked at their barricades, but the capture of the centre position turned both of these, and their defenders, fearing to be cut off, fled in disorder.
