General Lopez was attacked on the 13th by a large body of Spanish troops at Las Pozas; the action was severe, and the Spaniards were repulsed. The loss of Lopez was considerable, and among those who fell was Colonel Pragay, an officer who had served with distinction in Hungary. He lost in all about fifty men, but retained possession of the place. He soon perceived that all his hopes of aid from the inhabitants were groundless, and that it would be impossible to maintain himself against the Spanish troops; and determined to conceal himself in the mountains. On their march thither they met several Spanish detachments with whom they had successive engagements, suffering severely in each, and inflicting losses more or less serious upon their opponents. Among the Spaniards who fell was General Enna, a distinguished officer, who was buried at Havana on the 21st, with military pomp. At Martitorena on the 24th, while the remaining body of the invaders were breakfasting, they were surprised by an overwhelming Spanish force, and completely scattered; and from that time forward they seem to have been zealously hunted by the inhabitants of all classes, and by every means. The official reports of the Spanish officers state that the peasants pursued them with dogs, that the negroes aided in their capture, and that every part of the population evinced the most active and devoted loyalty to the Spanish government. On the 28th, Lopez with only six followers, was endeavoring to conceal himself and escape to the sea coast, and on the 29th, he was captured in the Pinos de Rangel, by a guide named Jose Antonio Castañeda, with fifteen peasants. He was at once handed over to a military force under Colonel Ramon de Sago, who had him conveyed by a night march to Havana, where orders were immediately issued for his execution, which took place at 7 o'clock on the morning of September 1st. He perished by the _garrote vil_, an instrument in common use among the Spaniards. It consists of an iron chair, with a back, upon which, at a point even with the head of the person sitting in it, is the instrument of death. This consists of iron clasps made to fit the sides of the head, and a clasp to pass round the throat. From behind is a long iron bar attached to a screw, which put in motion by the executioner giving it a single turn, draws the throat and side pieces tight and at the same time sends an iron rod into the spinal marrow at the neck from behind, causing instantaneous death. This machine was placed upon a scaffold about ten feet high, in the middle of a large square, surrounded by troops. An eyewitness has given an account of the execution. He states that Lopez behaved like a brave man throughout--and walked, surrounded by a guard, to the steps of the scaffold, as coolly as if he were at the head of his troops. He was dressed in a long white gown, and a white cap; his wrists were tied in front and above his elbows behind, with the cords held by soldiers.
