Instead of investing the royalists at once, Bolívar committed the error of encamping for the night with all his troops at the village of El Rastro, about four miles this side of Calabozo. Morillo improved this opportunity to abandon the city under cover of night, and fell back on Caracas, by the mountainous route of El Sombrero, where the patriots could not follow him on account of the inferiority of their infantry. Paez then returned to the Apure, while Bolívar remained with the bulk of the army, to be soon after entirely annihilated at La Puerta by the royalist General. But the Genius of the Andes was untiring in his efforts to see his country, and the rest of the South American Continent, free from European oppression.

On the 16th January, 1819, Bolívar joined Paez again at San Juan de Payara with a newly organized corps d’armée, and their united forces amounted to four thousand men. Bolívar, as a recompense for the important services rendered by Paez to his country, raised him to the rank of General of Division, and left him in command of all the forces, while he proceeded to Angostura, where Congress was to meet in February. About this time the royalist Generals, Morillo and La Torre, also joined their forces at San Fernando, amounting in all to six thousand five hundred men of all arms. With these they immediately proceeded to attack the patriots at San Juan in the beginning of February. Paez retreated toward the Orinoco, transported all his infantry to the island of Urbana, and took up a position, with his guard and two squadrons of carabineers, at Cunaviche; the remainder of his horsemen he stationed on the plains of Rio Claro, and a most cumbersome emigration of ten thousand patriot refugees, that followed his camp, was taken to Araguaquen. The plan adopted by Paez on this occasion was precisely the same as the one always practised by him in former campaigns; yet the royalist General was so infatuated by his eagerness to destroy the “Gang of Apure,” that he was easily led away into the wilderness before he was conscious of his danger. On the 11th of February Morillo forced the pass of the river Arauca, and the patriots fell back, keeping their adversary under observation; at night, however, they retraced their steps, and in the morning appeared situated at a short distance in the opposite direction. Morillo counter-marched, and for many days wandered over that wilderness, renewing his efforts to overtake an enemy which kept constantly before him, like the mirage of the desert, and which did him great injury by driving away the cattle. The only means he could employ to overtake his opponent and force him to battle, was to use his cavalry; but this jeopardized the only force which procured the subsistence of the army, and might thus compromise its safety. Not even at night were the royalists allowed to rest in peace. On one occasion Paez caused a number of wild horses to be brought before the enemy’s camp, and tying dry hides to the animals’ tails, they were stampeded with shouts and shots towards the encampment. Imagining themselves attacked by the whole Llanero cavalry, the royalists sprang to their arms and opened fire on the affrighted horses, which caused that night more alarm and confusion among them than the two thousand oxen which Hannibal hurled against the Roman camp. At length, convinced of the inutility of his efforts, Morillo recrossed the Arauca, and in the early part of March established his headquarters at Achaguas.

On the first day of April, General Morillo again resumed the offensive, marching along the left bank of the Arauca and approaching the position occupied on the right bank by Generals Paez and Bolívar; the latter had recently returned from the Congress at Angostura, where he had been elected President of the Republic, and resumed the command in chief of the army. Morillo made several feigned movements to the right and to the left, as if he wished to cross the river, and at noon of the 2d, took up his position nearly opposite that of Bolívar, out of range of the cannon. For the purpose of drawing him forth, General Paez crossed the river with one hundred and fifty horsemen, composed mostly of officers who volunteered for the hazardous undertaking; with these he formed three small columns and advanced upon the enemy. Morillo immediately put all his forces in motion; his infantry and artillery commenced firing, while the cavalry charged upon the small band of patriots, hoping to overpower by numbers the weak columns of the enemy; he himself directed his course toward the bank of the river. Paez, in the mean time, retreated in order, purposely leaving the pass of the river on his rear. Morillo, observing this, and supposing him inevitably lost, detached from the army all the cavalry in pursuit of Paez, and directed his fire upon the right bank, defended by some light troops. As soon, however, as the republican General perceived that the enemy’s horse were at a considerable distance from the army, and in disorder, he faced about suddenly, attacked his pursuers in front and on the flanks, in small groups of twenty men, and without giving them time to recover from their astonishment or to re-form the lines, he routed them, occasioning great loss. In vain they made the most obstinate resistance—in vain the carabineers dismounted—all their efforts were useless; disconcerted and taken by surprise, all those who opposed the vigorous attack were killed upon the spot. The victors pursued the remnants of the force as far as the enemy’s lines, slaying all whom they overtook. Their infantry, thrown into confusion, sought refuge in the woods, the artillery ceased firing, and night prevented the further destruction of the royalist army. On the day following this encounter, Bolívar issued a decree, conferring the cross of Liberators (Libertadores) on all the officers, sergeants, corporals, and soldiers, who fought in this engagement, known in history by the name of Queseras del Medio; while the following proclamation announced to the army the success recently obtained by the republican arms:

SIMON BOLÍVAR PRESIDENT, Etc., Etc.

To the Heroes of the Army of Apure:

“Soldiers! You have just performed the most extraordinary action that can be recorded in the military history of nations—one hundred and fifty men, or, rather, one hundred and fifty heroes, led on by the undaunted General Paez, have deliberately attacked in front the whole Spanish army, under Morillo; artillery, infantry, cavalry, nothing availed to defend the enemy from the hundred and fifty companions of the intrepid Paez. The columns of their cavalry have disappeared under the strokes of our lances; their infantry sought a shelter in the woods; the roar of their cannon was silenced before the breasts of our horses, and only the darkness of night preserved the army of the tyrant from complete and absolute destruction.

“Soldiers! The deed you have performed is but the prelude of what you can accomplish. Prepare then for the combat, and reckon on victory, which you carry on the point of your lances and bayonets.

“Bolívar.

“Head-quarters at Potreritos Marrereños, April 3, 1819.”

After this engagement, Morillo, finding himself again deprived of his cavalry in the heart of the savannas, retreated precipitately to Achaguas, and finally to San Fernando, which place he fortified strongly, and recrossing the Apure, sought a more advantageous position against the attacks of his hovering enemy.
