As the British fleet was then menacing the port, the three vessels, Neptune, Europa and Asia, were concentrated in the canal of the entrance. With the huge iron beams that closed it and the artillery of the harbor, they acted like forts securing its safety. It seemed as if these land batteries could prevent the landing of any enemy vessel. But the war council wanted to improve upon this measure and decided to sink Neptune and Europa, during the hurried execution of which order two sailors were drowned. Still bent upon what seemed an improvement, two days later the Asia, too, was sunk. The British, supposing the port to be closed, anchored along the coast, landed five thousand men and after defeating the land forces, the fleet entered the canal without encountering serious obstacles. But the Spanish authorities continued to commit more blunders. Appointing as commanders of the land-forces officers of the fleet, the army of course resented this as an insult. The task of mobilizing the troops was entrusted to D. Juan Ignacio de Madriaga; the defense of el Morro had been given to D. Luis Vicente de Velasco, whose second was D. Bartolome Montes, and that of la Punta to D. Manuel Briseno, who was soon relieved by D. Fernando de Lortia. Almost all the army posts were occupied by officers of the fleet. The reasons for these measures which seemed absolutely senseless in view of the critical situation, were hotly discussed and some malicious tongues asserted that the object of this curious disposition was to prevent the fleet from making its escape.
On the tenth of June a British division moved from the leeward part of the fort of Chorrera, a short distance from the port, with the object of landing troops. They met with greater resistance than they had reason to expect; for the defense was here aided by the loyal executor D. Luis de Aguiar, who had been appointed Colonel of the militia. All day his men fought bravely; they consisted of whites and negroes. They expected a supply of powder and ammunition from an official of Guadeloupe, but he by mistake had delivered them at la Caleta. Finally their stock gave out, and, obeying the order of a superior officer, Aguiar withdrew his troops with little loss. The British then advanced about three thousand men strong, until they reached the hill of San Lazaro, where they dug trenches and prepared a new encampment. They also occupied and fortified the height of the caves, called Taganana, where they mounted three cannon and two large mortars. With two vessels, armed with bombs, in the small bay, the fire they kept up helped the camp on the weather-side, at which the chief force was concentrated. They then proceeded to erect batteries on the height of la Cabanas and were at first much molested during their work by Aguiar, Chacon and the guerilla Pepe Antonio, who had collected a force at that point. A detachment of militia under the command of Captain D. Pedro de Morales was sent to reenforce them, but on the next day he was surprised by the British, who thus came into possession of this important place.
In the meantime, the British expedition was beginning to suffer much from incessant rains, alternating with excessive heat. Their work was retarded as much by the weather as by the physical condition of their forces, which began to suffer from the climate and fatigue. The resistance of the Cubans was increasing in proportion as the enemy drew near. During the last days of June, Colonel D. Alejandro de Arroyo landed a body of six hundred men at Pastora battery. Simultaneously the naval lieutenant D. Francisco de Corral placed three hundred men at Norno de Barba. The plan was to spike up the enemy's artillery. But laudable as was the ambition of the commanders, their ability of achievement was not in proportion. Their forces, too, were sadly inferior in number to those of the British. The Captain of the infantry of the fleet, D. Manuel de Frias, was made prisoner, three hundred of his troops were killed and forty men wounded. The force of Col. Arroyo also sustained heavy losses, especially the grenadiers of Arrajon.
A council held at el Morro resulted in the election by the commanders of D. Luis Vicente de Velasco as their head and chief. No man was more able or worthy to fill this responsible position. Untiring in his efforts to defend the fortress, Velasco resolutely and capably endeavored to foil the enemy's designs. But he was out-numbered and the danger grew daily nearer. Though at a great loss to their forces, the British forged ahead and surrounded Velasco with a continuous fire. With the port closed to the Cuban squadron they were free to place their cannon as they went along. The rain of bullets, bombs and grenades was incessant and the breakdown of the bastions inevitable. The garrison seemed to be doomed. The commander declared that it would not be possible to maintain his position without some aid from the camp, but while the walls were being gradually destroyed by the enemy, he did not venture a well organized sortie. On the first of July el Morro was attacked by the batteries which the British had planted on el Cabanas and the fire from three vessels, among them the Cambridge and the Dragon. The valor of Velasco inspired his troops, pathetically small in comparison with those of the British. After seven hours of the hottest fire, the Cambridge and the Dragon were so badly battered that they were forced to the rear. The British lost three hundred men, among them Captain Goostree of the Cambridge. So fierce had been the resistance offered by Velasco and the few cannon at his disposal, that the British camp, which had been pouring a rain of bombs on el Morro, finally ceased firing. So the honor of this day belonged to the Spanish commander.
It is interesting at this point to revert to the journal of the British officer, who took part in this memorable siege of Havana. After reporting under date of July third that their great battery had caught fire, he continues on the following day:
"The Morro was now found to be tougher work and the Spaniards more resolute than was at first imagined. Our people grew fatigued by the heat and hard labour and the want of water near them was a sensible distress, and the disappointment of the Morro's not being reduced so speedily as at first they were made to hope, helped to depress the spirits of the weak and low minds; but we found every want relieved and amply made up for by the Admiral's attention, not only to supply every article that could be asked, but by his own sagacity, foreseeing and his precaution providing everything we could want."
During the following days the British seem to have suffered much from the climate. The writer of the journal records that the men in general "fall down with fevers and fluxes, but few are carried off by them." Admiral Keppel was much weakened by illness and fatigue, but this discouraging entry is followed immediately by a cheerier note, dated July 8th and 9th:
"Every one was exerting himself in his different station and with such zeal as gave fresh hopes to our undertaking, notwithstanding the melancholy scene of the infinite number of sick and the apprehension of the approaching hurricane season."
The British had begun to realize the failure of the naval attempt to reduce el Morro. They tried to fortify themselves in the harbor and established the lee-shore camp on the slope of Aroztegui, the same on which El Principe was situated. From this point they undertook many movements, but were always driven back. In spite of these temporary and local successes the Cuban authorities now fully realized that their situation was almost hopeless and devised various measures to stay the progress of the enemy. The magistrates D. Luis de Aguiar and D. Laureane Chacon were made colonels of the militia. They decided to stop the forays and attacks from that encampment, and D. Aguiar established himself in the Horon and tried to dislodge the enemy from various points to which they had penetrated. His undertaking was successful, as was proved by the number of prisoners taken. The hostile forces at Taganana, however, did much mischief and he resolved to attack them on the night of the eighteenth of July. His troops consisted of peasants and negro slaves and fought so effectively, that he was able to send to the fortress eighteen prisoners, including an officer and many trophies. The governor was so elated by this success that he gave one hundred and four negro slaves, that had taken part, their liberty.
The British officer in his journal alludes in the entries of these days to the heavy losses sustained by the British, but dwells more upon the ravages caused by disease. The sick list increasing, the guards had to be reduced. The necessity of having a supply of fresh meat for the invalids and convalescents worried them much. They had counted upon getting it from Santiago and Bejucal, where the rich plantations and pastures were, and a monastery that promised rich loot. But D. Laureane Chacon anticipated their movements in that direction. He concentrated some troops four leagues leeward from Wajay, and thus not only checked their progress, but by his persistent opposition weakened their forces.
