Battle of Humaitá

Battle of Humaitá – 18 February 1868
During the War of the Triple Alliance, Marcos Paz, Vice President of the Argentine Republic, died in Buenos Aires from a cholera epidemic brought back from the front, which spread like a curse throughout the summer of 1867–68. The truth is that the Brazilians—by then almost the sole owners of the war, as only the Empire was sending reinforcements and arms—grew serious with Mitre after the disastrous defeat at Tuyú-Cué, and pressured him into returning to Buenos Aires. Constitutionally, his presence was not required, even after Paz’s death, since the Cabinet continued functioning (there was no law governing presidential vacancy), and only eight months remained in the presidential term. But Brazil was eager to hasten the end of the war.
With Mitre removed (never to return), prospects brightened for Brazil. Marshal Caxias resumed command of the allied forces. Perhaps he had never read Frederick the Great, but unlike Mitre, he knew how to win battles.
With the Commander-in-Chief out of the way, things moved swiftly. On 19 January, Admiral Inácio forced the passage at Humaitá; by the 24th, two Brazilian monitors reached Asunción and bombarded the Paraguayan capital. With the river now under Brazilian control, it became impossible for Marshal Solano López to hold the fortifications at Humaitá and Curupaytí. On 10 March, he began withdrawing the bulk of his army via the Chaco route, leaving behind just 4,000 men at Humaitá to cover the retreat. In dugouts, barges, and rafts, the decimated Paraguayan troops—who had defended the Curupaytí–Humaitá line with heroism beyond imagination—crossed the Paraguay River and headed north through the Chaco. At Monte Lindo, they crossed the river again and finally camped at San Fernando. This operation was a feat of leadership and courage: an entire army, with its supplies, wounded, and sick, evacuating a compromised position in the presence of the enemy. They crossed the river twice without, as Arturo Bray notes, “the Brazilian fleet even realising the bold double manoeuvre”.
Colonel Martínez remained in Humaitá as a decoy, to tie down the allied army. But by then the once-impenetrable fortress had lost its strategic purpose. In July, Martínez received orders to abandon it with his remaining men, spiking the 180 cannons that could not be transported. Yet the impatient Marshal Osório was determined to seize the fortress by force and launched an attack with 8,000 men. Martínez responded in Humaitá much as Díaz had in Curupaytí: he let the attackers approach and then unleashed a deadly storm of artillery fire. Osório paid dearly for his ambition to storm the fortress and was ultimately forced to withdraw. Thus ended the last great Paraguayan victory of the war. But unlike Mitre, Osório had the foresight to order a timely retreat and managed to save most of his men.
The cambá (Black Brazilian troops) would enter Humaitá and Curupaytí only after the last Paraguayan soldier had evacuated them on 24 July. On the night of the 23rd, Martínez had sent out the final detachments—men and women—by river. At dawn on the 24th, the Brazilians raised the imperial flag over the now-legendary fortress; shortly beforehand, they had done the same at Curupaytí.
Martínez’s retreat through the Chaco was far from successful. The heroic defenders of the fortress had sacrificed themselves to protect the withdrawal of the main army. As they made their way through the Chaco, they were harassed by vastly superior enemy forces and bombarded from the river by the fleet. Inácio and Osório were determined to exact revenge on Martínez for the three years during which Humaitá had resisted them. Eventually, the depleted Paraguayan garrison was encircled at Isla Poi. They held out for ten days, but hunger and overwhelming numbers forced their surrender. These were the last Paraguayan troops remaining in that theatre of war. Moved by the scene, General Gelly y Obes had the Argentine forces march past “the great heroes of the American epic.” A noble gesture that should fill us with pride.
For a Paraguayan, surrender was unthinkable—even if starvation made it impossible to move, and the lack of ammunition rendered any response to enemy fire futile. Solano López, by now the frenzied “soldier of glory and misfortune”, as Bray puts it, was merciless with those who did not share his unwavering resolve. Victory was no longer possible, and attempts to secure an honourable peace had come to nothing. Thus, for Paraguayans, the only path remaining was death—a chance to give the world a lesson in Guaraní courage.
Colonel Martínez had conducted himself as a hero in the defence of Humaitá and in his doomed retreat through the Chaco. But he had surrendered. It did not matter that he had only 1,200 men and women, lacking uniforms, most with only tattered trousers and military caps, no gunpowder for their flintlocks, and no food—facing a force twenty times their size. The Marshal had surrendered, and that was forbidden for a Paraguayan. The word “surrender” had been erased from the national vocabulary. López declared the defender of Humaitá a traitor.
Three years of unjust and unequal war had transformed the refined Francisco Solano López into a wild beast. He was resolved to die with his country and could neither understand nor forgive any other course of action—not even from his closest friends, his most capable commanders, or his own family. Paraguay came before all else, and for it, he would sacrifice his dearest affections. His actions were certainly not “humane”, but in that final agony, López was no longer a man bound by conventional morality. He had become the very symbol of a Paraguay determined to die standing—like a jaguar of the forest, relentlessly pursued by its hunters.
It was in this final stage of the war that the legend of the monster, the bloodthirsty tyrant, and the great executioner took shape—a narrative that would fuel half a century of Paraguayan liberal historiography. He was accused of terrible acts—and not all were inventions of the enemy. Some accounts are deeply disturbing, but we must place ourselves in the land and time to judge them—amid the tragedy-shrouded Paraguay of the war’s final days. Think of the thousands of Paraguayans who died in battle defending their land, or who perished of hunger or disease behind the lines. Only then can one begin to judge a leader who could not forgive those who showed weakness, who spoke of surrender, or who harboured thoughts other than dying in battle. To understand him, one would need the heart of a Paraguayan and a soul torn by the looming collapse of their homeland.
Terrible things would follow: the execution of Bishop Palacios; the flogging and execution of Colonel Martínez’s wife; the death of López’s own brothers, accused of conspiracy; the imprisonment and whipping of his siblings—even his mother. In this tragic atmosphere, the figure of the implacable Marshal looms large, convinced that for the Paraguayans, under his command, there remained only one path: to contest every inch of their beloved soil—or die.
